摘要：

The miniature swine (Sus scrofa) is a desirable model for certain electrophysiological studies because of its large brain, ready availability and low cost. We report our findings regarding the location of the auditory and somatosensory cortices obtained by cortical surface evoked potential mapping. Data were collected from 11 animals under general endotracheal anesthesia. Consistent positive potentials were obtained for both auditory (P24) and median nerve somatosensory (P26) stimulation. The auditory region was centered around the lateral (sylvian) fissure; the somatosensory region was centered around the central (dorsomedial suprasylvian) fissure. In the miniature swine the locations of the auditory and somatosensory cortices are comparable to those found in other species. © 1990.
