Working Overtime: Altered Functional Connectivity in Working Memory Following Regular Cannabis Use in Young Adults
There is an emerging consensus that regular cannabis use may be detrimental to the developing brain, including potential long-lasting changes in executive functioning. Consequently, the present study examined neural activation and performance on a working memory n-back task using functional magnetic resonance imaging (fMRI) in a sample of young adults (ages 19 to 21) from a longitudinal research sample. Regular cannabis users (n = 10) were compared with non-regular cannabis user controls (n = 14) while completing the letter n-back task during fMRI. While there were no differences across performance indices, imaging parameters showed significant differences in brain activation during task performance. Specifically, there wa
