    This study introduces a novel method for visualizing electroencephalography (EEG) spectral analysis. The technique maps brainwave rhythms across the cerebral hemispheres, aiding in the understanding of neurological activity.

    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Signal Processing

    Context:

    • Electroencephalography (EEG) is crucial for studying brain activity.
    • Topographical mapping of EEG data enhances spatial understanding.
    • Current methods may lack detailed spectral visualization.

    Purpose:

    • To develop a method for topographical display of spectral electroencephalography (EEG) analysis.
    • To visualize EEG data from 16 channels, including hemispheric and midline electrodes.
    • To represent spectral intensities within delta, theta, alpha, and beta bands.

    Summary:

    • A novel method multiplexes and samples 16-channel EEG data at 3.2 kHz.
    • Spectral parameters, including band intensities, are computed from averaged power spectra.
