Parvo and magno cells
Did you know?
Magnocellular cells, also called M-cells, are neurons located within the magnocellular layer of the lateral geniculate nucleus of the thalamus. The cells are part of the visual system. They are termed "magnocellular" since they are characterized by their relatively large size compared to parvocellular cells.

WebThe magno cells are known to derive their inputs from a distinctive class of ganglion cells which derive their inputs from relatively larger areas of the retina than those ganglion cells which provide input for the parvo cells in the same general region of the retina. There are 8–10 times as many parvo cells than magno cells. WebNov 28, 2024 · The most common types of ganglion cells are magno and parvo. Magno cells process information about luminance, motion, stereopsis and depth of objects since they receive information from all cones and can quickly conduct this information (about 40 m/s). Parvo cells are slower (20 m/s), more numerous than magno (80% of total …
