It is a controversial question whether hypnosis can be regarded as a specific state of consciousness with neuropsychological and neurophysiological correlates. Previously responses to suggestions in hypnosis were explained by invoking an altered state of consciousness, typically referred to as a trance, but because of the consistent failure to identify typical markers of this altered state many researchers turned to social-cognitive approaches. It has been stated that there are two basic issues that divide the research field: The first is "trance versus nontrance" and the second is "persistent individual differences versus experimental manipulation". After 25 years of continuous research similar issues still divide the scientific field. However during this period hypnosis has matured as a relevant topic in psychological research as well as a technique for clinical application.

The aim of this project is to stress the importance of bringing hypnosis research into neuroscience. Hypnosis as a method for enhancing the scope of subjective experiences is a valuable tool when studying how human feeling, thought and experience arise from brain activity.
