A model showing how neural coherence can flexibly route information.  If you have a better idea of what underlies cognitive flexibility, I’d like to hear it.

Flexible information routing by transient synchrony

Andre Bastos and colleagues review an update the communication-through-coherence (CTC) hypothesis.  They propose that bi-directional cortical communication involves separate feedforward and feedback mechanisms that are separate both anatomically and spectrally.
