title: [Visceral, vagal, and splanchnic projections in the region of the ventro-medial nucleus of the hypothalamus in cats].
abstract: In anaesthetized cats, evoked or unitary potentials were produced in the hypothalamus by electrical stimulation of splanchnic and vagus nerves. Responses were recorded bilaterally in an area corresponding to the median nucleus. They were greater for the splanchnic stimulation than for the vagal one. The stimulation parameters and the response latencies suggested that the afferent fibres involved belonged chiefly to B and C nerve components. From this preliminary study, it will be possible to analyze the effects of different splanchnic and vagal afferents on the unitary activity of the ventro-median nucleus.
