Webb17 feb. 2024 · Normal hippocampal memory function relies on a variety of electrophysiological phenomena, perhaps the most notable of which are sharp wave ripples (SWRs) ( Buzsáki, 2015 ). The spectrum of SWR oscillations spans from the γ (30-80 Hz) to the ripple band (100-250 Hz). During SWRs, excitatory neurons and GABAergic …
Webbcampal sharp-wave ripples cooperatively act (dialog) in a precise timing for memory consol-idation. … WebbSharp wave ripples (SPW-Rs) represent the most synchronous population pattern in the mammalian brain. Their excitatory output affects a wide area of the cortex and several subcortical nuclei. SPW-Rs occur during "off-line" states of the brain, associated with consummatory behaviors and non-REM sleep …
Webb20 mars 2024 · Sharpwave ripples (SWRs) are oscillatory patterns seen in the hippocampus (HPC) local field potential (LFP) during offline periods such as awake immobility and sleep and are associated with highly synchronous neural firing in the HPC.
