ABSTRACT
Hypnotizability, as measured by standardized scales, accounts for part of the variability of the general population in several domains. This chapter reviews genetic markers (catechol-O-methyltransferase, oxytocin, opioid receptor µ1, fatty acid amide hydrolase) and hypnotizability-related correlates observed in the ordinary state of consciousness in sensori-motor integration (spinal and trigeminal reflexes, postural and visuomotor control, motor cortex excitability, functional equivalence between imagery and perception/action, cerebellar morpho-functional characteristics) and cardiovascular control (heart rate and variability, heartbeat perception, peripheral arteries post occlusion flow-mediated dilation, cerebrovascular reactivity, and neurovascular coupling). The reported findings indicate that hypnotizability plays a role in everyday life, supports the bio-psycho-social model of hypnotic behavior, and suggests an evolutionary perspective of hypnotizability.
