Average latency (A), reference errors (B), working memory (WM) errors (C) and the percentage of spatial strategy used (D) on the second day of reversal learning trials in the Barnes maze test. TAT+ mice (gray bars) took less time, and made fewer reference and working memory errors compared with TAT- control mice (white bars). TAT+ mice treated with saline (grey, non-hatched bar) utilised a spatial strategy on a greater percentage of trials compared with TAT- control mice treated with saline (white, non-hatched bar; D). Selegiline treatment tended to increase spatial strategy use in TAT- control mice and decrease spatial strategy use in TAT+ mice. *p < 0.05, **p < 0.01, ***p < 0.001.
