fMRI linear mixed effects results for the group (low THC-OSU, high THC-OSU, low THC-CS) by decision (win risky vs. win safe) interaction (n = 120).

Cluster significance of p < .05 corrected for multiple comparisons (voxel-wise probability: p < .05, F2,117 = 3.07). Abbreviations: R, right; L, left; x, y and z: Brodmann Area (BA) coordinates; ACC, anterior cingulate cortex; SFG, superior frontal gyrus; negative, negative correlation between lifetime use and BOLD; positive, positive correlation between lifetime use and BOLD. 1 Whole brain analysis. fMRI linear mixed effects results for the group (low THC-OSU, high THC-OSU, low THC-CS) by decision (win risky vs. win safe) interaction (n = 120).
