Modulation of the heartbeat evoked cortical potential by hypnotizability and hypnosis.

Hypnotizability is a psychophysiological trait measured by scales and associated with several differences, including interoceptive accuracy and the morpho-functional characteristics of interoception-related brain regions. The aim of the study was to assess whether the amplitude of the heartbeat evoked cortical potential (HEP), a correlate of interoceptive accuracy, differs in participants with low (lows) and high (highs) hypnotizability scores (assessed by the Stanford Hypnotic Susceptibility Scale, Form A) before and after the induction of hypnosis. ECG and EEG were monitored in 16 highs and 15 lows during an experimental session, including open eyes baseline (B), closed eyes relaxation (R), hypnotic induction (IND), neutral hypnosis (NH), and post session baseline (Post).

Well-Being in Highly Hypnotizable Persons.

Both hypnotizability and well-being are relevant to health. This study aimed to investigate whether high hypnotizability was positively associated with well-being and whether the latter was related to the activity of the behavioral inhibition/approach system (BIS/BAS). ANOVA revealed significantly higher scores on the General Well-Being Index (PGWBI) in highly hypnotizable (highs, = 31) compared with low hypnotizable participants (lows, = 53), with medium hypnotizable participants (mediums, = 41) exhibiting intermediate values.

Interoceptive Accuracy as a Function of Hypnotizability.

This study aimed to measure the interoceptive accuracy (IA) of individuals with high ), medium , and low hypnotizability through the heartbeat-counting task during 3 relaxation trials. Participants completed the Multidimensional Assessment of Interoceptive Awareness (MAIA), ECG and skin conductance (SC) were monitored, and the experienced difficulty in counting was reported. Results showed similar counting difficulty and number of actual heartbeats in highs, mediums, and lows.

Towards a psychopathology specific to Substance Use Disorder: Should emotional responses to life events be included?

Introduction: The severity of emotional responses to life events (PTSD spectrum) as part of Post Traumatic Stress Disorder (PTSD) in Substance Use Disorder (SUD) patients has often been considered from a unitary perspective. Light has also been shed on the possible definition of a specific psychopathology of SUD patients. This psychopathology has been proved to be independent of treatment choice, of being active in using substances, of lifetime psychiatric comorbidity and primary substance of abuse (heroin, alcohol, cocaine).
