Welcome to The International Hypnosis Research Institute Web site. Our intention is to support and promote the further worldwide integration of comprehensive evidence-based research and clinical hypnotherapy with mainstream mental health, medicine, and coaching. We do so by disseminating, supporting, and conducting research, providing professional level education, advocating increased level of practitioner competency, and supporting the viability and success of clinical practitioners. Although currently over 80% of our membership is comprised of mental health practitioners, we fully recognize the role, support, involvement, and needs of those in the medical and coaching fields. This site is not intended as a source of medical or psychological advice. Tim Brunson, PhD

Cerebral blood flow evaluation during the hypnotic state with transcranial Doppler sonography.

Cerebral blood flow was measured in normal waking (alert relaxed mental imagery) and hypnotic states. Mean flow velocity (Vm) in the middle cerebral artery (MCA) was significantly increased in hypnosis (Condition II) from Condition I (5 minutes before hypnotic induction). Vm decreased in Condition III (hypnotic imagination). After hypnosis, Vm values returned to baseline. Pulsatility index values and resistive index values showed significant variations during sonographic monitoring between Conditions I and IV (5 minutes after the completion of hypnosis). Both values were significantly higher in Condition I than IV. These findings show that hypnotic status can modulate cerebral blood flow.
