Intrinsic physiological properties of rat retinal ganglion cells with a comparative analysis.
Mammalian retina contains 15-20 different retinal ganglion cell (RGC) types, each of which is responsible for encoding different aspects of the visual scene. The encoding is defined by a combination of RGC synaptic inputs, the neurotransmitter systems used, and their intrinsic physiological properties. Each cell's intrinsic properties are defined by its morphology and membrane characteristics, ...
متن کاملHeterogeneous intrinsic firing properties of vertebrate retinal ganglion cells.
Retinal ganglion cells (RGCs) use their characteristic firing patterns to encode various aspects of visual information and carry them to the brain. It has been thought that the firing pattern of an RGC's light response is determined primarily by the time course and spatiotemporal interaction of the synaptic inputs. However, it is unclear whether there is a difference in intrinsic firing propert...
متن کاملMaturation of intrinsic membrane properties in rat retinal ganglion cells
In view of the prominent role of voltage-activated conductances in both neuronal differentiation and signal transmission, the present study describes developmental alterations of ion channel properties during the functional maturation of rat RGCs, i.e., between embryonic day 15 when RGCs start to differentiate (E15) and postnatal day 35 (P35) when the retina is fully developed and the animals h...

متن کاملContrast Sensitivity of Retinal Ganglion Cells of the Cat By
1. Spatial summation within cat retinal receptive fields was studied by recording from optic-tract fibres the responses of ganglion cells to grating patterns whose luminance perpendicular to the bars varied sinusoidally about the mean level. 2. Summation over the receptive fields of some cells (X-cells) was found to be approximately linear, while for other cells (Y-cells) summation was very non...
