A K-complex is a waveform that may be seen on an electroencephalogram (EEG). It occurs during stage 2 NREM sleep. It is the "largest event in healthy human EEG". [1] They are more …

May 1, 2023 · 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 …

Sep 7, 2023 · K complexes are long delta waves that occur one at a time and last for approximately one second. They are the longest and one of the most distinct of all brain …

Oct 1, 1997 · 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.

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.

…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 …

May 1, 2002 · 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 …

The K-complex is a waveform pattern observed in electroencephalography (EEG) signals during sleep. It is characterized by a distinct and sharp negative deflection followed by a slower …

We aimed to integrate new data about K-complex (KC) physiology and relate KC to other low-frequency waves observed in slow wave sleep. KC can be considered a 'prototype' of reactive …

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.
