The enhancement of contrast at the edge of an object is primarily due to lateral inhibition by the:

Question

Quizplus · Accepted Answer

Lateral inhibition is a process where the activity of neurons decreases the activity of neighboring neurons. Horizontal cells are involved in lateral inhibition in the retina, and they can enhance the contrast at the edge of an object by decreasing the activity of the neurons in the surrounding area. This helps to sharpen the perception of edges and boundaries. Rods and cones are photoreceptor cells, and bipolar cells are intermediate neurons that transmit signals from photoreceptors to ganglion cells. While these cells are important in vision, they are not directly involved in lateral inhibition.
