    <p>HCs showed more activation in the bilateral dorsolateral prefrontal cortex, right ventral lateral prefrontal cortex, and right anterior cingulate than PRGs. Results are depicted with a threshold of p<0.001 uncorrected. Colour bar represents corresponding T values.</p

    <p>PRGs showed more activation in the bilateral dorsolateral prefrontal cortex and right dorsal cingulate cortex than HCs. Results are depicted with a threshold of p<0.001 uncorrected to show the extent of the activation. Colour bar represents corresponding T values.</p

    <p>HCs = Healthy controls, PRGs = problematic gamblers, msec = milliseconds; ** = significant group difference at p<0.05; * = trend for group differences <i>p</i><0.10; Error bars represent the standard errors of the mean. B: Percentage of impulsive errors during Go/NoGo blocks. HCs = Healthy controls, PRGs = Problematic gamblers, ** = significant group difference at p<0.05; * = trend for group differences <i>p</i><0.10; Error bars represent the standard deviations of the mean.</p

    <p>The SRC consisted of two approach, avoid, and baseline blocks. Trials consisted of a cannabis or control image with a manikin left or right next to it. Approach-block instructions were to move the manikin towards cannabis images but away from other images. Avoid-block instructions were the reversed. The manikin could be moved left and right by pressing the corresponding left and right response box button. Baseline-block Instructions were to press left or right according to the manikin’s position.</p
