WebON-OFF CELLS. neurons within the visual system, specifically the retina, which depolarize whenever the retina is aroused with either light onset or light offset. ON-OFF CELLS: "On-off cells work solely with the retina and no other ocular areas." Cite this page: N., Sam M.S., "ON-OFF CELLS," in PsychologyDictionary.org, April 7, 2013, https ... WebRetinal ganglion cells (RGCs) are the bridging neurons that connect the retinal input to the visual processing centres within the central nervous system. There is a remarkable diversity of RGCs and the various subtypes have unique morphological features, distinct functions, and characteristic pathways linking the inner retina to the relevant brain areas.
