DARK ADAPTATION IN THE CAT: STUDY OF VISUAL PERCEPTION IN HUMANS AND ANIMALS.
Abstract
The time course of dark adaptation in the cat was investigated by a behavioral tracking procedure. Pupil size during light adaptation was found to influence the time course of dark adaptation significantly. The dark adaptation process was much more rapid following light adaptation with the natural pupil than was the case with the pupil artificially dilated. Dark adaptation curves for test stimuli of various wavelengths showed a time course for cone and rod processes not unlike those found for humans but differing from curves reported in an electrophysiological study of single retinal ganglion cells.
