Participação do fator de liberação de corticotrofina (CRF) no Locus coeruleus na resposta respiratória à hipercapnia
(Universidade Federal de São Carlos, 2015-09-04)
Locus coeruleus (LC) is a pontine noradrenergic group that acts as a central chemoreceptor to CO2/pH and it is involved in the cognitive aspects of stress response and it is associated with a large number of physiological ...
Participação dos neurônios catecolaminérgicos do tronco encefálico no controle respiratório
(Universidade Federal de São Carlos, 2015-10-02)
It is well know that the respiratory network, undergoes significant development
in the postnatal period. Among various processes, the maturing of the catecholaminergic

Modulação autonômica cardíaca durante o exercício no peixe de respiração aérea bagre africano, Clarias gariepinus
(Universidade Federal de São Carlos, 2015-09-04)
Teleost fishes were the first vertebrates to possess double autonomic innervation of the heart,
where a balance between adrenergic and cholinergic actions determine heart rate (ƒH). Among
teleosts, air breathing (AB) ...
Aversão ao contexto associado ao estresse de derrota social em camundongos : um estudo etológico
(Universidade Federal de São Carlos, 2015-04-01)
Aggressive interactions between conspecific animals have been used as an
ethological source of social stress to study some aspects of social anxiety. Through this
work we used a new experimental protocol in order to ...
Avaliação da participação dos receptores N-metil-D-aspartato (NMDA) e do Fator de Liberação de Corticotropina (CRF) nos efeitos aversivos do óxido nítrico no núcleo intersticial da estria terminal de camundongos
(Universidade Federal de São Carlos, 2015-05-28)
It has been shown that the bed nucleus of the stria terminalis (BNST) of rats contains nitrergic neurons, which are activated during animal exposure to aversive stimuli. BNST is also populated by glutamatergic and ...
