Definition
Magno-, parvo-, and koniocellular pathways are the three visual pathways in primates. These pathways are established at the level of the lateral geniculate nucleus (LGN) of the thalamus. They are formed of morphologically distinct cellular layers that receive information from different types of retinal ganglion cells and project to different layers in the primary visual cortex.
Anatomical Considerations
The LGN layers of each of the three visual pathways have a specific cytoarchitectonic structure. The 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, 5,...
