While recording from a bipolar cell with a center-off surround-on receptive field,you observe a hyperpolarization in your cell.The stimulus that most likely triggered this response is light that covered
A) the surround,but not the center.
B) the center,but not the surround.
C) half of the center and half of the surround.
D) the entire receptive field.

Question

Quizplus · Accepted Answer

A center-off surround-on receptive field means that the cell responds with increased firing rate to light in the surrounding area and decreased firing rate (inhibition) to light in the center. Therefore, covering the center with light (option B) would lead to inhibition and hyperpolarization of the bipolar cell.
