WebA critical prerequisite for memory consolidation is precise coordination of reactivation events between the hippocampus and cortical/subcortical structures, facilitated by the coupling of local field potential (LFP) oscillations (slow oscillations, sleep spindles and sharp wave/ripples) between these structures. We review the rapidly expanding ... WebFeb 11, 2015 · Hippocampal sharp-wave-associated ripple (SWR) oscillations (∼140–200 Hz) are the largest recorded brain signals of physiological significance (Buzsáki et al., 1992). Spontaneous SWRs occur as 50–100 ms epochs during slow-wave sleep (SWS), awake immobility, and consummatory behaviors like eating, drinking, and rearing. city of brantford garbage pickup https://tanybiz.com
