Interspike Interval Based Filtering of Directional Selective Retinal Ganglion Cells Spike Trains
(a) Color coded burst activity for each of the recorded cells. First four rows represent each of the 12 recorded ON-OFF DSRGCs since the last row stands for the three recorded ON DSRGCs. The color code represents the mean number of bursts per trial. For each square the axis depicts the burst category starting with first row as 2 spikes/burst followed by increasing number of spikes per burst up to the last category consisting in bursts with 10 spikes per burst. axis for each square represents the eight different stimulus directions of movement. (b) Left color map represents the mean burst activity for all 12 ON-OFF DSRGCs. axis represents the different burst categories in number of spikes/burst. axis represents the stimulus directions. Right color map represents the same for all 3 ON DSRGCs. (c) Mean number of bursts for each of the burst category (in number of spikes/burst) at preferred direction for all ON DSRGCs. (d) Mean number of bursts for each of the burst category (in number of spikes/burst) at preferred direction for all ON-OFF DSRGCs.
