Classification of turtle retinal ganglion cells
Journal of Neurophysiology, 19891. Receptive fields of 78 retinal ganglion cells were analyzed for their responses to moving and stationary lights that were presented under a variety of stimulus conditions. All cells were sensitive to moving stimuli, and their receptive fields often comprised excitatory and inhibitory sub-regions. 2.

Ganglion cells typically make up the innermost layer of the vertebrate retina. They are the only cells with axons that leave the eye. These axons form the optic nerve. Ganglion cell dendrites ramify in the inner nuclear layer, where they are postsynaptic to bipolar cells, which provide a direct input pathway from the outer plexiform layer, and to ...

Correlated firing of retinal ganglion cells
Trends in Neurosciences, 1989Even in the absence of visual stimulation, retinal ganglion cells have a substantial maintained discharge. This maintained discharge is not generated independently within each ganglion cell, because the unstimulated activity of two neighboring ganglion cells can be remarkably correlated.

The responses of the retinal ganglion cells of the frog
Vision Research, 1975Abstract Three groupsofunitswere recorded from theretinaof Rana esculenta . These were: (a)Units which responded to a square wave modulated light stimulus and these were of three types: ON units, ON-OFF units and OFF units. Stimulus-response curves for both a stimulating central spot and an annulus were constructed and the effects of increasing ...

Retinal Ganglion Cells and Neuroprotection for Glaucoma
Survey of Ophthalmology, 2003Neuroprotection is a therapeutic strategy directed at keeping retinal ganglion cells (RGCs) alive and functional. This article discusses three commonly asked questions about neuroprotection and attempts to answer them in the context of our current understanding of the pathophysiology of RGC loss in glaucomatous optic neuropathy.

'Refracting' a Single Retinal Ganglion Cell
Archives of Ophthalmology, 1971The response characteristics of retinal ganglion cells to focused and blurred imagery and three interdependent response criteria, measured at the ganglion cell level, are used for the neurophysiological estimate of refractive error.

Concerted Signaling by Retinal Ganglion Cells
Science, 1995To analyze the rules that govern communication between eye and brain, visual responses were recorded from an intact salamander retina. Parallel observation of many retinal ganglion cells with a microelectrode array showed that nearby neurons often fired synchronously, with spike delays of less than 10 milliseconds.

Diacylglycerol Signaling in Retinal Ganglion Cells
With impaired retinal ganglion cell (RGC) function and eventual RGC death, there is a heightened risk of experiencing glaucoma-induced blindness or other optic neuropathies. Poor RGC efficiency leads to limited transmission of visual signals between the retina and the brain by RGC axons.Ishan, Chaplot +3 more

The dynamics of primate M retinal ganglion cells
Visual Neuroscience, 1999The retinal ganglion cells (RGCs) of the primate form at least two classes—M and P—that differ fundamentally in their functional properties. M cells have temporal-frequency response characteristics distinct from P cells (Benardete et al., 1992; Lee et al., 1994). In this paper, we elaborate on the temporal-frequency responses of M cells and focus

Retinal Ganglion Cell Shrinkage in Glaucoma
Journal of Glaucoma, 2002There has been some debate concerning the selective loss of retinal ganglion cells belonging to the magnocellular pathway in early glaucoma. Although histologic studies of retinal ganglion cells in experimental and human glaucoma have suggested selective loss of the larger cells and, by implication, selective damage to the magnocellular pathway, this ...
