Document Summary
Psych 2e03 lecture 29 colour perception. The koniocellular layer in the lgn receives input from which retinal ganglion cells, to which lgn layers: bistratisfied cells, lgn layers 1-6. A complete understanding of colour processing in visual cortex remains elusive. Does not occur often in daily life. Only present in area v1, not lower. Can be both excited and inhibited in one portion of the receptive field by different chromatic stimuli. Their receptive field organization permits an isoluminant grating to have a reinforcing excitatory effect through both the centre and the surround, resulting in a strong neural response (bottom panel) Where are they in v1: high concentration of double opponent neurons in the blobs in layers 2/3 of area v1. Functional connection between blobs and interblobs arrange to make pale stripes and. Thin/thick stripes : systematic connection that"s very well observed. V2 connects to v4 and further connections are made to the temporal lobe: temporal lobe is in dorsal pathway.
