Ocular dominance, sometimes called eye preference or eyedness, [ 1] is the tendency to prefer visual input from one eye to the other. [ 2] It is somewhat analogous to the laterality of right- or left- handedness; however, the side of the dominant eye and the dominant hand do not always match. [ 3] This is because both hemispheres control both ...
A simulation of the ocular dominance column pattern, as might be seen if the surface of V1 were colored according to eye preference. A typical map of the relationship between ocular dominance, orientation, and cytochrome oxidase. Dark and light areas represent neurons that respond preferentially to the left and right eye.
Left cerebral hemisphere. The lateralization of brain function (or hemispheric dominance[ 1][ 2] / latralisation [ 3][ 4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres ...
Principle of binocular vision with horopter shown. In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and ...
Neuroanatomy of handedness. An estimated 90% of the world's human population consider themselves to be right-handed. [ 1] The human brain's control of motor function is a mirror image in terms of connectivity; the left hemisphere controls the right hand and vice versa. This theoretically means that the hemisphere contralateral to the dominant ...
The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. Other functions include maintaining the circadian rhythm, and keeping balance . Arizona Eye Model. "A" is accommodation in diopters. The eye can be considered as a living optical device. It is approximately spherical in shape, with its outer ...
Bias against people who are left-handed includes handwriting, which is one of the biggest sources of disadvantage for left-handed people, other than for those forced to work with certain machinery. About 90 percent of the world's population is right-handed, [ 1] and many common articles are designed for efficient use by right-handed people, and ...
Ambidexterity. Ambidexterity is the ability to use both the right and left hand equally well. [ 1][ 2] When referring to objects, the term indicates that the object is equally suitable for right-handed and left-handed people. When referring to humans, it indicates that a person has no marked preference for the use of the right or left hand .
