1. Narayanan, Darshana Z. THE ORGANIZATION OF ACTION IN THE FETUS: Prenatal development of orofacial movements in marmoset monkeys .

Degree: PhD, 2015, Princeton University

In primates, a number of vocal behaviors are present at birth. These behaviors are often dubbed as `innate¿ but how they develop remains mysterious. As opposed to simply appearing de novo at birth, we hypothesize that vocalizations begin to self-organize prenatally through the interactions between spontaneous neural activity, fetal biomechanics and the physical constraints of the uterine environment. We investigated how fetal movements relate to the postnatal mouth movements required for vocal production by performing ultrasound imaging on awake, pregnant marmoset monkeys (Callithrix jacchus). Our expectations were two-fold (1) body parts linked to different behaviors become increasingly differentiated; and (2) body parts used for the same behavior become increasingly coordinated. We found that orofacial and head movements occur together early in gestation but gradually decouple and move independently by the end of gestation. Critically, we also observed that signature features of marmoset infant calls emerge prenatally as distinct patterns of orofacial movements: Late in gestation, the duration and syllable number of the phee call and twitter call ¿ calls produced by marmoset monkeys on the first postnatal day ¿ are evident in the orofacial movements of fetal marmosets. Our study shows that aspects of vocal behaviors in marmosets have a period of prenatal development. Advisors/Committee Members: Ghazanfar, Asif (advisor).

2. Romaiana Picada Pereira. INGESTÃO DA TINTURA DE VALERIANA OFFICINALIS PROTEGE DA DISCINESIA OROFACIAL INDUZIDA POR RESERPINA EM RATOS.

Degree: 2009, Universidade Federal de Santa Maria

Considerando as hipóteses do papel da neurotransmissão gabaérgica e do estresse oxidativo no desenvolvimento de movimentos orais associados a neuropatologias importantes, o presente estudo investigou a possível habilidade da tintura de V. officinalis na prevenção dos movimentos de mascar no vazio (MMV) induzidos por reserpina em ratos. Os animais foram tratados com reserpina (1 mg/Kg, s.c.) e/ou com V. officinalis (na água de beber). MMV, atividade locomotora e medidas de estresse oxidativo foram avaliadas. O efeito neuroprotetor da V. officinalis contra a toxicidade celular induzida por ferro foi investigada em fatias de córtex cerebral. Além disso, fez-se a identificação do ácido valérico e do ácido gálico por HPLC na tintura de V. officinalis. Os resultados demonstram que a reserpina causou um aumento nos MMV quando comparado com o seu veículo e o co-tratamento com V. officinalis foi capaz de reduzir a intensidade dos MMV. A reserpina não alterou de forma significativa alguns parâmetros de estresse oxidativo analisados nas estruturas do cérebro (córtex, hipocampo, estriado e substantia nigra). Porém, uma correlação positiva entre os níveis de oxidação da DCF (uma estimativa do estresse oxidativo) no cortex e o número de MMV (p<0.05) foi observada. Além disso, foi observada uma tendência a haver uma correlação negativa entre a atividade da Na+/K+- ATPase na substantia nigra e o número de MMV (p= 0.055). In vitro, V. officinalis protegeu as fatias de córtex cerebral contra a neurotoxicidade induzida por ferro. Desta forma, pode-se concluir que a V. officinalis apresentou efeitos neuroprotetores em ratos tanto in vitro quanto in vivo, ou seja, reduziu a neurotoxicidade induzida por ferro e os MMV induzidos por reserpina, provavelmente via modulação do estresse oxidativo em núcleos específicos do cérebro e sua ação gabamimética. Porém, os mecanismos envolvidos nesta atividade protetora necessitam de mais investigações para melhor entender a ação da V. officinalis.

Considering the hypothesis that GABA and oxidative stress are involved in the development of oral movements associated with important neuropathologies, the present study investigated the possible ability of V. officinalis in the prevention of vacuous chewing movements (VCMs) induced by reserpine in rats. Adult male rats were treated with reserpine (1 mg/kg, s.c.) and/or with V. officinalis (in the drinking water). VCMs, locomotor activity and oxidative stress measurements were evaluated. The neuroprotective effect of V. officinalis against iron-induced cell toxicity was investigated in brain cortical slices. Furthermore, we carried out the identification of valeric acid and gallic acid by HPLC in the V. officinalis tincture. Our findings demonstrate that reserpine caused a marked increase on VCMs and the co-treatment with V. officinalis was able to reduce the intensity of VCM. Reserpine did not induce oxidative stress in cerebral structures (cortex, hippocampus, striatum and substantia nigra). However, a significant positive correlation between…
