K-Complexes

Meaning

K-Complexes are distinct, high-amplitude, slow-wave electroencephalogram (EEG) patterns that spontaneously occur during Stage 2 non-rapid eye movement (NREM) sleep. These transient neural events are believed to serve a dual function: protecting the brain from being aroused by external stimuli and initiating a process of cortical synchronization and sleep-dependent memory consolidation. They are a physiological marker of stable, non-fragmented sleep architecture, which is vital for endocrine restoration.
