Global waves synchronize the brain's functional systems with fluctuating arousal
We propose and empirically support a parsimonious account of intrinsic, brain-wide
spatiotemporal organization arising from traveling waves linked to arousal. We hypothesize …

Spatiotemporal patterns of neocortical activity around hippocampal sharp-wave ripples
J Karimi Abadchi, M Nazari-Ahangarkolaee, S Gattas… - elife, 2020 - elifesciences.org
A prevalent model is that sharp-wave ripples (SWR) arise 'spontaneously'in CA3 and
propagate recent memory traces outward to the neocortex to facilitate memory consolidation …
