Direct visualization of the dendritic and receptive fields of directionally selective retinal ganglion cells

G Yang and RH Masland

Program in Neuroscience, Harvard Medical School, Massachusetts General Hospital, Boston 02114.

Optical methods were used to locate the cell bodies of directionally selective ganglion cells in isolated rabbit retinas. These neurons detect the direction in which images move across the retinal surface and transmit that information to the brain. The receptive field of each identified cell was determined, after which the cell was injected with Lucifer yellow. An image of the receptive field border was then projected onto the fluorescent image of the dendrites, allowing precise comparison between them. The size of the receptive field matched closely the size of the dendritic arbor of that cell. This result restricts the types of convergence that can be postulated in modeling the mechanism of retinal directional selectivity.
