Mapping immersive states of consciousness: DMT and the human brain  Christopher Timmermann-Slater (Centre for Psychedelic Research, Department of Medicine, Centre for Psychiatry, Imperial College, London, United Kingdom)   PL3

N,N-Dimethyltryptamine (DMT) provides an opportunity to determine the neuronal underpinnings of radical shifts in conscious experience. Its subjective effects are characterised by strong bodily and visual effects leading to a subjective feeling of immersion in a different 'space' and disconnection from the immediate environment, in similar fashion to dreaming. I will present empirical results of studies in which DMT has been administered to healthy participants while multimodal brain imaging (EEG-fMRI) and phenomenological data was collected using a second-person neurophenomenological approach, which will illustrate some of the mechanisms underpinning the DMT state and its implications for consciousness research.
