Abstract
Recent experimental and clinical studies1 on the "premotor area," i. e., the region of the cerebral cortex just anterior to the classic "motor area," indicate that this region is intimately concerned with motor activity and that it probably gives rise to important motor projection systems. As statements in the literature concerning the electrical excitability of this area lack precision and, indeed, are often conflicting, it has seemed desirable to carry out a carefully controlled analysis of the response of this region to faradic stimulation, before and after the removal of the motor area, and to correlate the results with detailed microscopic examination of the cortex. The present paper embraces the results of such a study. The terms "motor" and "premotor" areas have been used throughout as synonymous, respectively, with "area 4" and "area 6" of Brodmann.
