All regional brain volumes (cm³) corrected for height. WMv, WMnv, Gf are standardized scores with mean 0 and SD 1. Train, Repeated and Novel are identification thresholds. LPFC – lateral prefrontal cortex; OFC – orbitalfrontal cortex; Fwh – prefrontal white matter; HC – hippocampus; Cd – caudate; FG – fusiform gyrus, VC – primary visual cortex; WMv – standardized composite of verbal working memory tests; WMnv – standardized composite of nonverbal working memory tests; Gf – fluid intelligence composite; Repeated – repetition priming; Novel – skill learning.
