The secret life of predictive brains: what's spontaneous activity for?

G Pezzulo, M Zorzi, M Corbetta - Trends in cognitive sciences, 2021 - cell.com
Brains at rest generate dynamical activity that is highly structured in space and time. We
suggest that spontaneous activity, as in rest or dreaming, underlies top-down dynamics of …
