An in-class test of the opponent process theory of color vision relied on a basic principle of neurophysiology to explain color afterimages. What is this basic principle? O If a cell is excited or inhibited for a long period of time by a strong stimulus, when the stimulus is terminated the cell will temporarily "undershoot" or "overshoot" its normal activity rate. Receptor cells are able to respond to a wide variety of sensory inputs, but sensory neurons are only able to respond to a select few types of inputs. Sensory receptors are the first cells to process incoming stimuli, while sensory neurons have to rely on input from receptors in order to function. Retinal ganglion cells act in a non-intuitive "opposite" fashion, being inhibited by a strong stimulus, but excited by a weak stimulus.
