Gait movements caused by excitation of a point deep in the cerebral cortex of the dog

Abstract

The brief electric excitation of a point situated in the caudal wall of the sulcus presilvius determines in the dog the appearance of walking movements of the forelegs, lasting from 10-15 minutes. The concurrence of central and peripheric factors in the keeping up of these movements is shown.

Excitation of the gyrus orbitalis produces a transitory inhibition of the mentioned walking movements which sets the problem of the existence in area 13 of an inhibitory action which may influence several other central functions.
