Fig. 3. Each pair of plots was computed as shown in Fig. 2J,K. `Same' is the average of Fig. 2J between patch 1 at t combined with patch 1 at t–t and patch 2 at t combined with patch 2 at –t. `Different' is the average of Fig. 2K between patch 1 at t combined with patch 2 at t–t and patch 2 at t combined with patch 1 at t–t. Six pairs are shown for six different cells (identity indicated by white labels). Notice that directional labeling on axes differs across neuronal types, reflecting differences in directional preference. For N values, see Materials and methods.
