Parvocellular vs magnocellular pathways
WebThe magnocellular pathway is one of the three primary subcortical pathways (magnocellular, parvocellular, and koniocellular pathways) leading from the retina to visual cortex via the lateral geniculate nucleus (LGN). Cells in the magnocellular pathway (M pathway) are specialized for detecting contrast sensitivity, course features, and … WebMost of the retinal cells in the parvocellular stream are P cells which are mainly cones (high-light vision, foveal, color sensitive, and high spatial acuity), and most retinal cells in the...
Parvocellular vs magnocellular pathways

WebThe magnocellular pathway carries information about large, fast things (low spatial frequency, high temporal frequency) and is colorblind. The parvocellular pathway carries information about small, slow, colorful things (high spatial frequency, low temporal … WebThe names of the pathways are derived from these structural characteristics. Magnocellular (M) cells have relatively large bodies (lat. Magnus: large) and are found in the lowest two layers (layers 1 and 2) of the LGN. Parvocellular (P) cells have smaller bodies (lat. Parvus: small) and are found in the top four layers of the LGN (layers 3, 4 ...
