An examination into the influence of observed gaze cues on motor output.

Richardson and colleagues (2013) demonstrated oculo-manual spatial interference by finding that the finger trajectory in a vertical tapping task deviated toward the direction of a concurrent saccade. It was proposed that the entrainment of the hand to the eyes was in part a function of generalized motor planning. Human action observation research has shown that cortical motor planning is also active during action observation (e.g. Buccino et al. 2001; Decety et al. 1997), which can lead to other forms of spatial interference (Kilner et al 2003). We hypothesized that because motor planning subserves both observation and execution of action, simply observing the horizontal saccades of another person would cause sufficient recruitment of oculomotor planning structures, that would result in finger tap trajectory deviations toward the direction of the observed saccade (but would not do so in a non-biological observation control condition).19 participants performed 24 trials of vertical finger taps under three different visual conditions. They were required to: a) saccade horizontally between targets; b) fixate on a biological stimulus (i.e. a video of horizontally saccading human eyes); or c) fixate on a non-biological control stimulus (horizontally moving black dots) while tapping their finger to an auditory metronome beat presented at a 750ms intervals. Results from the saccading condition replicate Richardson et al’s (2013) entrainment effect. That is, finger taps deviated to the left when participants saccaded left, and to the right when executed with a rightward saccade. Contrary to expectations however, there was no entrainment induced by observing either the biological stimulus or the control stimulus. This suggests that competing motor plans (eyes and hands) are necessary to induce interference. Further, simply observing eye movements do not recruit the same oculomotor planning networks as action execution.

▼ Neurophysiological and behavioural research has suggested that multiple potential actions are represented simultaneously. For example, neural activity associated with multiple potential actions has been observed in premotor structures of monkeys. Also, when humans are presented with two potential reach targets, they initially aim their reach toward the midpoint, or spatial average, of the targets. Within the context of the neurophysiological findings, it has been suggested that this ‘spatial averaging’ phenomena reflects competing neural activity associated with multiple motor plans being implemented simultaneously. However, it is also possible that the initial trajectory represents a perceptual average of spatial locations. The goal of this thesis was to examine these two accounts of spatial averaging. An initial experiment tested the idea that multiple motor plans specifying multiple motor parameters are prepared simultaneously. Participant's reached toward multiple potential targets, one of which was cued after movement onset as the movement target, that varied in location and orientation. Hand direction and orientation were found to be biased by both the spatial distribution and orientation; suggesting that fully specified motor plans are prepared simultaneously to potential targets. The second experiment tested whether spatial averaging behaviour reflects the use of a perceptual representation or a motor representation of potential targets. Participants preformed a rapid reaching task in which an obstacle blocked the movement to one of two potential targets. The initial movement direction was found to be a weighted average of the movement directions to each target; as opposed to being an average of the target locations. In chapter four, a visuomotor adaptation task in which individuals learned to produce identical movements to two separate visual targets allowed the perceptual representation and the motor representation of the targets to be dissociated and the predictions of each account to be tested separately. The initial movement direction was shifted in the direction of the adaptation; providing support for the idea that multiple motor plans are computed simultaneously. Taken together, the results presented herein provide support for the idea that the brain prepares multiple movement plans in advance of deciding between potential actions.

▼ The control of object manipulation tasks involves the close interplay of predictive and reactive control mechanisms. For example, when lifting an object, people typically predict the weight based on object size and material as well as sensorimotor memory obtained from previous lifts of the object. When lifting objects with a precision grip, people increase vertical load force to a target level that slightly exceeds the predicted weight. When the object is heavier than expected, the mismatch between expected and actual tactile signals associated with lift-off triggers a corrective action within ~100 ms, that involves probing increases in load force that continue until the object is lifted. Here we investigated whether this correction action can be adaptively influenced by experience. Participants repeatedly lifted an object that was instrumented with force sensors to measure the forces applied by the fingertips, with weight that could be varied without the knowledge of the participant. In 80% of trials, the weight was set to 2 N and, in different blocks of 110 trials, the remaining 20 % of trials (2 trials randomly selected from each successive 10 trials) was set to either 4 or 6 N. We found that the rate of change of the reflexively triggered increase in load force that occurred in the 4 or 6 N trials, scaled with the additional weight. That is, following the initial increase in load force to ~2 N, the subsequent increase in load force was more rapid for the 6 N object than the 4 N object. In contrast, the onset time of the reactive increase in load force was independent of the additional weight. Finally, this adaptation of reactive load force control took place quickly and was evident after only a few lifts of the heavier weight. These results indicate that the reactive increases in load force that occur when a lifted object is heavier than expected can be adapted and tuned, to refine behavior. This further suggests that multiple predictions can be generated about object weight when lifting.

