Fig. 2.

The latency and average peak firing rates of visual responses before and after eye opening are illustrated for On and Off cells (top), as well as for On–Off cells (bottom). Both latencies and average firing rates were significantly different before and after eye opening (*p < 0.05, two-tailed ttest), with responsiveness increasing after eye opening. For all cell types, the latencies of the Off responses were significantly longer than those of the On responses (+p < 0.05, two-tailed t test).
