K-Complexes are sudden bursts of brain activity that occur during sleep, often in response to external stimuli. They help your brain transition between sleep stages and can indicate that you're getting quality rest.
If you're shopping for a mattress and learn about K-Complexes, you might consider how a mattress that minimizes disturbances can help you achieve deeper sleep.
K-complexes are brain wave patterns that indicate the brain's response to external stimuli during sleep, often serving as a protective mechanism to maintain sleep.
K-complexes are sharp, high-amplitude waves that occur in response to stimuli, while sleep spindles are bursts of oscillatory brain activity that play a role in memory consolidation and are typically associated with deeper sleep.
K-complexes primarily occur during NREM sleep, particularly in stage 2, and are often associated with transitions between sleep stages.
K-complexes were first described by sleep researcher Nathaniel Kleitman in the 1930s, leading to their naming after him.
