Perception of stabilized retinal stimuli in dichoptic viewing conditions. 1982

G I Rozhkova, and P P Nickolayev, and V E Shchadrin

Perception of stabilized retinal stimuli was studied both in monocular and dichoptic viewing conditions. When identical stabilized stimuli of large size and high luminance were presented to both eyes, the phenomena characteristic of monocular perception (rapid fading of perceived images within a few seconds or their episodic disappearance and regeneration) failed to be observed: the visual images were perceived as decaying only gradually and slowly within several minutes. The results suggest that rapid changes and fluctuations of visual images perceived monocularly may be due to the effects of binocular interaction (cooperation/rivalry), episodic darkenings of the visual field seeming to be caused by temporary predominance of the occluded eye.

D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D003118	Color Perception	Mental processing of chromatic signals (COLOR VISION) from the eye by the VISUAL CORTEX where they are converted into symbolic representations. Color perception involves numerous neurons, and is influenced not only by the distribution of wavelengths from the viewed object, but also by its background color and brightness contrast at its boundary.
