This is accomplished by the magnocellular pathway, which is responsible for processing information about movement. Finally, the visual system is important for color perception. This is accomplished by the cone cells, which are sensitive to different wavelengths of light.

WebVisual processing is mainly classified into two pathways, including the magnocellular pathway and parvocellular pathway (Skottun, 2015). The magnocellular pathway is mainly formed by large neurons, which project the visual stimuli to the visual dorsal, and is mainly involved with the location and motion of the stimulus.
