Visual properties of human retinal ganglion cells

Example response properties of human ganglion cells.
A) ON-cells, B) OFF-cells, C) ON-OFF-cells. Column 1: average firing rates (top) and raster plots (bottom) to full-field contrast steps; column 2: response to bar moving with different speeds; column 3: activity during a full-field chirp contrast ramp at 2 Hz; column 4: response to “chirp stimulus” (full-field temporal frequency modulation from 0.5 to 8 Hz); column 5: normalized response strengths to 24 sinusoidal drifting-gratings (convention as in Fig 1B); column 6: firing rate for the sinusoidal drifting-grating causing maximal response (black square in column 5). Stimuli are depicted on top. Colors correspond to Fig 5. Empty space indicates that the stimulus was not presented to this cell. Firing rates plotted in gray indicate that this cell did not respond consistently to this stimulus.
