Stroke Induces a BDNF-Dependent Improvement in Cognitive Flexibility in Aged Mice

Figure 3

Survival curve of the number of sessions each animal is required to make to reach the criterion (≥80% accuracy across two consecutive days) in the reversal (a) or rereversal (b) tasks. Aged animals (sham—dotted blue line; stroke—solid blue line) take longer to learn both tasks compared to young animals (sham—dotted red line; stroke—solid red line). Aged stroke animals performed better than aged sham controls.
