Sleep plays a crucial role in:

Sleep is a fundamental biological process necessary for survival, cognitive function, and physical restoration. Understanding how we sleep requires studying the brain's electrical activity, which is primarily achieved through . eeg and sleep physiology ppt

Sharp negative peaks followed by positive curves. NREM Stage 3 (N3) Known as "Deep Sleep" or Slow Wave Sleep (SWS). Presence of >20% delta waves. Body repair and growth hormone release occur here. REM Sleep (R)

is a non-invasive test that measures and records the electrical activity of the brain using small metal discs (electrodes) attached to the scalp. Physiological Basis Sharp negative peaks followed by positive curves

REM sleep is unique. While the body is paralyzed, the brain is highly active, with EEG readings that closely resemble the "activated" EEG of an awake person. 4. Summary of EEG Frequencies by Stage
