The parvocellular pathway is one of the three primary visual pathways (magnocellular, parvocellular, and koniocellular pathways) traveling subcortically from the retina to visual cortex via the lateral geniculate nucleus (LGN). Cells in the parvocellular pathway (P pathway) are specialized for detecting color.

Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus. "Parvus" is Latin for "small", and the name "parvocellular" refers to the small size of the cell compared to the larger magnocellular cells. Phylogenetically, parvocellular neurons are more modern than magnocellular ones.

"WebWithin the nerves, different axons carry different qualities of the visual signal. Some axons constitute the magnocellular (big cell) pathway, which carries information about form, movement, depth, and differences in brightness. Other axons constitute the parvocellular (small cell) pathway, which carries information on color and fine detail. " - Magnocellular and parvocellular cells
