Abstract

A recent study by Buonomano et al. reports two important contributions; namely, empirical evidence for prediction error-like responses in single cells, using ex vivo preparations and optogenetics. Second, it foregrounds the role of asymmetric coupling in generating itinerant dynamics required for temporal prediction in neuronal circuits.
