The conference is the largest of its kind in the world, featuring more than 120 academic presentations biennially. Neurotransmissions spans the sciences and humanities, from philosophy and neuroscience though chemical models of action into clinical uses, with a special emphasis on MDMA. Cross-cultural approaches explore the use of psychedelics in New Guinea, Central and South America, British free festivals, electronic music and backwards in time to the ancient civilisations of India and Rome. The journey ends with an exploration of the role of psychedelics in artistic expression, spirituality and death. In the final chapter, Neurotransmissions presents the only published account of the world's first pure DMT trip.
