There is wide variability in ganglion cell types across species. There is strong evidence that the retinal ganglion cell theory is untenable. It consists of over one million retinal ganglion cell axons. Her research focuses on the retinal ganglion cell. However, Neurostatin successfully inhibited activation of astrocytes, in turn decreasing retinal ganglion cell death significantly. The eye pathology is limited to the retinal ganglion cell layer especially the maculopapillary bundle. Several photoreceptors may send their information to one ganglion cell. The first action potential occurs in the retinal ganglion cell. The optic nerve is composed of retinal ganglion cell axons and glial cells. A midget cell is one type of retinal ganglion cell (RGC). This inhibits the release of neurotransmitters from the bipolar cells to the ganglion cell. This allows each retinal ganglion cell to recognize its proper termination site. In 2007, a new role was found for the photoreceptive ganglion cell. Red light stimulates the red cone, which in turn stimulates the red/green ganglion cell. A ganglion cell is a cell found in a ganglion.
