Learning-induced plasticity regulates hippocampal sharp wave-ripple drive

G Girardeau, A Cei, M Zugaro - Journal of Neuroscience, 2014 - Soc Neuroscience
Hippocampal sharp wave-ripples (SPW-Rs) and associated place-cell reactivations are
crucial for spatial memory consolidation during sleep and rest. However, it remains unclear …

Sharp-wave ripples orchestrate the induction of synaptic plasticity during reactivation of place cell firing patterns in the hippocampus

JHLP Sadowski, MW Jones, JR Mellor - Cell reports, 2016 - cell.com
Place cell firing patterns reactivated during hippocampal sharp-wave ripples (SWRs) in rest

Optogenetically blocking sharp wave ripple events in sleep does not interfere with the formation of stable spatial representation in the CA1 area of the hippocampus

KA Kovács, J O'Neill, P Schoenenberger, M Penttonen… - PloS one, 2016 - journals.plos.org
During hippocampal sharp wave/ripple (SWR) events, previously occurring, sensory input-
driven neuronal firing patterns are replayed. Such replay is thought to be important for …

Hippocampal sharp wave/ripples during sleep for consolidation of associative memory

W Ramadan, O Eschenko, SJ Sara - PloS one, 2009 - journals.plos.org
The beneficial effect of sleep on memory has been well-established by extensive research
on humans, but the neurophysiological mechanisms remain a matter of speculation. This …

Hippocampal sharp wave-ripples and the associated sequence replay emerge from structured synaptic interactions in a network model of area CA3

A Ecker, B Bagi, E Vértes, O Steinbach-Németh… - Elife, 2022 - elifesciences.org
Hippocampal place cells are activated sequentially as an animal explores its environment.
These activity sequences are internally recreated ('replayed'), either in the same or reversed …

High-frequency oscillations, known as sharp-wave/ripple (SPW-R) complexes occurring in
hippocampus during slow-wave sleep (SWS), have been proposed to promote synaptic …

Hippocampal-prefrontal reactivation during learning is stronger in awake compared with sleep states

W Tang, JD Shin, LM Frank… - Journal of Neuroscience, 2017 - Soc Neuroscience
Hippocampal sharp-wave ripple (SWR) events occur during both behavior (awake SWRs)
and slow-wave sleep (sleep SWRs). Awake and sleep SWRs both contribute to spatial …

Hippocampal–cortical coupling differentiates long-term memory processes

P Dahal, OJ Rauhala, D Khodagholy… - Proceedings of the …, 2023 - National Acad Sciences
