Visual Receptive Fields of Cells in a Cortical Area remote from the Striate Cortex in the Cat

Abstract

SEVERAL workers1–4 have reported that responses evoked either by light flash or by shock applied to the optic nerve can be recorded from a region of the suprasylvian gyrus (SSG) of the cat. These responses are similar in latency and waveform to those evoked from the primary visual area. Recent studies using the Nauta method have shown that degeneration appears in the medial wall of the suprasylvian sulcus after lesions in various parts of the visual pathway, including the lateral geniculate nucleus (LGN) (ref. 5), striate and peristriate cortex6,7. The band of degeneration is separated from visual area III by a degeneration-free zone along the apex of the suprasylvian gyrus. The experiments reported here were designed to analyse the specificity of response to visual stimuli of single neurones in the medial wall of the suprasylvian sulcus.
