Webb12 okt. 2024 · Interest in hippocampal sharp wave ripples (SPW-Rs) has accelerated over the past decade. SPW-Rs are highly conserved among mammals, but their presence in lizards and birds has been debated 1,2 ... 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. Multiple studies have now suggested that SWRs support the process of memory …

Sharp waves and ripples (SWRs) are oscillatory patterns produced by extremely synchronised activity of neurons in the mammalian hippocampus and neighbouring regions which occur spontaneously in idle waking states or during NREM sleep. They can be observed with a variety of imaging methods, such as EEG. … Visa mer Neuronal oscillations are important components of neuroscience research. During the last two decades, hippocampal oscillations have been a major focus in the research of neuronal oscillations. Among different oscillations … Visa mer Structures Circuit The trisynaptic loop, as the main circuit of the hippocampus … Visa mer In spite of the fact that hippocampal ripples (140–220 Hz) and fast gamma (90–150 Hz) oscillations have similar mechanisms of generation, they are two distinct patterns in … Visa mer • Hippocampus • Neural oscillation • Epilepsy • Sleep spindle Visa mer Sharp waves and associated ripples are present in the mammalian brains of the species that have been investigated for this purpose, including mice, rats, rabbits, monkeys and humans. In all of these species, they have been shown primarily to be involved in … Visa mer Epilepsy In addition to ongoing research on the role of SPW-R complexes in memory consolidation and neuronal plasticity, another major area … Visa mer • Buzsáki, György (2006).
