[Unit responses of the amygdaloid corticomedial nuclei to stimulation of the vagal, splanchnic and sciatic nerves].

Bipolar recording revealed EPs of maximal amplitude in stimulation of vagus, splanchnic and sciatic nerves in the region of amygdaloid corticomedial nuclei in anesthetized cats. A high degree of reactivity (68.3%) of neurons was found in this region to single-shock stimulation of the peripheral nerves. The majority of neurons revealed tonic reactions. A high degree (57.1%) of afferent convergence from different visceral and somatic systems was found, the responses of the convergent type neurons being mostly unidirectional and identical in pattern. Sensory properties of neurons of corticomedial amygdaloid nuclei are discussed.
