“…Likewise, the presence of enhanced beta modulation during motor learning that we report is compatible with other studies on altered cortical activity during motor skill acquisition (Recanzone et al, 1992;Pascual-Leone et al, 1994;Sanes and Donoghue, 2000). Our results also complement reports on enhanced event-related alpha desynchronization during (implicit) motor learning (Zhuang et al, 1997), increased cortico-spinal beta synchronization following visuo-motor skill learning (Perez et al, 2006) and increased interhemispheric synchronization during the early stage of bilateral learning (Andres et al, 1999). Taken together, these findings suggest that the change in beta modulation reflects a reorganization of neural activity in the motor cortex during skill acquisition.…”

Although the relationship between brain activity and motor performance is reasonably well established, the manner in which this relationship changes with motor learning remains incompletely understood. This paper presents a study of cortical modulations of eventrelated beta activity when participants learned to perform a complex bimanual motor task: 151 channel MEG data were acquired from nine healthy adults whilst learning a bimanual 3:5 polyrhythm. Sources of MEG activity were determined by means of synthetic aperture magnetometry that yielded locations and time courses of beta activities. The relationship between changes in performance and corresponding changes in event-related power were assessed using partial least squares. Behavioral data revealed that participants successfully learned to perform the 3:5 polyrhythm and that performance improvement was mainly achieved through the proper timing of the finger producing the slow rhythm. We found event-related modulation of beta power in the contralateral motor cortex that was inversely related to force output. The degree of beta modulation increased during the experimentalthough the force level remained constant -and was positively correlated with motor performance, in particular for the motor cortex contralateral to the slow hand. These electrophysiological findings support the view that activity in motor cortex co-varies closely with behavioral changes over the course of learning.

“…This is consistent with evidence that as a motor sequence is explicitly learned, the contribution of the motor cortex execution of the task is reduced while other brain structures assume more active roles [PascualLeone et al, 1999]. Moreover, Zhuang et al [1997] have reported mu increases (relative to baseline) after overlearning in many of their subjects. Further, we investigated if the prestimulus oscillatory power correlated with subsequent reaction-times on a trial-by-trial basis.…”

Do certain brain states predispose humans to commit errors in monotonous tasks? We used MEG to investigate how oscillatory brain activity indexes the brain state in subjects performing a Go-noGo task. Elevated occipital alpha and sensorimotor mu activity just prior to the presentation of the stimuli predicted an upcoming error. An error resulted in increased frontal theta activity and decreased posterior alpha activity. This theta increase and alpha decrease correlated on a trial-by-trial basis reflecting post-error functional connectivity between the frontal and occipital regions. By examining the state of the brain before a stimulus, we were able to show that it is possible to predict lapses of attention before they actually occur. This supports the case that the state of the brain is important for how incoming stimuli are processed and for how subjects respond.

“…Similarly, stronger reduction of the alpha power was associated with smaller errors in golf performance (Babiloni and del Percio et al, 2008), semantic task , higher memory performance (Klimesch and Doppelmayr et al, 1997), motor skill learning (Zhuang and Toro et al, 1997). Experimental data also support the idea of ERDs correlate activated cortical networks related to processing of higher order social information (Oberman and , perception of information (Perry and Troje et al, 2010), information processing and selective attention (Klimesch, 1999), motor preparation and execution (Pfurtscheller and Lopes da Silva, 1999).…”
