Widespread ripples synchronize human cortical activity during sleep, waking, and memory recall
Declarative memory encoding, consolidation, and retrieval require the integration of
elements encoded in widespread cortical locations. The mechanism whereby such “binding” …

Modeling sharp wave‐ripple complexes through a CA3‐CA1 network model with chemical synapses
The hippocampus, and particularly the CA3 and CA1 areas, exhibit a variety of oscillatory
rhythms that span frequencies from the slow theta range (4–10 Hz) up to fast ripples (˜ 200 …
