Figure 7. Multi-electrode array recordings from the retina 18 months after the viral injection. A: The raster plots consist of 180 consecutive light-elicited spike activities from a retinal ganglion cell during the course of a 3 h recording session. B: Sample light-evoked spikes were recorded at the beginning (top) and the end (bottom) of the recordings. C: The averaged spike rate was plotted versus the time. The duration of the light stimulation was 1 s and the interval between successive light stimuli was 60 s. The light intensity was 6.6×1016 photons cm−2s−1.
