10 of 15
There was a strong connection between the PCC (posterior cingulate cortex) and the BDS (bilateral dorsal striatum) - r=+0.5, and the BI (bilateral insula) - r=+0.6, which demonstrates a significant positive correlation. What does this suggest?
The longer the participant had been addicted, the stronger these connections were
