D) inhibition of ganglion cells by bipolar cells

Question

Quizplus · Accepted Answer

Brightness contrast is the effect where the perceived brightness of an object is affected by the brightness of its surroundings. This effect is attributed to lateral inhibition, which occurs when the neurons in the retina inhibit their neighbors, enhancing the contrast between light and dark regions in the visual field. The inhibition of the neurons creates a sharpening of the boundary between light and dark regions, resulting in an increased perception of contrast.
