Study Notes

Sleep Waves and Stages

Beta Waves: Characteristic of alert waking activity, indicative of focused mental activity.
Sleep Spindles: Occur during NREM sleep, specifically during N2 sleep stage. They are bursts of brain activity linked to memory consolidation and sleep stability.

Polysomnography Measures

Actigraphy: This measure assesses body movement to help stage REM sleep, providing insights into sleep quality and patterns.
Electrooculography (EOG): Measures eye movements during polysomnography, crucial in identifying REM sleep stages.

Stages of Sleep

N3 Sleep (Deep Sleep): Characterized by delta waves, which are high amplitude and low frequency. This stage is essential for restorative processes in the body and brain.
