Horizontal cells

Horizontal cells Cells in the retina connected via gap junctions that mediate lateral information transfer over large distances.
RELATED TERMS--------------------------------------
Retina
A membrane lining the inside of the back of the eye that contains light-sensitive nerve cells that convert focused light into nerve impulses, making vision possible.
Lateral
Toward the side, sideways.
SIMILAR TERMS--------------------------------------

PREVIOUS AND NEXT TERMS--------------------------------------
Hysteroscopy
A procedure in which a doctor uses an endoscope to examine the health of the uterus.
Half-Wave rectification
A signal which follows only the positive part of a sinusoid and has zero-response to the negative part. Many simple cells show half-wave rectification to contrast reversing patterns.
Haploscopic stimulation
Different stimuli for the two eyes.
Hemineglect
A condition following damage to the parietal stream of one hemisphere in which individuals are unaware of stimuli from the hemifield that projects to that hemisphere.
Hollow face illusion
A concave hollow mask of a face viewed from a few feet gives the impression of a normal face. The cognitive interpretation overrides the stereoscopic information.
Horizontal cells
Horopter
For a given fixation point, the set of points on the retina that are perceived to have zero retinal disparity. The points sweep out an arc in space that intersects a fixated point in space.
Hue
The perception of color.
Hyperacuity
Psychophysical tasks involving judgements of relative position that are about ten times finer than the separation of bars at the grating acuity limit.
Hypercolumn
A set of columns in the primary visual cortex (V1) that contains columns responsive to lines of all orientations from a particular region of space and for both eyes.
Hypercomplex cells
A third category of striate cells identified by Hubel and Wiesel that have since been classified as subsets of simple and complex cells. They posses inhibitory zones at one or both ends of oriented excitatory regions, thereby responding to bars of preferred orientation only if they are not too long.
