    Area of Science:

    • Neuroscience
    • Surgical Education
    • Motor Learning

    Background:

    • Laparoscopic surgery demands specialized motor skills acquired through extensive training.
    • Understanding the neurophysiological basis of motor learning is crucial for optimizing surgical education.

    Purpose of the Study:

    • To investigate neurophysiological changes during motor learning in a laparoscopic task.
    • To correlate electroencephalographic (EEG) signal changes with skill acquisition and performance improvements.

    Main Methods:

    • Eight subjects performed a bimanual coordination task in a laparoscopic simulator.
    • Electroencephalographic (EEG) signals were recorded across four training sessions.
    • Spectral power in theta, alpha, and beta bands, task performance, and mental workload were analyzed.

    Main Results:

    • Significant improvements in task performance were observed with training.
    • Changes in spectral power measurements (theta, alpha, beta bands) indicated neurophysiological adaptation.
    • Task score and mental workload perception correlated with training progression.

    Conclusions:

    • Motor learning in laparoscopy involves distinct neurophysiological changes detectable via EEG.
    • Electrophysiological recordings offer a potential objective method for assessing surgical resident training progress.
