Anterior Cingulate The anterior cingulate is located in the dorsomedial prefron- tal cortex and is interconnected with other rostral limbic structures, including the amygdala and nucleus accumbens. Multiple roles of the anterior cingulate include selective at- tention and emotional reactivity to significant stimuli (75, 87). In parallel with the amygdala findings, the anterior cingulate was differentially activated during video-induced cocaine craving in our initial PET study with 15O bolus (by ROI analysis and later confirmation by SPM analysis of the group data) (Fig. As with the amyg- dala effect, the cue-induced rCBF increase in anterior cingu- late was from a resting baseline that was hypoactive relative to the baseline of controls. These studies used fMRI (84,86) and PET with 15O bolus (82), FIGURE110. Amygdala andanterior cingulateactivations dur- imaging techniques that provide good temporal resolution.

Much the same could be said ACTH must still be considered unproven (71).
