Colour-coded arrows show how the P, M and W layers of the lateral geniculate nucleus … WebThe results suggest that a system involved in the processing of color information, especially color-spatial interactions, runs parallel to and separate from the orientation-specific system. Staining for the mitochondrial enzyme cytochrome oxidase reveals an array of dense regions (blobs) in the primate primary visual cortex. They are most obvious in the upper …
WebInterblobs are areas between blobs which receive the same input, but are sensitive to orientation instead of color. They output to the pale and thick stripes of area V2. Blobs are on the parvocellular pathway. This pathway begins at the photoreceptors which then … WebNeurons in the blobs are involved in color perception, while neurons in the interblobs participate in processing form and motion. In the secondary visual cortex (BA 18) …
