Quanta Magazine | What Your Brain Is Really Doing When You're Doing 'Nothing' @QuantaScienceChannel | Uploaded August 2024 | Updated October 2024, 1 hour ago.
When your mind is wandering, your brain’s “default mode” network (DMN) is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other. New research, including a recent study of the brain on psilocybin, is revealing the default mode networks's role in memory, social awareness and sense of self.
