What are Sleep Spindles? - Sleep Foundation
2023年10月23日 · The term sleep spindles refers to a specific pattern of brain waves that occurs during sleep. Sleep spindles are identified by electroencephalography (EEG), which measures electrical activity in the brain.
Sleep spindle - Wikipedia
Sleep spindles are bursts of neural oscillatory activity that are generated by interplay of the thalamic reticular nucleus (TRN) and other thalamic nuclei during stage 2 NREM sleep in a frequency range of ~11 to 16 Hz (usually 12–14 Hz) with a duration of 0.5 seconds or greater (usually 0.5–1.5 seconds). [1][2][3] After generation as an ...
Sleep Spindles: Definition and Importance - Sleep Advisor
2024年6月18日 · Sleep spindles are bursts of brain activity that typically occur during Stage 2 of Non-Rapid Eye Movement (NREM) sleep. They are recorded by an Electroencephalogram (EEG), a device used to track and assess neurological patterns.
Sleep Spindles: Mechanisms and Functions
Sleep spindles refer to a well recognizable, burstlike sequence of 10–15 Hz sinusoidal cycles in the electroencephalogram (EEG) of sleeping mammals. The name stems from the envelope of a sleep spindle waveform that resembles the shape of the wool-spinning device.
Sleep Spindles: What Are They and When Do They Appear? - Sleep …
2024年2月1日 · Sleep spindles occur during non-rapid eye movement (NREM) sleep and are most prominent in the second stage of NREM sleep, which makes up between 45% and 55% of sleep in most adults. Sleep disorders, medical issues, aging, and the use of some medications can all affect a person’s sleep spindles.
Sleep Spindles: Mechanisms and Functions - PubMed
2020年4月1日 · We review the characteristics, organization, regulation, and origins of sleep spindles and their implication in non-rapid-eye-movement sleep (NREMS) and its functions, focusing on human and rodent.
Sleep Spindles in Humans: Insights from Intracranial EEG and Unit ...
Sleep spindles are an electroencephalographic (EEG) hallmark of non-rapid eye movement (NREM) sleep and are believed to mediate many sleep-related functions, from memory consolidation to cortical development.
Sleep spindles: Current Biology - Cell Press
2018年10月8日 · Sleep spindles are isolated bursts of oscillatory neural activity in the frequency range between 11 and 16 Hz, observed during non-rapid eye movement (NREM) sleep. They owe their name to a spindle-like shape, characterized by a progressively waxing, then gradually waning amplitude (Figure 1).
Sleep Spindles: Where They Come From, What They Do
2013年8月27日 · Sleep spindles are extensively studied electroencephalographic rhythms that recur periodically during non–rapid eye movement sleep and that are associated with rhythmic discharges of neurons throughout the thalamocortical system.
N2 Sleep: K Complexes and Sleep Spindles - Sleepopolis
2023年9月7日 · Sleep spindles and K complexes are brief bursts of activity visible on electroencephalogram, or EEG, during N2 sleep. Sleep spindles and K complexes are unique to non-REM sleep , and occur with greatest frequency during N2 sleep.
