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 …

Propagation of hippocampal ripples to the neocortex by way of a subiculum-retrosplenial pathway

N Nitzan, S McKenzie, P Beed, DF English… - Nature …, 2020 - nature.com
Bouts of high frequency activity known as sharp wave ripples (SPW-Rs) facilitate
