What do improvisation, dreaming, and psychedelics have in common from a neuroscience perspective?

What is the experience of improvisation and what are its neurobiological correlates? One way to flesh out an answer, or at least to get the lay of the land, so to speak, is to look at how improvisation compares with other kinds of brain states and states of experience that have been explored with science, such as dreaming and psychedelics. That's what we're embarking upon here. In this video, you are going to discover that there are some quite interesting relationships between what's happening in the brain during improvisation and what happens to the brain under the influence of dreaming and classical psychedelics.
