A microelectrode inserted into a cat retinal ganglion cell of the "ON" cell type described by Kuffler would
A) show a change in response rate to rapid movements of a dark spot.
B) record an excitatory burst of potentials to a light placed within a circular center.
C) record a decreased number of potentials to a light placed within a circular center.
D) show an increased number of potentials when a light was placed onto a ring surrounding the center.
E) result in random action potentials.

Question

Quizplus · Accepted Answer

Kuffler described "ON" cells as cells that fire more action potentials in response to light stimuli placed in their center compared to the surrounding area. Therefore, a microelectrode inserted into a retinal ganglion cell of the "ON" cell type would record an excitatory burst of potentials to a light placed within a circular center.
