“…Typically, the anterior insula has been associated with that function, including risk prediction, 37 but the posterior insula tracks changes of interoceptive states and somatosensory processes. 38 This is of interest and importance for anorexia nervosa research because of the disorder's (ill or recovered) association with distorted body perception that has been linked to the insula among other brain regions, 39,40 reduced pain perception that has been linked to the posterior insula, 41,42 reduced interoception measured by heart rate detection tasks, 43 and the altered drive to eat. Thus, altered activation in the posterior insula could be a potentially important marker for altered pathophysiology in individuals recovered from anorexia nervosa; however, this needs further study.…”
