Encyclopedia > 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 firs 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. This article is in need of attention from an expert on the subject. ... Parvocellular can refer to: Parvocellular part part of the Paraventricular nucleus Category: ... Brodmann area 17 (primary visual cortex) is shown in red in this image which also shows area 18 (orange) and 19 (yellow) The primary visual cortex (usually called V1) is the most well-studied visual area in the brain. ... Brodmann area 17 (primary visual cortex) is shown in red in this image which also shows area 18 (orange) and 19 (yellow) The visual cortex refers to the primary visual cortex (also known as striate cortex or V1) and extrastriate visual cortical areas such as V2, V3, V4, and V5. ...
