Figure 2.
Retinal neurons respond strongly to flicker stimulation. A, Single-unit recordings from RGCs reveal a transient increase in firing rate when the confocal imaging laser is turned on (filled rectangle at bottom), and a sustained increase in firing during flicker stimulation (open rectangle; mean of 19 cells, 5 eyecups). B, ERG recording shows no response when the confocal imaging laser is turned on (filled rectangle at bottom) and a large response to flicker stimulation (open rectangle).
