Document Summary
6 eye specific layers no interaction between layers: layers 1, 4, Layers 1, 2 receive input from m-cells, white layers 3, 4, 5, 6 receive information from p-cells: magno-, parvo- and koniocell layers: magnocellular cells get the information from rods, they are rapid, transient, color-insensitive and movement-sensitive. Parvocellular cells get the information from cones, they are slow, sustained and color-sensitive. Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans) that respond preferentially to input from one eye or the other. Orientation columns are organized regions of neurons in the primary visual cortex that are excited by visual line stimuli of varying angles. Blobs are sections of the visual cortex where groups of neurons that are sensitive to color assemble in cylindrical shapes. Bilateral lesion of the parietal lobe leads to a behavioral deficit in a task that requires the discrimination of locations.
