“…Alternatively, PMBR could reflect the active inhibition of the motor cortex to terminate a movement 58 . The observation of a single PMBR following a sequence of discrete movements 13,59 and its association to movement parameters such as accuracy, variability, and rate of force development 60,61 have been taken as an argument for its involvement in the active inhibition of the motor cortex following movement termination.…”

Although the engagement of sensorimotor cortices in movement is well documented, the func-tional relevance of brain activity patterns remains ambiguous. Especially, the cortical engage-ment specific to the pre-, within-, and post-movement periods is poorly understood. The pre-sent study addressed this issue by examining sensorimotor EEG activity during the perfor-mance as well as STOP-signal cued suppression of movements pertaining to two distinct clas-ses, namely, discrete vs. ongoing rhythmic movements. Our findings indicate that the lateral-ized readiness potential (LRP), which is classically used as a marker of pre-movement pro-cessing, indexes multiple pre- and in- movement-related brain dynamics in a movement-class dependent fashion. In- and post-movement event-related (de)synchronization (ERD/ERS) ob-served in the Mu (8-13 Hz) and Beta (15-30 Hz) frequency ranges were associated with esti-mated brain sources in both motor and somatosensory cortical areas. Notwithstanding, Beta ERS occurred earlier following cancelled than actually performed movements. In contrast, Mu power did not vary. Whereas Beta power may reflect the evaluation of the sensory predicted outcome, Mu power might engage in linking perception to action. Additionally, the rhythmic movement forced stop (only) showed a post-movement Mu/Beta rebound, which might re-flect an active "clearing-out" of the motor plan and its feedback-based online control. Overall, the present study supports the notion that sensorimotor EEG modulations are key markers to investigate control or executive processes, here initiation and inhibition, which are exerted when performing distinct movement classes.
