The neuronal basis for motion detection

Visual motion processing takes place mainly in the Magnocellular pathway, a hierarchy composed of the M-type (Parasol) ganglion cells in the retina, the two ventral M-type layers in the LGN, the 4 $C_{\alpha}$ and 4B layers in V1, and the extrastriate middle temporal area (MT), and the medial superior temporal area (MST). These cortical areas form the so called where or dorsal pathway (in contrast to the what or ventral pathway leading to the interiotemporal lobe).
