Parasol cell
From Wikipedia, the free encyclopedia
A parasol cell, sometimes called an M cell[1] or M ganglion cell,[2] is one type of retinal ganglion cell (RGC) located in the ganglion cell layer of the retina. These cells project to magnocellular cells in the lateral geniculate nucleus (LGN) as part of the magnocellular pathway in the visual system.[3] They have large cell bodies as well as extensive branching dendrite networks and as such have large receptive fields.[4][3] Relative to other RGCs, they have fast conduction velocities.[4] While they do show clear center-surround antagonism (known as spatial opponency), they receive no information about color (absence of chromatic opponency).[3] Parasol ganglion cells contribute information about the motion and depth of objects to the visual system.[5]
