COMPARISON OF PROPERTIES OF GOLDFISH RETINAL GANGLION-CELLS AS A FUNCTION OF LIGHTING CONDITIONS DURING DISSECTION

Recordings of action potentials were made from single ganglion cells in the isolated retinas of goldfish; retinas were dissected from the eye either in normal room lights or under dim red illumination. Cells from retinas isolated in normal lighting were usually not spectrally opponent, having a sensitivity dominated by the long wavelength sensitive cones; rod input to these cells could not be demonstrated. Cells from retinas isolated in dim red light, on the other hand, commonly were spectrally opponent and generally had demonstrable rod input. Other properties of the cells from retinas isolated under either lighting condition were the same. © 1979.
