The Science Behind Psychedelic Substances

Today on Hempire Eileen is joined by Draulio B. de Araujo-Ph.D of Universidade Federal do Rio Grande. Draulio works as a professor of neuroscience at the Brain Institute in Natal, Brazil. His interests are related to the science behind psychedelic substances, such as ayahuasca, including recent randomized trials to test its antidepressant potential. They speak about how the en tropic brain hypothesis holds that the key facts concerning psychedelics are partially explained in terms of increased entropy of the brain’s functional connectivity.

Ayahuasca is a psychedelic beverage of Amazonian indigenous origin with legal status in Brazil in religious and scientific settings. In this context, he uses tools and concepts from the theory of complex networks to analyze resting state fMRI data of the brains of human subjects under two distinct conditions, under ordinary waking state and in an altered state of consciousness induced by ingestion of Ayahuasca.
