WebNov 13, 2024 · Introduction. Hippocampal sharp-wave ripples (SPW-Rs) are one of the most synchronous spontaneous population patterns in the mammalian brain. They represent a complex event, composed of the sharp wave, a large-amplitude negative polarity deflection (40–-120 ms) in CA1 apical dendrites, and a short-lived fast oscillatory pattern … WebEquipped with sticky sharp treble hooks and premium components, anglers will appreciate improved hook-up ratios and long-lasting performance. Finished with realistic 3D eyes, … 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.
