This webinar is dedicated to the memory of ALIUS founder Martin Fortier-Davy and features Chris Timmermann, Enzo Tagliazucchi, Katrin Preller, and Raphaël Millière. Each of these researchers use their own set of innovative methods to study the diversity of consciousness. Whether it’s through amassing and analyzing big data sets, scanning the brains of volunteers who are given psychedelics intravenously in laboratory settings, or using specialized interview techniques such as microphenomenology, these researchers all try to capture what it’s like to be in an altered state of consciousness. how this can help us to understand the nature of consciousness, and how we can use this knowledge to improve mental health.
