Updating the physiology of hypnotizability: Cerebellum and insula.

This chapter describes the physiological correlates of hypnotizability associated with the morpho-functional aspects of the cerebellum and insula, which are brain structures neglected in physiological research on hypnotizability. Both structures are involved in sensorimotor and interoceptive networks that play a cooperative role in sensorimotor and cognitive-emotional control. Hypnotizability-related cerebellar and insular characteristics may underlie observed differences in postural and visuomotor control, motor cortex excitability, functional equivalence between actual and imagined perception/action, detection and interpretation of bodily signals, emotional regulation, sense of agency, and body ownership. The reported findings highlight the relevance of mind-body interaction in everyday life and provide further insight into the complex networks involved in hypnotizability-related experience and behavior.
