“Performance” is the percentage of nose-pokes into the rewarded hole of the cognition wall. Performance line plots (E, F, H, I) display the mean performance over a 30 nose-poke rolling window. (A) Mean daily distances traveled. Grey shaded area indicates the three days of irradiation. (B) Distances travelled across the 6-day post-irradiation period normalized to the total on the day before irradiation. (C) Food pellets consumed per day across the 6-day post-irradiation period. (D) Correlation between VWRA and food consumption for each group and for the combined data. (E) Mean performance cumulative over the first night of reversal learning. *p < 0.05, ***p < 0.0005.
