| Parameter | Wake | NREM (N2/N3) | REM | |-------------------|------|--------------------|-------------------| | Heart rate | Normal | Slows, regular | Variable, rapid | | Respiration | Regular | Regular, shallow | Irregular | | BP | Normal | Decreases | Fluctuates | | Temperature | Stable | Declines (central) | No regulation | | Muscle tone | Normal | Reduced | Atonia |

  • Frequency bands:
  • Amplitude and morphology:
  • Filtering, sampling, and artifact considerations:
  • REM (Rapid Eye Movement) – 25% of night

    • Electroencephalography (EEG) is the primary noninvasive tool for measuring brain electrical activity and is central to characterizing sleep. Sleep is an active, regulated physiological state composed of multiple stages with distinct EEG signatures that reflect underlying neural network dynamics. Understanding EEG patterns across wakefulness and sleep informs basic neuroscience, clinical sleep medicine, and cognitive research. eeg and sleep physiology ppt
