  1. The correlation coefficients (r) (Spearman: above diagonal; Pearson: below diagonal) and the associated probabilities (p) are shown. Note: all correlations are based on the data of 32 animals except the correlations with 'PA log latency entry dark, retention', which are based on the data of 31 animals. Correlation coefficients with associated probabilities < 0.05 are printed bold.
