WebIn the visual system, receptive fields are volumes in visual space.They are smallest in the fovea where they can be a few minutes of arc like a dot on this page, to the whole page. … WebOff-center GCs are stimulated by surround stimuli, and inhibited by center stimuli. What is an on off-center surround receptive field? There are two primary types of ganglion cell receptive fields: ON center/OFF surround cell: Flashing small bright spot in the center subregion increases the cell’s response. … An OFF-center/ON-surround ...

WebA scientist has dissected out a small section of the retina and is able to directly record the action potential firing rate in a single ganglion cell. Assume there is a on-center off-surround bipolar cell connected to an on-center off-surround ganglion cell.

WebThe base rate for ganglion cell firing under uniform lighting conditions (i.e. equal stimulation of the center & surround) is ~20-50 action potentials per second, so you actually get a reduction in firing if the OFF-center cell is stimulated in the center, but an increase in firing if the ON-center cell is stimulated in the center. the longshots dvd
