The enhancement of edges in Mach bands can be explained by
A)lateral inhibition.
B)the activity of rods but not cones.
C)dark adaptation.

Question

Quizplus · Accepted Answer

Mach bands are the result of lateral inhibition in the visual system, which enhances the perception of edges by reducing the perception of neighboring areas. This phenomenon is thought to occur through inhibitory interneurons in the retina and visual cortex. Rods and cones are both involved in edge detection, and dark adaptation may enhance the sensitivity of the visual system to low light levels, but neither of these factors specifically explain the enhancement of edges in Mach bands.