In this thesis, we study the neurophysiological basis of handedness or the individual preference for use of a hand, known as the dominant hand. Any motor task involves the decision of which arm to perform it with or how the two arms must coordinate. If using only one arm, humans show a preference to use their "dominant" arm, which is often more dexterous and skillful than the other one. Hand dominance also impacts bimanual coordination, as a different role is associated to each arm during a bimanual task. Such differences across the two arms cannot be explained based on anatomical aspects, since the two arms are equally strong and have the same freedom of movement. It has been reported that each arm has a specialized behavior, with the dominant arm having a better trajectory control and the non-dominant arm being more stable in front of perturbations. And yet it is still unclear why we have a dominant arm and what the neurophysiological basis of handedness is. Amounting evidence has highlighted the importance of feedback when performing skilled movements, however, there is no control framework able to account for the differences in performance across limbs. Given the importance of feedback in motor control, we suspected that handedness was likely related to distinct feedback control strategies. In this thesis, we use optimal and robust control theory to model different feedback control strategies, and show that such distinct strategies can capture the differences in behavior observed across the two arms. We also study how the central nervous system coordinates the two arms during a bimanual task. Using optimal control theory, we highlight the impact of the joint configuration of the upper-limbs on how the two arms share the effort during a bimanual task. We show that the arm with the best spatial relationship between effort and target goal is the arm that produces the most significant effort during a bimanual task. Altogether, the results of this thesis offer a new perspective on the differences in behavior across the two arms and highlight the fact that handedness arises from distinct feedback control strategies.

▼ A recent theory of motor control, based on optimal feedback control, posits that voluntary motor behaviour involves the sophisticated manipulation of sensory feedback. Although this theory can explain how people move in the world, it does not specifically describe how this control process is implemented by the nervous system. In this thesis, we propose and explore one physiological implication of this theory. Specifically, we hypothesize that rapid feedback responses should possess the key functional attributes of voluntary control because these two systems share a common neural pathway through motor areas of cerebral cortex. Our first four studies were designed to elaborate the functional attributes of the long-latency stretch reflex, a fast feedback response which occurs 50-100ms following the mechanical stretch of a muscle. Consistent with our hypothesis, we found that the long-latency response possesses many attributes commonly reserved for voluntary control: the long-latency response is continuously modulated by subject intent (Chapter 2), it compensates for the size-recruitment principle of the motoneuron pool (Chapter 3) and it accounts for the mechanical properties of the upper-limb (Chapter 5). Further investigation revealed that the long-latency response can be decomposed into two functionally-independent processes (Chapter 4), and that one of these components contributes all of the sophistication observed in Chapters 2 and 3. The goal of our fifth study was to investigate the neural basis of the long-latency response (Chapter 6). Our results provide strong evidence from both single-neuron recordings in non-human primates and transcranial magnetic stimulation in humans that primary motor cortex, which is known to be a critical node for voluntary control, also contributes to the sophistication of the long-latency response. Taken together, the studies presented in this thesis demonstrate that the long- latency response possesses several functional attributes typically reserved for voluntary control and that this sophistication likely arises via a transcortical pathway through primary motor cortex.

