FIGURE 6.

Learning performance in the 5 Choice Reaction Time task in EXP1. Learning curves of control and STZ-treated animals are depicted. Shaded areas show the 95% confidence band of the fitted sigmoidal regression curves (thin [red] lines). The column chart inset shows the number of days taken to reach the maximum stage. Means ± SEM values are shown. No significant difference was detected either between the learning curves or in the days elapsed until reaching the final stage (unpaired t-test: t(15) = 0.25, ns).
