Reconstruction error for increasing number of ganglion cells. (A – E) The mean of the root mean square error (RMSE) for stimulus reconstruction with relative latencies was calculated for each experiment with random choice of increasing number of units. The reconstruction error decreased monotonically in all experiments but experiment 5, where error remained high (E). Especially experiment 2 with the highest number of recorded cells (n = 32) yielded a very low error of 4.72 m/s. (F) When calculating the mean RMSE with increasing number of all 109 ganglion cells from all 5 experiments, the error approached zero. n = 18 in (A); n = 32 in (B); n = 19 in (C); n = 26 in (E); n = 14 in (E), total n = 109 (F).