▼ When making a movement, the brain receives sensory feedback about the consequences of that action. If sensory feedback differs from predicted, the brain experiences an error, driving adaptation and improving subsequent movements. How much the brain adapts to error is governed by its sensitivity. Computationally, sensitivity is a scaling factor, specifying the relative amount of adaptation that occurs, while theoretically it is a quantification of the error’s value. In children with autism spectrum disorder (ASD), the response to sensory feedback appears abnormal. In particular, they are hyperresponsive to proprioceptive feedback and hyporesponsive to visual feedback. Here, we hypothesized that these sensory abnormalities would be manifested as an increased sensitivity to proprioceptive error and a decreased sensitivity to visual error. Further, we hypothesized that this pattern of error sensitivity would be related to anatomical abnormalities in the cerebellum, known to be a neural substrate of motor learning. Typical models of adaptation assume sensitivity to error to be a constant; however several studies contradict this, reporting a non-linear relationship between adaptation and error. Therefore, we first characterized sensitivity in healthy adults with a reach adaptation task, in which we perturbed their movements both proprioceptively and visually. By normalizing the trial-to-trial change in motor commands by the error size, we isolated sensitivity to error. We found that, for both visual and proprioceptive errors, sensitivity declined with increasing error size. Interestingly, the probability of a complex spike in cerebellar Purkinje cells, previously believed to be a neural representation of an error, declined with increasing error as well. We therefore posited that complex spikes represent sensitivity to error during cerebellar adaptation. We then repeated our paradigm on children with ASD. As hypothesized, we found increased sensitivity to proprioceptive error and decreased sensitivity to visual error, relative to healthy control children. In these same subjects, we used anatomical MRI to measure the volume of the senosorimotor region of the cerebellum. We found this region was significantly smaller in children with ASD, and that sensitivity was a predictor of volume, identifying a potential neural substrate for the sensorimotor abnormalities seen in ASD.

▼ The role of lateralization in the control of human motion is difficult to assess. Lateralization of skilled control, or handedness is a readily observable yet incompletely understood facet of human control of the upper extremity. Despite the ease with which hand preference is identified, the specific mechanisms producing these differences in control are difficult to integrate into existing models of control. The Dynamic Dominance hypothesis of human motor control, builds a general theory of human motor control from descriptions of the lateralization of hand and arm control. The Dynamic Dominance hypothesis stipulates that the advantage displayed by the dominant limb is in the anticipation and utilization of the dynamics of movement across multiple segments. Additionally the Dynamic Dominance hypothesis proposes that the non-dominant arm has an advantage for specifying limb postures, which often results in advantages in final position accuracy. Further these advantages are due to the lateralization of neural circuits specialized to regulate different aspects of movement. Importantly, the Dynamic Dominance hypothesis proposes that movement of each arm relies on both contralateral and ipsilateral cortex to supply different aspects of control. The studies presented in this dissertation explore the generalizability of Dynamic Dominance as a model of control. These studies address three specific limitations of past work. First, since Dynamic Dominance was developed based upon data collected from constrained, planar reaches, we wished to test how well the hypothesis generalized to conditions in which gravity must be accounted for. Second, we tested the feasibility of a simple control model that simulated the discrete contribution of the two proposed hemisphere mechanisms to control to of a single movement. We were particularly interested in the ability of such a model to describe the differences in control observed in dominant and non-dominant arm movements. Finally, we examined predictions of how each hemisphere is activated during unilateral reaching. Based upon the control requirements of the task, we predicted the activity over specific areas of cortex, based upon dynamic Dominance. These studies extend our understanding of lateralization of the human motor control system.

▼ One of the central issues in the field of motor control is how movements are controlled, or more specifically, what is controlled by the central nervous system (CNS). Typically, movements involve the interaction of multiple effectors to produce a desired output. An attractive approach to addressing this problem is studying the interaction of fingers in multi-finger tasks. One issue that arises when studying finger interaction is that single finger force production cannot be performed independently of the other fingers. A behavior known as enslaving occurs when one tries to press with a single finger – the other fingers also produce force. The dissertation was divided into two parts. The purpose of the first part of the dissertation was to use single- and multi-finger pressing paradigms to investigate: 1) anatomical changes induced in fingers due to changes in configuration and force production of a single finger; 2) force changes of fingers due to an involuntary perturbation of a single finger during a four-finger pressing task; and 3) force changes of fingers due to voluntary pressing of a single finger which followed a task that required establishing a total force stabilizing synergy among the four fingers. The main findings from the first part of the dissertation were: 1) the changes in configuration and force production of a single finger resulted in no significant anatomical changes in the other fingers; 2) an involuntary perturbation of a single finger resulted in the non-perturbed fingers displaying changes in force that acted to stabilize task performance; and 3) following the establishment of a force stabilizing synergy the CNS was able to quickly abolish that synergy such that typical finger enslaving was observed during voluntary pressing with a single finger. The second part of the dissertation investigated whether it is plausible the CNS uses hypothetical control variables (called neural commands) instead of the mechanical variables (force in our case) to control and regulate movements. The neural commands are essentially free of the enslaving effects. Estimating neural commands is non-trivial and a methodological study was performed to determine the best procedure for computing neural commands. It was determined that a neural network model provided the most accurate estimation of neural commands. Analytical inverse optimization (ANIO) and uncontrolled manifold analysis (UCM) were used to compare performance of neural commands to finger forces in a multi-finger pressing task. Based on the experimental results it appears plausible that the CNS may operate in the space of neural commands. The neural commands performed equally as well to the forces in terms of optimality and outperformed forces in terms of the structure of variance. These findings agree with the notion that the CNS controls patterns of muscle activity, not individual muscles and the findings also support a synergistic hierarchical organization of the elemental variables.

