Stereo-deficients and stereoblinds cannot make utrocular discriminations. 1985

R Barbeito, and D Levi, and S Klein, and D Loshin, and H Ono

In two separate experiments, we show that stereo-deficient observers are no better than stereonormals at discriminating the eye-of-origin of a monocular stimulation. Stereo-deficient observers are considered to have a preponderance of monocular neurons throughout their visual system, including the visual cortex. The results indicate that, in spite of their clear anatomical and physiological structure, such monocular neurons do not convey eye-of-origin information to consciousness.

D010468	Perceptual Disorders	Cognitive disorders characterized by an impaired ability to perceive the nature of objects or concepts through use of the sense organs. These include spatial neglect syndromes, where an individual does not attend to visual, auditory, or sensory stimuli presented from one side of the body.

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
