: Electrodes detect tiny electrical potential changes produced by neurons in the cerebral cortex Clinical Goal : To evaluate sleep architecture
An EEG, or , is a non-invasive test that uses small metal discs called electrodes attached to the scalp to measure electrical impulses produced by brain cells. These impulses appear on a recording as wavy, variable-frequency lines. eeg and sleep physiology ppt
: Cortical responses to internal or external stimuli, representing a mechanism that keeps the cortex suppressed. Slide 7: Non-REM Stage N3 – Slow-Wave Sleep (SWS) Core Concept : Deep, highly synchronized, restorative sleep. eeg and sleep physiology ppt
