Blob (visual system)

Information about Blob (visual system)

Blobs are sections of the visual cortex where groups of neurons which are sensitive to color assemble in cylindrical shapes. They were first identified in 1979 by Margaret Wong-Riley when she used a cytochrome oxidase stain, from which they get their name.[1] These areas receive input from parvocellular cells in layer 4Cβ of the primary visual cortex and output to the thin strips of area V2. Interblobs are areas between blobs which receive the same input, but are sensitive to orientation instead of color. They output to the pale strips of area V2.

Eyes are organs of vision that detect light. Different kinds of light-sensitive organs are found in a variety of organisms. The simplest eyes do nothing but detect whether the surroundings are light or dark, while more complex eyes can distinguish shapes and colors.

The optic chiasm (Greek χίασμα, "crossing", from the Greek χλαζειν 'to mark with an X', after the Greek letter 'Χ', chi) is the part of the brain where the optic nerves partially cross.

The optic tract is a part of the visual system in the brain.

It is a continuation of the optic nerve and runs from the optic chiasm (where half of the information from each eye crosses sides, and half stays on the same side) to the lateral geniculate nucleus.
