A retinal ganglion cell (RGC) is a type of neuron located near the inner surface (the ganglion cell layer) of the retina of the eye. It receives visual information from photoreceptors via two intermediate neuron types: bipolar cells and retina amacrine cells .
Examples of ganglion cells include: Retinal ganglion cell (RGC) found in the ganglion cell layer of the retina [1] Cells that reside in the adrenal medulla, where they are involved in the sympathetic nervous system's release of epinephrine and norepinephrine into the blood stream; Cells of the sympathetic ganglia; Cells of the parasympathetic ...
Overview of the retina photoreceptors. ipRGCs labelled at the top-right. Intrinsically photosensitive retinal ganglion cells (ipRGCs), also called photosensitive retinal ganglion cells (pRGC), or melanopsin-containing retinal ganglion cells (mRGCs), are a type of neuron in the retina of the mammalian eye.
The axons of midget cells travel through the optic nerve and optic tract, ultimately synapsing with parvocellular cells in the LGN. These cells are known as midget retinal ganglion cells due to the small sizes of their dendritic trees and cell bodies. About 80% of RGCs are midget cells. They receive inputs from relatively few rods and cones.
Bistratified cell or bistratified ganglion cell can refer to either of two kinds of retinal ganglion cells whose cell body is located in the ganglion cell layer of the retina: the small bistratified cell (SBC), also known as small-field bistratified ganglion cell; the large bistratified cell (LBC) or large-field bistratified ganglion cell [1 ...
In the anatomy of the eye, the ganglion cell layer (ganglionic layer) is a layer of the retina that consists of retinal ganglion cells and displaced amacrine cells. The cells are somewhat flask -shaped; the rounded internal surface of each resting on the stratum opticum , and sending off an axon which is prolonged into it.
Retinal ganglion cell axons collectively form the optic nerve, via which they project to the brain. [ 8 ] The rod and cone photoreceptors signal their absorption of photons via a decrease in the release of the neurotransmitter glutamate to bipolar cells at its axon terminal.
Giant retinal ganglion cells contain a photo-pigment, melanopsin, allowing them to respond directly to light. They also receive connections from rods and cones, allowing them to encode colour and spatial information. Dacey et al. found the giants' receptive field sizes to be about three times the diameter of those of parasol ganglion cells.
