Ocular dominance. 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]
Ocular dominance column. Ocular dominance columns are stripes of neurons in the visual cortex of certain mammals (including humans [ 1]) that respond preferentially to input from one eye or the other. [ 2] The columns span multiple cortical layers, and are laid out in a striped pattern across the surface of the striate cortex (V1).
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 ...
Those signals are processed in stacks of cells called ocular dominance columns, a checkerboard pattern of connections alternating between the left and right eye. A slight discrepancy in the ...
the thumb test is the easiest way to disprove the existence of ocular dominance, when you hold your thumb at arms length depending on whether your focusing on the object or your thumb, one will be doubled, that is non convergent. the lenses of your eyes will be focused at a different distance but it has no impact on the test. when you choose ...
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, connected by the corpus callosum.
Topographic map (neuroanatomy) In neuroanatomy, topographic map is the ordered projection of a sensory surface (like the retina or the skin) or an effector system (like the musculature) to one or more structures of the central nervous system. Topographic maps can be found in all sensory systems and in many motor systems .
Retinal waves. Retinal waves are spontaneous bursts of action potentials that propagate in a wave-like fashion across the developing retina. These waves occur before rod and cone maturation and before vision can occur. The signals from retinal waves drive the activity in the dorsal lateral geniculate nucleus (dLGN) and the primary visual cortex.
