    Area of Science:

    • Neuroscience
    • Signal Processing
    • Biomedical Engineering

    Background:

    • Electroencephalography (EEG) is crucial for understanding brain activity.
    • Current methods for EEG analysis can be complex and time-consuming.
    • A need exists for efficient and intuitive EEG data visualization.

    Purpose of the Study:

    • To present a novel method for representing EEG parameters.
    • To facilitate the immediate estimation of EEG activity changes.
    • To offer insights into individual wave properties and epoch characteristics.

    Main Methods:

    • Utilizes a bidimensional plot of two electroencephalogram (EEG) signals.
    • Employs a block diagram for recording phase-sensitive parameter variations.
    • Incorporates oscilloscopes or X-Y graphic recorders for display.
    • Provides charts for setting parameters in analog and digital phase-shifting arrangements.

    Main Results:

    • The method allows for a clear representation of EEG parameters.
    • Phase-sensitive variations in EEG signals can be effectively visualized.
    • The technique captures both individual wave properties and epoch characteristics.
    • Enables immediate estimation of changes in EEG activity.

    Conclusions:

    • The described bidimensional plotting method offers an effective way to represent EEG data.
    • This approach enhances the immediate assessment of EEG activity.
    • The technique is valuable for analyzing both specific wave features and broader EEG patterns.
