| summary | Fast strong heartbeats change the ways we think, feel and act. The expression and experience of emotions is supported by physiological changes within the body, mediated in part by efferent autonomic and afferent viscerosensory nerves. Correspondingly, brain regions implicated in the processing of motivational salience and affective representations are coupled to the control of internal physiological state.
We are defining how interoceptive signals concerning physiological arousal (notably, those signals encoding the timing and strength of individual heartbeats) influence the perception of environmental stimuli and evoked behavioural, emotional and cognitive responses. These insights are complemented by an enhanced understanding of individual differences in dimensions of interoceptive processing [1] and of the neural mechanisms through which mind, brain and body interact to influence subjective experience and behaviour. Recent work in our lab has focused on the effects of heartbeat signals on the processing of fear and threat [2]. Potential implications for ‘high-cost decision-making’ will be illustrated [3, 4].
