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 … 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 responsible for information transfer … 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 the hippocampus. They are both produced as the response of the CA1 region to inputs … Visa mer • Buzsáki, György (2006). Rhythms of the brain. New York: Oxford Univ. Press. pp. 344–349. ISBN 978-0-19-982823-4. 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 … 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 • Hippocampus • Neural oscillation • Epilepsy • Sleep spindle Visa mer 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 aug. 2014 · Replay of neuronal activity during hippocampal sharp wave-ripples (SWRs) is essential in memory formation. To understand the mechanisms underlying the initiation of irregularly occurring SWRs and the generation of periodic ripples, we selectively manipulated different components of the CA3 network in mouse hippocampal slices.

Webb11 aug. 2024 · SPW-Rs are composed of a sharp wave, arising from neurons in the CA3 region of the hippocampus, that brings about a fast but localized network oscillation — … Webb20 apr. 2024 · 尖波涟漪（Sharp wave ripples，SPW-R）是海马在慢波睡眠过程中所呈现的一种场电位形式。 先前的研究发现其是学习和记忆巩固的基础。 在SPW-R中，携带着replay的各种信息，然后将短时记忆转化为长程记忆。 因此，可以说SPW-R是海马记忆巩固的核心工作方式，近些年来关于SPW-R的研究颇多，可见其重要性。 在最近的一 …
Webb8 feb. 2024 · Sharp wave and ripple events are transient high-frequency field oscillations that occur spontaneously during slow-wave sleep in the brain. Norimoto et al. found that these events induced long-term depression of hippocampal synapses and may thus help to refine recently acquired memories (see the Perspective by Draguhn).
