Intrinsically Photosensitive Retinal Ganglion Cells
Journal of Neuro-Ophthalmology, 2007 The recent discovery of melanopsin-expressing retinal ganglion cells that mediate the pupil light reflex has provided new insights into how the pupil responds to different properties of light. These ganglion cells are unique in their ability to transduce light into electrical energy.

Retinal Ganglion Cell Topography in Elasmobranchs
Brain, Behavior and Evolution, 2000Retinal wholemounts are used to examine the topographic distribution of retinal cells within the ganglion cell layer in a range of elasmobranchs from different depths. The retina is examined for regional specializations for acute vision in six species of selachians, <i>Galeocerdo cuvieri, Hemiscyllium ocellatum, Scyliorhinus canicula, Galeus ...

Purification and Culture of Retinal Ganglion Cells
Cold Spring Harbor Protocols, 2013Retinal ganglion cells (RGCs) are the neurons that extend axons through the optic nerve, connecting and transmitting information from the retina to the brain. In mammals, RGCs receive information from bipolar and amacrine cells and synapse onto target cells in the lateral geniculate nucleus (LGN) as well as the superior colliculus.

Current Biology
How do we perceive the beautiful and rich world around us? Light from the external environment is focused onto the retina, our visual sensory organ. Photons are captured by photoreceptors - light sensors within the retina - and converted into electrical signals. These electrical signals are transmitted to the brain through the optic nerve.

Variability in responses of retinal ganglion cells
Journal of the Optical Society of America A, 1988Changes in the maintained discharge of retinal ganglion cells have been modeled by addition of noise to a rate-setting signal, whereas the responses of cortical cells have been reported to indicate a nonlinear relationship between noise and signal. To determine whether this represents a difference between retinal cells and cortical cells, the variance ...

Hyperacuity in Cat Retinal Ganglion Cells
Science, 1986Cat X retinal ganglion cells that can resolve sine gratings of only 2.5 cycles per degree can nevertheless respond reliably to displacements of a grating of approximately 1 minute of arc. This is a form of hyperacuity comparable in magnitude to that seen in human vision.

Activation of autophagy in retinal ganglion cells
Journal of Neuroscience Research, 2008AbstractAutophagy has been shown to be activated in neuronal cells in response to injury and suggested to have a cell‐protective role in neurodegenerative diseases. In this study, we investigated the activation of autophagy in retinal ganglion cells (RGCs) following optic nerve transection (ONT) and evaluated its effect on RGC survival.

The autoregulation of retinal ganglion cell number
Development, 2001ABSTRACT The development of the nervous system is dependent on a complex set of signals whose precise co-ordination ensures that the correct number of neurones are generated. This regulation is achieved through a variety of cues that influence both the generation and the maintenance of neurones during development.

Culture of rat retinal ganglion cells
Journal of Huazhong University of Science and Technology [Medical Sciences], 2011This study aimed to modify the mixed and purified culture of rat retinal ganglion cells (RGCs) in vitro. The retinae of 1-3 day old Sprague-Dawley (SD) rats were separated bluntly into two layers: inner layer and outer layer, under a surgical microscope. Retinal cells isolated from different layers (inner layer, outer layer and whole retinal tissue) by

Topography of pig retinal ganglion cells
Journal of Comparative Neurology, 2005AbstractIn the present work we analyzed the distribution of retinal ganglion cells (RGCs) in the pig retina. RGCs were retrogradely labeled in vivo by injecting Fluoro‐Gold into the optic nerve. RGC density and the distribution of RGCs in terms of soma size were analyzed. Different regions of the porcine retina were identified following analysis of the