▼ Background: Vision will guide the actions and behaviors that allow us to circumvent environmental obstacles. When passing through a gap, individuals will consistently elicit a shoulder rotation (SR) if the gap is 1.4 times their shoulder width (SW) or narrower, with this behaviour being produced under various environmental conditions. Although a few studies have investigated perceptual predictions regarding gap passage, the effect of physical activity and the differences between trained and untrained athlete’s behaviours has not been examined. This study investigated the perceptual judgements of non-athletes and varsity athletes regarding the action they would utilize to pass through a dynamically converging gap, and whether varsity athletes experienced any sport-specific benefits from a bout of physical activity. Methods: Part 1) Eleven non-athletes walked (in VR) along a 7.5 m path while two avatars moved towards them on converging angles, creating perceived aperture widths of 0.8, 1, 1.2, 1.4, 1.6, and 1.8 x SW at the theoretical time of crossing. At 2 seconds prior to contact the screen went blank and the subjects identified whether they would rotate their shoulders to pass through the two or not. The non-athletes completed the study on two counterbalanced days, the exercise day involved a 14-minute exercise protocol (a 2-min warm-up, 10-min graded exercise bout, and a 2-min cool down), before repeating the task again. On the rest day participants sat quietly for 15 min before competing the task a second time. Part 2) Eighteen varsity athletes were randomized into an exercise or rest group. Both groups completed a single protocol from Part 1 (either the exercise or rest day). Results: Both the non-athletes and varsity athletes’ perceptions were modulated to body-scaled judgments, such that smaller apertures were perceived to require significantly more rotations then larger ones. After exercise, the non-athletes critical point became more conservative (from 1.13 to 1.25 x SW), while the varsity athletes critical point got closer to their true SW (from 1.21 x SW to 1.17 x SW). Exercise had no effect on non-athlete’s response time (p=.47) or accuracy (p=.22) but shortened the varsity athletes response time (p=.033) and improved their accuracy (p=.046) from 69% to 82% correct perceptual judgements. Conclusion: Overall, the results of the current study demonstrated that both non-athletes and varsity athletes successfully modulated their perceived SRs to gap width. It is possible the arousal following physical activity allowed the athletes enhanced visuomotor skills to be transferable to the current task by making it more sport-specific. The results from this study provide insight as to how individuals perceptually circumvent apertures without producing actions and provides further understanding as to how perceptions and actions work together to guide locomotion.

