On the Adversive Movement of Area 4C of the Motor Cortex

1. Adversive movements were induced by electrical stimulation and metrazol injection on area 4c of the cerebral cortex. 2. The adversive movement from area 4c does not pass through the thalamus, nucleus caudatus, nucleus lenticularis or superior collicuIus, but through direct efferent pathways in the internal capsule. 3. The adversive movement from area 4c passes through the pyramidal tract.
