โœฆ Synopsis

We combined visual stimulation of the corticogeniculate pathway with cryogenic blockade of area 17 to examine the visual spatial structure of the cortical influence on single macaque LGN cells. Excitatory central areas surrounded by inhibitory regions and vice versa were found with equal frequency. Unstructured influences were also seen. The structure of the influence suggests that modulation of the spatial parameter may be an important function for the corticogeniculate pathway.

Recent publications have demonstrated a projection of the lateral geniculate nucleus (LGN) onto extrastriate cortical regions in the old world monkey but have failed to identify a projection from this nucleus to V2, the area adjacent to the striate cortex.
