“…Interesting findings of the study are that the dACC activity was decreased in the control group and increased in the alcoholic group despite the comparable level of subjective anger to standardized anger-induction stimuli. The greater dACC activation in the alcohol group relative to the control group is consistent with Park et al [ 31 ] in the evaluation of angry faces and feeling anger in the individuals with AUD college students [ 34 ]. The dACC is activated when participants are angered [ 28 ] and seems to be implicated in anger control [ 35 ].…”

BackgroundVery little is known about the neural circuitry underlying anger processing among alcoholics. The purpose of this study was to examine the altered brain activity of alcoholic individuals during transient anger emotion.MethodsUsing functional magnetic resonance imaging (fMRI), 18 male patients diagnosed with alcohol dependence in an inpatient alcohol treatment facility and 16 social drinkers with similar demographics were scanned during the viewing of anger-provoking film clips.ResultsWhile there was no significant difference in the level of experienced anger between alcohol-dependent patients and non-alcoholic controls, significantly greater activation was observed in the bilateral dorsal anterior cingulate cortex (dACC) and the right precentral gyrus among alcoholic patients compared to the normal controls.ConclusionsIn summary, specific brain regions were identified that are associated with anger among patients with alcohol dependency.
