Dimensions of interoception and their implications for psychopathology

Interoception is the process by which the nervous system senses, integrates and interprets internal bodily sensations, such as signals arising from the heart. Emotional feeling states are influenced by different levels of interoceptive processing. These levels encompass afferent, neural, behavioural accuracy and higher-order measures related to interoceptive judgments ascertained via subjective report. This talk will detail how these different interoceptive dimensions, at different levels of processing, can guide and shape cognition and emotion processing. The nature of afferent signals, their representation in brain, their precision and higher order representation are selectively altered in different clinical conditions, with implications for symptom expression.
