    is accompanied by adaptive changes in neural processing, yet the extent to which
    feedback‐based practice alters the complexity of cortical activity during movement
    execution remains unclear. The present study examined learning‐associated changes
    in brain complexity during the execution of a sequential arm movement following
    augmented‐feedback‐based practice. Thirty‐eight healthy young adults practiced
    a sequential arm movement with augmented feedback across five sessions. Cortical
    activity was recorded with electroencephalography during the first and last practice
    sessions. Multiscale entropy was used to quantify brain complexity across 50 time
    scales. Behavioral measures indicated improved movement accuracy and reduced dual‐task
    costs across practice. At the cortical level, a significant global decrease in
    entropy was observed from the first to the last practice session. Further analyses
    revealed that the differences were confined to coarse temporal window and midline
    frontal electrodes Fz and FCz. In addition, changes in coarse‐scale entropy at
    FCz were negatively correlated with reductions in absolute error. Together, the
    present findings suggest that augmented‐feedback‐based practice is accompanied
    by a refinement of cortical complexity during movement execution, particularly
    in large‐scale frontal dynamics. Multiscale entropy may therefore provide a sensitive
    framework for capturing learning‐related neural adaptations that complement conventional
    electroencephalographic measures and advance the understanding of motor learning
    at the systems level.</jats:p>"
