    This study introduces a computer technique for analyzing brain evoked potentials. The method systematically identifies and averages peak latencies for more accurate brain signal characterization.

    Area of Science:

    • Neuroscience
    • Computational Neuroscience
    • Signal Processing

    Background:

    • Brain evoked potentials are crucial for understanding neural activity.
    • Systematic characterization of evoked potentials is challenging.
    • Existing methods may lack precision in peak latency analysis.

    Purpose of the Study:

    • To develop a computer technique for systematic characterization of brain evoked potentials.
    • To improve the accuracy of evoked potential analysis through automated peak identification and correction.
    • To establish a reliable method for constructing latency-corrected average evoked potentials.

    Main Methods:

    • Data preprocessing using a causal digital filter.
    • Automated peak search and identification algorithm.
