Dissociation, cognitive conflict and nonlinear patterns of heart rate dynamics in patients with unipolar depression

Abstract

Recent findings in cognitive neuroscience indicate that activation of anterior cingulate cortex (ACC) is related to detecting cognitive conflict. Conflict related ACC activation elicits responses in central autonomic network which can be assessed by psychophysiological measures such as heart rate variability (i.e. beat to beat R-R intervals - RRI).
