  Binocular zone



Binocular zone

    The central region of the visual field from which light enter both eyes.

RELATED TERMS
--------------------------------------

Central
In anatomy and medicine (as elsewhere), central is the opposite of "peripheral" which means away from the center.



SIMILAR TERMS
--------------------------------------

Binocular
Using both eyes at the same time. Binocular vision is the most important element of depth perception.

Binocular diplopia
See: Diplopia, binocular.

Binocular disparity
The difference in position of two retinal images of an object that do not fall on exactly corresponding retinal positions.

Binocular field
A receptive field which responds to a cells optimal stimulus if it is presented to either eye.

Binocular overlap
The segment of the optic array sampled by both eyes.

Binocular rivalry
Occurs when the two eyes are presented with different stimuli. Instead of seeing a summation of the two images, our perception switches from one image to the other.

Binocular vision
Vision performed with two eyes/sensors whose outputs are often used to extract relative stereoscopic depth.

Binocularity
The ability to focus upon an object with both eyes and create a single stereoscopic image. Binocularity requires highly convergent orbits. The evolutionary increases among primates in the degree of orbital convergence have been noted to correlate with the expansion of visual brain structures and, as a consequence, with the overall size of the brain. It is therefore thought that the evolution of brain size in primates was associated with visual specialization.

Binoptic stimulation
When the same image is presented to each eye.

Bioluminescence
The emission of light by organisms.

Bipolar cell
Key interneurons in the retina. Antagonistic center-surround receptive field organization. Makes excitatory connections to ganglion cells.

Blind spot
The location where optic nerve fibers leave the retina. This area has no photoreceptors and therefore no visual input. The cortex appears to fill-in this missing information so we are not conscious of the blind spot.

Blindsight
A phenomenon reported in individuals suffering from cortical blindness (i.e. damage to the primary visual cortex resulting in blindness). Individuals with blindsight report that they are unable to see, yet under forced choice conditions are able to indicate the presence and location of visually presented objects.
