    This study developed an automatic method using electroencephalography (EEG) spectral analysis to evaluate vigilance levels. The objective EEG measurement showed high correlation with visual assessment, offering a reliable tool for alertness monitoring.

    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Signal Processing

    Background:

    • Vigilance level assessment is crucial in various fields.
    • Objective and reliable methods for monitoring alertness are needed.
    • Electroencephalography (EEG) offers a potential avenue for vigilance evaluation.

    Purpose of the Study:

    • To develop an automated method for evaluating human vigilance levels.
    • To utilize EEG frequency patterns for objective alertness assessment.
    • To establish the reliability of automated vigilance measurement.

    Main Methods:

    • Collected 41 EEG records for training, representing alert states and sleep stage I.
    • Calculated 22 spectral analysis variables from EEG data.
    • Applied multiple regression analysis to correlate spectral values with vigilance levels.

  • Validated the method on an independent dataset of 265 EEG epochs.

    • Main Results:

    • Achieved a high correlation of 0.89 between automatic and visual vigilance assessment in training data.
    • Obtained a correlation of 0.86 in the independent test dataset.
    • Demonstrated the method's ability to evaluate mean vigilance, variance, rhythmicity, and trend.

    Conclusions:

    • The developed automated EEG method provides a reliable objective measure of vigilance.
    • This technique can be valuable in pharmacological research, psychiatric evaluations, and workplace studies.
    • Objective alertness monitoring using EEG spectral patterns holds significant potential for diverse applications.
