In the retina, an excited neural receptor can suppress the activity of surrounding neurons within an area called the inhibitory field. This effect, known as [[lateral inhibition]], increases the contrast and sharpness in visual response, but leads to the epiphenomenon of [[Mach bands]]. This is often illustrated by the [[illusion|optical illusion]] of light or dark stripes next to a sharp boundary between two regions in an image of different luminance.
