Bistratified cell
Encyclopedia
A small-field bistratified cell, or just bistratified cell, is a retinal ganglion cell whose cell body is located in the ganglion cell layer
of the retina
. Bistratified cells receive their input from bipolar cells and amacrine cell
s. The bistratified cells project their axons through the optic nerve
and optic tract
to the koniocellular layers in the lateral geniculate nucleus
(LGN), synapsing with koniocellular cells. Koniocellular means “cells as small as dust”; their small size made them hard to find. About 8 to 10% of retinal ganglion cells are bistratified cells. They receive inputs from intermediate numbers of rods and cones. They have moderate spatial resolution, moderate conduction velocity, and can respond to moderate-contrast stimuli. They may be involved in color vision. They have very large receptive fields that only have centers (no surrounds) and are always ON to the blue cone and OFF to both the red and green cone.
Ganglion cell layer
The ganglion cell layer is a layer of the retina that consists of retinal ganglion cells.In the macula lutea, the layer forms several strata....
of the retina
Retina
The vertebrate retina is a light-sensitive tissue lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina, which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical...
. Bistratified cells receive their input from bipolar cells and amacrine cell
Amacrine cell
Amacrine cells are interneurons in the retina. Amacrine cells are responsible for 70% of input to retinal ganglion cells. Bipolar cells, which are responsible for the other 30% of input to retinal ganglia, are regulated by amacrine cells.-Overview:...
s. The bistratified cells project their axons through the optic nerve
Optic nerve
The optic nerve, also called cranial nerve 2, transmits visual information from the retina to the brain. Derived from the embryonic retinal ganglion cell, a diverticulum located in the diencephalon, the optic nerve doesn't regenerate after transection.-Anatomy:The optic nerve is the second of...
and optic tract
Optic tract
The optic tract is a part of the visual system in the brain.It is a continuation of the optic nerve and runs from the optic chiasm to the lateral geniculate nucleus....

Lateral geniculate nucleus
The lateral geniculate nucleus is the primary relay center for visual information received from the retina of the eye. The LGN is found inside the thalamus of the brain....
