Follow your heart? Examining heart rate variability as a predictor of neural reactivity to social rejection - A network approach to individual differences in social threat sensitivity
Abstract:Frontal midline (FM) theta (4–8 Hz) reactivity to unexpected social rejection seems to be an important correlate of a neural threat-detection system. Neurovisceral integration theory proposes that the functioning of such systems is indexed by heart rate variability (HRV). Here, we tested this by examining whether baseline HRV predicts FM-theta reactivity to unexpected rejection feedback. Additionally, we examined whether this alleged heart-brain connection differs based on individual differences in personality… Show more