▼ La stabilità della stazione eretta di un gruppo di ballerine professioniste è stata comparata con quella di un gruppo di soggetti sedentari per verificare l'influenza dell'apprendimento di posture complesse su altre forme di stazione eretta. Sono state considerante un set di 5 posture diverse: in due configurazioni i piedi erano paralleli e distanza intermalleolare di 10 e di 20 cm; in altre due i piedi erano leggermente extra ruotati con angolo di apertura di 20° e distanza intermalleolare di 15 cm e fortemente extra ruotati con angolo di apertura di 140° con i talloni accostati; nell'ultima configurazione i piedi erano allineati lungo il piano sagittale con tallone e punta accostati. Le varie posizioni presentavano diversi livelli d' instabilità ma solo le ultime due erano configurazioni poco comuni per il gruppo di sedentari mentre solo l'ultima era poco familiare per le ballerine. La stabilità posturale è stata valutata anche in condizioni dinamiche: i soggetti erano invitati ad eseguire l'elevazione laterale o la flessione in avanti di un arto rimanendo in equilibrio sull' arto controlaterale. La quantificazione della stabilità posturale veniva effettuata tramite una pedana dinamometrica determinando la posizione del Centro di Pressione (CoP). La ricostruzione della traiettoria del CoP permetteva la determinazione di parametri spaziali (area complessiva del CoP, lunghezza della sua traiettoria), parametri relativi alla variabilità temporale sull'asse antero-posteriore e medio laterale (Root Mean Square Distance e Approximate Entropy) e parametri riguardanti il contenuto in frequenze del segnale oscillatorio (Mean Power Frequency). La quantificazione della stabilità posturale, sia in condizioni statiche che dinamiche, ha evidenziato differenze significative tra il gruppo delle ballerine e quello dei soggetti di controllo solo nel caso in cui i piedi erano completamente extraruotati per la condizione statica e nel caso dell'elevazione dell'arto lateralmente per la condizione dinamica. Le ballerine, quindi, mostravano un miglioramento importante solo in quelle condizioni specificatamente associate alla pratica della danza classica mentre non sono state osservate differenze tra i due gruppi nel caso delle posture piu' comuni o della postura con i piedi allineati. I dati sperimentali riportati in questa tesi permettono di affermare che la pratica della danza classica permette l'apprendimento di posture strettamente specifiche agli esercizi praticati senza alcuna generalizzazione verso altre forme di stazione eretta.

▼ The purpose of this study was to compare reaction time and postural stabilization between activity groups in older adults. These variables are important because older adults are at a high fall risk and two major contributors to fall risk are postural stabilization and reaction time. This study examined if the activity group of an older adult had any influence on reaction time and postural stabilization. Fifty-nine older adults aged 66.46 ± 9.47 years old were used in the study. Thirteen subjects were in the master’s athletes which are individuals over the age of 40 who competed in a nationally sanctioned event within the last 6 months and complete at least 150 minutes of aerobic exercise per week, 27 were in recreationally active, which are individuals who complete at least 150 minutes of aerobic exercise per week but do not compete, and 19 were in sedentary activity group, which are individuals who do not exercise at least 150 minutes per week of aerobic exercise. Choice and simple reaction time were measured to determined how quickly the individual could respond to a stimulus. Postural stabilization was measured using a Biodex Balance System. After comparing the activity groups using one-way ANOVA’s, no statistically significant differences were found between activity groups in simple reaction time, F(2, 56) = 2.77, p = .07, choice reaction time F(2, 56) = 2.29, p = .11, or postural stabilization scores F(2, 48) = .697, p = .51. The cohen’s f test found moderate effect sizes in the simple reaction time, f = 0.31, and choice reaction time, f = 0.29. The cohen’s d test found the effect size was largest, d > 0.50 between sedentary and master’s athletes activity groups and between recreationally active and master’s athletes activity groups for all three variables. The main conclusion is that there were no significant differences between activity groups but that may be from the small number of subjects. The effect sizes showed a trend that master’s athletes had the best scores overall for each variable. Advisors/Committee Members: Michelle Gray, Robert Elbin, Kaitlin Gallagher.

▼ One enduring question in the study of speech concerns the nature of the link between speech perception and production. Although accumulating evidence suggests that these two facets of spoken language are tightly coupled, the cognitive structure and neural organization underlying the interactions between the two processes are not well understood. In this thesis, I focus on questions that arise from observations related to when individuals are both talking and listening, and assess the sensitivity of talkers and listeners to the same change in the acoustics of speech. First, I aim to elucidate the neural substrates of auditory feedback control during vocalization by examining the brain response to acoustic perturbations towards auditory concomitants of speech using functional magnetic resonance imaging (fMRI) (Chapters 2 and 3). I demonstrate, for the first time, an extensive network of brain regions involved in the detection and correction of auditory feedback errors during speech production, for which three functionally differentiated neural systems can be delineated. Then I set out to address the online perception of own voice identity as individuals are talking. Chapters 4 and 5 measure the perceptual sensitivity of individuals to the auditory concomitants of their own speech by presenting temporally gated auditory feedback in stranger’s voices during talking. The results show that people perceive stranger’s voices as a modified version of their own voice and adjust their vocal production accordingly, when their utterances and heard feedback are phonetically congruent. Chapter 6 further examines this perceptual effect by using experimental paradigms in the domain of body ownership and shows that the misattribution of the stranger’s voice, is not predicted by individual differences in suggestibility; rather it is related to the integration of multimodal cues. In summary, by focusing on how the acoustics of speech are simultaneously processed for both the perception and production sides of spoken language, the series of studies add significantly to our understanding of the psychophysical, cognitive and anatomical relationships between speech perception and production, and are relevant to a wide range of clinical pathologies (e.g., stuttering, schizophrenia).

