Abstract

Experiments show that there are limiting delay times between the exposures of test stimuli to one eye and then to the other, beyond which stereoscopic depth perception does not occur. In the present experiments these limiting delay times are determined under photopic conditions in several different ways, principally for variations in exposure times. The limiting delay times are used in a model to define a duration of cortical excitations in those areas of the cortex where stimuli from the two eyes are received and utilized for stereoscopic depth perception. The minimal limiting delay measured from the beginning of the exposure to one eye to the beginning of the exposure to the other eye (equivalent to duration of cortical excitation) was about 100 msec. This limiting delay then increased, slowly at first, with increase of exposure time up to about 250 msec. Increased luminance of test stimuli reduced the limiting delay times, but repetitive exposures increased these times, as would be expected.

  11. One cannot be sure that these continuing excitations are indeed cortical and not retinal. If retinal, then excitations must be received continuously at the cortical level during the retinal persistence time. However, the fleeting manner in which stereoscopic depth is perceived from afterimages leads one to guess that the excitations dealt with here are probably cortical. If these excitations are indeed "on" and "off" phenomena, then stereoscopic depth can only result from an "on" (or an "off") effect for both eyes, but not from an "on" response from one eye and an "off" response from the other.
