Question

Quizplus · Accepted Answer

Mach bands are an illusion that occurs due to lateral inhibition among adjacent neurons in the visual system. In this case, the darker area sends less lateral inhibition to the lighter area than the lighter area sends to the darker area, which amplifies the contrast between the two areas and creates the illusion of a band of increased intensity at the edge. So, the answer is A, i.e., less.

In Mach Bands, the Darker Area Sends _____ Lateral Inhibition
