WebMay 11, 2024 · An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp. Brain cells communicate via electrical impulses and are active all the time, even during asleep. This activity shows up as wavy lines on an EEG recording. WebConclusions: EEG alpha spindle parameters increase both fatigue detection sensitivity and specificity as compared to EEG alpha-band power. Significance: It is demonstrated that alpha spindles are superior to EEG band power measures for assessing driver fatigue under real traffic conditions.
