He completed two versions of his powerful film “Neurons to Nirvana” in 2013. The film consists mainly of short interview segments with many leading figures in the entheogenic medicine field, masterfully woven together into an engaging whole. Neurons to Nirvana will be shown at the conference at 7 pm on Saturday and will be followed by a panel discussion moderated by Oliver, with guests Dennis McKenna, Gillian Maxwell, Evgenia Fotiou, and Andrew Feldmár. Dennis, Gillian, and Andrew are also in the film.
