Abstract

Responses to electrical stimulation of fibers of the medial lemniscus arising in the thalamocortical fibers running to the primary somatosensory cortex were investigated in acute experiments on cats anesthetized with pentobarbital. Application of penicillin to the somatosensory cortex and the consequent development of paroxysmal activity in it considerably reduced the amplitude of responses in the thalamo-cortical fibers. The first somatosensory area was much more effective than the second in this respect. The development of paroxysmal activity in the projection cortex also appreciably reduce after-inhibition in the posterior ventral nucleus, as shown by application of paired stimuli to the medial lemniscus.
