What is responsible for sharpening contrast at visual borders?
A) Receptive fields
B) Lateral inhibition
C) Retinal disparity
D) The direction in which the light shines

Question

Quizplus · Accepted Answer

Lateral inhibition is responsible for sharpening contrast at visual borders by reducing the activity in neighbouring cells, thus enhancing the contrast at the border between areas of different light intensity. Receptive fields are a component of the visual system, but are not responsible for sharpening contrast. Retinal disparity is important for depth perception, but not for contrast enhancement. The direction of light shining does not affect the process of contrast enhancement.