▼ Multiple Sclerosis is a neurological disease which affects an estimated 2.5million people worldwide. People with Multiple Sclerosis often experience high rates of falls, which have been associated with age, disability, and increased postural sway. Additionally, people with Multiple Sclerosis often exhibit muscular weakness and poor responses to perturbations. PURPOSE: To determine if trunk stability and postural control are altered among PwMS and if trunk muscle activity is correlated with postural stability. METHODS: Ten participants with a physician's diagnosis of Multiple Sclerosis (9 female, 1 male) were included in this study. Ten healthy controls were matched for age, height, weight, and gender. To analyze postural sway, participants stood quietly on a force platform for 30s with eyes closed and 30s with eyes open. Participants were then administered anticipated and unanticipated perturbations to the trunk while in a semiseated position. Finally, participants underwent three maximum isometric contractions. Surface electromyography was collected at the erector spinae muscle group 3cm lateral to the L3 spinous process. High speed motion capture was used to determine peak accelerations of a reflective marker placed approximately at the C7 vertebrae. RESULTS: No statistical differences were observed in trunk accelerations following perturbations. However, people with multiple sclerosis exhibit significantly greater trunk muscle activity following anticipated perturbations (p = 0.04, d = 0.98). Additionally, numerous large significant correlations were found between trunk muscle activity and postural sway. People with Multiple Sclerosis who experience falls appear to have greater trunk muscle activity following unanticipated perturbations than non-fallers (p = 0.07, d = 1.47). However, non-fallers may be better able to anticipate perturbations than fallers (p = 0.10, d = 1.29). CONCLUSION: People with Multiple Sclerosis demonstrate greater trunk muscle activity in response to perturbations than healthy controls. Trunk muscle activity is significantly correlated to postural sway in people with multiple sclerosis. People with Multiple Sclerosis who experience falls show greater trunk muscle activity following perturbations than non-fallers. However, non-fallers may be better able to anticipate perturbations than fallers. Advisors/Committee Members: Bradley Bowser.

▼ Fine motor control is important for the completion of many activities of daily living, such as writing, eating, buttoning a shirt, and texting. All these tasks require a high amount of continuous coordination and regulation of increasing and decreasing forces between multiple digits using sub-maximal force levels to successfully accomplish the task. Thus understanding the coordination of force regulation by the thumb and index finger at these sub-maximal force levels is a relevant topic especially for rehabilitation and instrumentation. This study was designed to investigate how accuracy and smoothness of performance of an isometric pinch force tracking task is affected by changing the level of forces required to perform the task and by different combinations of application and release of force by the thumb and index finger. Twenty two healthy, right handed adult participants between the ages of 18-30 were asked to manipulate a cursor to track a moving target ball counterclockwise around a prescribed path using the thumb and index finger of the right hand only. The goal of the task was to keep the cursor as close as possible to the moving target throughout the entire trial. Each participant was given 50 practice trials: 25 at 24% MVC and 25 at 12% MVC. For the 40 experimental trials, participants returned 24 hours later to complete 10 trials at each of the following force levels: 4%, 8%, 16%, and 32%. RMSE and CVE were calculated for each digit (thumb and index finger) as well as the combined digits and were used as indicators of accuracy and smoothness, respectively. Results showed significant differences in all dependent variables with p-values less than 0.05. Task performance accuracy was found to decrease as force level increased, whereas smoothness was found to decrease as force level decreased for all three. These findings suggest that varying force levels and combinations of force application and force release can change performance of this fine motor task and should be further investigated in order to better understand mechanisms involved and for implementing new designs of equipment and diagnostic tools.
