Abstract
Objective
Processing of positive emotions in depressed individuals is different from healthy ones but its physiological correlates especially during different levels of consciousness is not yet well-understood. This study investigated physiological correlates of emotional processing of positive emotions during hypnosis and consciousness in depressed individuals compared to healthy control with the electroencephalogram (EEG).
Method
Forty individuals classified in two groups of depression (N = 20, 10 females) and healthy control (N = 20, 10 females) participated in this study. Participants in each group underwent a positive emotional experience during hypnotic state and conscious state while their EEG pattern was recorded. The EEG power was analyzed for both groups during hypnosis and conscious state.
Results
Results showed that experience of happiness significantly changed EEG pattern compared to the resting state in both groups with a significant increase in the Beta band in the right hemisphere. However, the increase in the right temporal beta activity was significantly higher in healthy subjects compared to depressed ones. Furthermore, the experience of happiness was not significantly different during hypnotic and conscious states in both groups. A significant increase in the Alpha band was also observed in both groups during hypnotic experience but not conscious state.
Conclusions
Electrophysiological processing of happiness is not different during hypnosis and consciousness but is associated with an increase of Beta band in the right temporal hemisphere in both depression and healthy subjects.
期刊介绍：
Neurology, Psychiatry & Brain Research publishes original papers and reviews in
biological psychiatry,
brain research,
neurology,
neuropsychiatry,
neuropsychoimmunology,
psychopathology,
psychotherapy.
The journal has a focus on international and interdisciplinary basic research with clinical relevance. Translational research is particularly appreciated. Authors are allowed to submit their manuscript in their native language as supplemental data to the English version.
Neurology, Psychiatry & Brain Research is related to the oldest German speaking journal in this field, the Centralblatt fur Nervenheilkunde, Psychiatrie und gerichtliche Psychopathologie, founded in 1878. The tradition and idea of previous famous editors (Alois Alzheimer and Kurt Schneider among others) was continued in modernized form with Neurology, Psychiatry & Brain Research. Centralblatt was a journal of broad scope and relevance, now Neurology, Psychiatry & Brain Research represents a journal with translational and interdisciplinary perspective, focusing on clinically oriented research in psychiatry, neurology and neighboring fields of neurosciences and psychology/psychotherapy with a preference for biologically oriented research including basic research. Preference is given for papers from newly emerging fields, like clinical psychoimmunology/neuroimmunology, and ideas.
