[Convergence and interaction of visceral, somatic and visual excitations in individual neurons of the cat lateral geniculate bodies].

In anesthetized cats, electric stimulation of the vagal, splanchnic, pelvic, and ischiatic nerves and of the mesencephalic RF entailed both prolonged diffuse acceleration or inhibition of firing rate and phasic responses of single LGB neurons. Somatic stimuli were found to be the most effective. Visceral and somatic stimuli either facilitated or inhibited the activity of neurons caused by LGB photo-stimulation. The data obtained indicate that visceral and somatic stimulation tells on the optical information in the LGB neuronal apparatus.
