K-complex consists of a brief negative high-voltage peak, usually greater than 100 μV, followed by a slower positive complex around 350 and 550 ms and at 900 ms a final negative peak. K …

2023年5月1日 · The K-Complex is a waveform identified on electroencephalography (EEG), which primarily occurs during Stage 2 (N2) of NREM sleep, along with sleep spindles, which make …

2023年9月7日 · N2 sleep is a complex stage of sleep with many functions, from memory consolidation to protection of the sleep state. The physiological changes that occur during N2 …

…waves, which are also called K-complexes, are induced by external stimulation (e.g., a sound) or occur spontaneously during sleep. Sleep spindles and spontaneous K-complexes are …

The K-complex can be observed during stage 2, 3, and 4 sleep but is usually absent during paradoxical or rapid eye movement (REM) sleep. Like other electrophysiologic potentials, it …

2023年8月12日 · Discover the physiology of the K complex, a distinctive sleep waveform, and its role in sleep protection, memory consolidation, and sleep stage transitions. Learn about the …

1997年10月1日 · The K-complex is a major graphoelement of sleep EEG. This report demonstrates that K-complexes emerge from a cortically generated slow (≤1-Hz) oscillation.

2002年5月1日 · This paper summarizes the present knowledge about the cellular bases of the sleep K-complex (KC). The KC has two phases: the initial surface-positive wave is due to the …

This paper summarizes the present knowledge about the cellular bases of the sleep K-complex (KC). The KC has two phases: the initial surface-positive wave is due to the synchronous …

The K-complex (KC) is a sharp, well-delineated, high-voltage, biphasic wave that lasts for more than 0.5 seconds and has been termed as the largest event in a healthy human EEG.
