Abstract
The effect of electrical stimulation of the dorsolateral (DL) and ventromedial (VM) zones of the caudal region of the mesencephalic reticular formation on unit activity in the lateral zone of the posterior sigmoid gyrus was investigated in cats. The mainly excitatory character of mesencephalo-cortical effects was confirmed and predominance of unitary responses with a short latent period (3–12 msec) to stimulation of VM and a longer latent period (20–25 msec) to stimulation of DL was discovered. The experiments showed interaction between VM and DL in their effects on cortical neurons, both those sensitive to somesthetic stimuli (mono-, di-, and polyvalent) and those not responding to electrical stimulation of the skin of the limbs.
