1. Modulação autônoma da resposta taquicárdica do exercício pela ocitocina endógena no complexo solitário vagal em ratos sedentários e treinados, normotensos e hipertensos. / Autonomic modulation of exercise tachycardia by endogenous oxytocin into the solitary vagal complex in sedentary and trained, normotensive and hypertensive rats.
Utilizando Análise Espectral (FFT) para quantificar a variabilidade autonômica no animal intacto, analisamos pressão arterial, intervalo de pulso (IP) e fluxo sangüíneo no repouso e no exercício, em ratos normotensos (WKY) e hipertensos (SHR), sedentários (S) ou treinados (T), após pré-tratamento do NTS/DMV com veículo e antagonista de ocitocina (O

2. Organization of synaptic transmission in the mammalian solitary complex, studied in vitro.
1. Synaptic transmission and neuronal morphology were studied in the nucleus tractus solitarius and in the dorsal vagal motor nucleus (solitary complex), in coronal brain-stem slices of rat or cat, superfused in vitro. 2. Electrical stimulation of afferent fibres of the solitary tract evoked two different types of post-synaptic response recorded intracellula

3. Impact of antral mechanoreceptor activation on the vago-vagal reflex in the rat: functional zonation of responses.
1. Activation of gastric sensory afferents alters gastric motor and secretory function via the gastric vago-vagal reflex. In this report, we investigated in the rat the impact of gastric mechanoreceptor activation on the brain stem components of the reflex, which are located in the dorsal vagal complex (DVC), i.e. the nucleus of the solitary tract (NTS) and
