Reflection of visceral afferentiation in unit activity in the caudate nucleus.
Responses of spontaneously active neurons to visceral (splanchnic nerve) stimulation were recorded extracellularly in the head of the caudate nucleus of immobilized cats. The presence of multimodal neurons responding to stimulation of visceral, somatic, and auditory sensory systems in this structure also was established. It is concluded from these facts that neurons  of the caudate nucleus may play a role in the mechanisms of interaction of visceral impulses with somatic and auditory impulses.
