The Entropic Brain

This episode was largely based on a paper entitled “The entropic brain: a theory of conscious states informed by neuroimaging research with psychedelic drugs” Carhart-Harris et al. (David Nutt) (2014) https://www.frontiersin.org/articles/10.3389/fnhum.2014.00020/full#B80

Figure: Summary of the entropic brain hypothesis, depicting different states of consciousness based on their level of system disorder or uncertainty. Primary states, on the left, have high entropy and are flexible, whereas subcritical states, on the right, have low entropy and are rigid. Taken from Carhart-Harris et al. (2014)
