WebAug 16, 2024 · Hippocampal ripples ( 1, 2) are brief (<150 ms) high-frequency oscillatory events, in the range of 140 to 200 Hz in rodents ( 3 – 6) and 80 to 140 Hz in primates and humans ( 7 – 11 ), that appear in the local field potential (LFP) of the hippocampal CA1 pyramidal layer ( 3, 5 ). Conserved across a variety of species, these short-lived ... WebJan 4, 2024 · Hippocampal sharp wave ripples (SPW-R) have been identified as key bio-markers of important brain functions such as memory consolidation and decision making. Understanding their underlying mechanisms in healthy and pathological brain function and behaviour rely on accurate SPW-R detection. In this multidisciplinary study, we propose … 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.
