Significant correlations between regional frontostriatal and medial temporal lobe volumes and episodic verbal memory performance in the Parkinson’s group

Regions	Learning	Long Delay Free Recall	Long Delay Cued Recall	Recognition Memory Hits	Recognition Memory False Positives
Frontostriatal System
R Pars triangularis			0.33a	0.35a
Medial Temporal System
R Entorhinal	0.39a
R Parahippocampus	0.44b	0.34a	0.33a	0.33a
R Hippocampus	0.37b		0.39b		−0.40b
L Temporal Pole	0.36a

Only memory indices that exhibited significant correlations with brain volumes are displayed. Pearson correlation coefficients are reported, except for recognition memory hits and false positives, which are Spearman correlation coefficients. R = right hemisphere; L = left hemisphere.
