Previous working memory (WM) studies found that relative to controls, subjects with
cannabis use disorder (CUD) showed greater brain activation in some regions (eg, left [L]
and right [R] ventrolateral prefrontal cortex [VLPFC], and L dorsolateral prefrontal cortex [L-
DLPFC]), and lower activation in other regions (eg, R-DLPFC). In this study, effective
connectivity (EC) analysis was applied to functional magnetic resonance imaging data
acquired from 23 CUD subjects and 23 controls (two groups matched for sociodemographic …
