Rapid, conjugate eye movements (EOG) and profound muscle atonia (paralysis seen on EMG), punctuated by transient muscle twitches. 5. Clinical Relevance: Abnormal EEG Patterns in Sleep
– Focus slide defining Sleep Spindles, K-Complexes, and Vertex Waves.
Low-amplitude, mixed-frequency background activity resembling an active wake or N1 state. Distinctive "Sawtooth Waves" (triangular, jagged 2–6 Hz waves) often precede bursts of eye movements. EOG: Sharp, irregular, asymmetric Rapid Eye Movements . eeg and sleep physiology ppt
Conclude by linking healthy sleep architecture to real-world pathophysiological abnormalities, demonstrating the real-world utility of EEG sleep staging.
– EEG criteria, scoring rules, and physiological characteristics. Rapid, conjugate eye movements (EOG) and profound muscle
To explore how the brain cycles through distinct electrical patterns to restore the body and mind. ⚡ Slide 2: What is an EEG?
: Good slides often use "montages" that combine EEG with EOG (eye movement) and EMG (muscle tone) data, which is necessary to identify REM sleep accurately. Conclude by linking healthy sleep architecture to real-world
High-frequency, low-amplitude, with prominent Alpha waves when eyes are closed. B. NREM Sleep (Non-Rapid Eye Movement)
Marked by the definitive appearance of sleep spindles and/or K-complexes . The background remains LAMF theta activity.
