Medial prefrontal and anterior cingulate cortical response to drug cues was positively correlated with the number of XRNTX injections received. Statistical map (red–yellow scale) is displayed over the MNI brain template and thresholded at z=2.3 (cluster corrected at P<0.05). MNI, Montreal Neurological Institute; XRNTX, injectable extended-release naltrexone.
