Magnitude of task-induced deactivation of insula and anterior cingulate cortex is related to inter-individual differences in RMSSD

Abstract

By combining functional Magnetic Resonance Imaging and acquisition of cardiac pulsation during the execution of a cognitive task we identified areas where task-induced changes in brain activity correlated with individuals' cardiac RMSSD. We show the existence of a relationship between task - induced deactivations and RMSSD.
