    Researchers studied movement-related potentials during skilled arm movements. A Bereitschaftspotential preceded movement, followed by a goal-directed movement potential, indicating distinct neural activity phases during voluntary actions.

    Area of Science:

    • Neuroscience
    • Motor Control
    • Electrophysiology

    Background:

    • Understanding the neural mechanisms underlying voluntary movement is crucial.
    • Movement-related potentials (MRPs) provide insights into cortical activity preceding and during motor tasks.

    Purpose of the Study:

    • To investigate the characteristics of scalp-recorded movement-related potentials during self-paced, skilled upper extremity positioning tasks.
    • To differentiate between the Bereitschaftspotential and subsequent potentials during goal-directed movements.

    Main Methods:

    • Electroencephalography (EEG) was used to record scalp potentials in human subjects.
    • Subjects performed two skilled positioning tasks involving upper extremity flexions without external cues.
    • Delayed visual feedback was provided after each trial.

    Main Results:

    • A negative potential shift, the Bereitschaftspotential, preceded electromyographic (EMG) onset.
    • A persisting negativity, the goal-directed movement potential, was observed during movement execution until the target position was reached.
    • This potential comprised a central negativity and a contralateral sensorimotor negativity.
    • Anticipation of visual feedback elicited a different potential topography, predominantly over the right hemisphere.

    Conclusions:

    • The study identified distinct phases of cortical activity during voluntary movement, characterized by the Bereitschaftspotential and the goal-directed movement potential.
    • The findings suggest specific neural processes associated with movement initiation, execution, and response to feedback.
