Magnocellular parts, also called M cells, are cells in the brain concerned primarily with visual perception. In particular these cells are responsible for resolving motion and coarse outlines. The cells have large, fast-conducting neurons and transmit information to the lateral geniculate nucleus, the area of the brain responsible for analyzing and interpreting the information. This system of cells operates with great speed at the expense of detail.
