Selective sensitivity to direction of movement in ganglion cells of the rabbit retina.
نویسندگان
چکیده
Among the ganglion cells in the rabbit's retina there is a class that responds to movement of a stimulus in one direction, and does not respond to movement in the opposite direction. The same directional selectivity holds over the whole receptive field of one such cell, but the selected direction differs in different cells. The discharge is almost uninfluenced by the intensity of the stimulus spot, and the response occurs for the same direction of movement when a black spot is substituted for a light spot.

Simulation of movement detection by direction-selective ganglion cells in the rabbit and squirrel retina.
A veto-gate model of movement detection by direction-selective ganglion cells in the vertebrate retina, first proposed by Barlow and Levick (1965), provides the basis for a model described in this study. The model is a simple network consisting basically of (1) two subunits that have receptive fields with a center-surround organization and an adaptational gain control, (2) a lateral inhibitory ...
متن کاملPhysiological properties of direction-selective ganglion cells in early postnatal and adult mouse retina.
Selective responses of retinal ganglion cells (RGCs) to the direction of motion have been recorded extracellularly from the rabbit and the mouse retina at eye opening. Recently, it has been shown that the development of this circuitry is light independent. Using whole-cell patch clamp recording, we report here that mouse early postnatal direction-selective ganglion cells (DSGCs) showed lower me...
متن کاملExpression of Nicotinic Acetylcholine Receptor α4 and β2 Subunits on Direction-Selective Retinal Ganglion Cells in the Rabbit
The direction selectivity of the retina is a distinct mechanism that is critical function of eyes for survival. The direction-selective retinal ganglion cells (DS RGCs) strongly respond to a preferred direction, but rarely respond to opposite direction or null directional visual stimuli. The DS RGCs are sensitive to acetylcholine, which is secreted from starburst amacrine cells (SACs) to the DS...
متن کاملDirection-selective units in rabbit retina: distribution of preferred directions.
The preferred directions of 102 direction-selective ganglion cells in the rabbit retina have been determined. Cells of the "on-off" type form four nonoverlapping groups; cells of the "on" type fall into three groups. The on-off groups appear to correspond to the directions of apparent object displacement produced by contractions of the four rectus muscles. Each group of cells could, without fur...
متن کاملIdentification of ON-OFF direction-selective ganglion cells in the mouse retina.
We identified the ON-OFF direction-selective ganglion cells (DSGCs) in the mouse retina and characterized their physiological, morphological and pharmacological properties. These cells showed transient responses to the onset and termination of a stationary flashing spot, and strong directional selectivity to a moving rectangle. Application of various pharmacological reagents demonstrated that t...
