Summary
By recording primary responses in two cortical areas of the pudendal nerve, afferent fibers have been shown to run to the cortex of each cerebral hemisphere. The focus of maximal activity (FMA) of the first zone, i.e., the cortical area within which the primary responses occur at maximum amplitude and minimum latent period is usually located on the posterior cruciate gyrus. The FMA of the second zone is located on the anterior ectosylvian gyrus. Both zones lie in the area reptesenting the hindlimb. The cortical areas of the pudendal and pelvic nerves discovered previously by the present author overlap each other widely, though their FMA do not coincide. This signifies that for each of the nerves, within the boundaries of the common area in which primary responses occur, there is a small area in which maximum values are obtained.
