What goes on at the neurobiological level that makes someone more vulnerable to self-injure or self-harm? What biological risk factors are at play? What roles do the vagus nerve, cortisol levels, and hypothalamic-pituitary-adrenal (HPA) axis have? We hope to discuss the psychology of self-injury pain in a future episode, but in this episode, Dr. Michael Kaess from the University of Bern in Switzerland explains the neurobiology of self-injury in simple terms, or what we hope can be considered simple layman's terms. 

Learn more about Dr. Kaess and his research team at the Universitäre Psychiatrische Dienste (UPD) in Bern here.
