What physiological mechanism produces brightness contrast?
A) mach bands
B) lateral inhibition
C) receptive field excitation
D) inhibition of ganglion cells by bipolar cells

Question

Quizplus · Accepted Answer

Lateral inhibition is a physiological mechanism that produces brightness contrast. It occurs when cells in the visual system inhibit the activity of nearby cells, leading to a sharpening of the boundaries between different regions of light and dark. This can create the perception of brightness contrast, where regions that are adjacent to each other appear to be brighter or darker than they would otherwise be.
