“…Beta activation during execution and observation of goal-directed finger movements revealed the characteristic bi-phasic modulation (Jurkiewicz et al, 2006;Pfurtscheller et al, 1994;Salmelin and Hari, 1994) consistent with earlier studies that have shown similarity between observation and execution of actions in the beta band (e.g. Babiloni et al, 2002;Caetano et al, 2007;Jarvelainen et al, 2004).…”

Motor-cortical beta oscillations are modulated by correctness of observed action

Recent research has demonstrated that cortical motor areas are engaged when observing motor actions of others. However, little is known about the possible contribution of the motor system for evaluating the correctness of others' actions. To address this question we designed an MEG experiment in which subjects were executing and observing motor actions with and without errors. In the execution task subjects were asked to make speeded button presses according to instruction cues. During the observation task, they viewed pictures of an actor's hand making button presses which were correct or incorrect according to the cues. Time-frequency representations of the MEG data demonstrated a depression in oscillatory activity in the beta band activity (15-35 Hz) during execution followed by a beta rebound that was stronger for incorrect compared to correct executions. During the observation task, a similar time-course of the beta activity was identified and importantly the modulations were stronger for the observation of incorrect than correct actions. Sources accounting for the difference in beta activity between correct and incorrect actions were localized using a beamforming technique. Both for the execution and observation conditions sources were identified to the dorsal motor areas comprising both primary and pre-motor cortex. Our findings demonstrate that not only is cortical motor activity modulated by action observation, but the modulation increases when the observed action is erroneous. This suggests that the motor system is engaged in evaluating the correctness of the actions of others.

“…It is widely accepted that beta desynchronization indicates an "active change" in the status of sensorimotor processing (Pfurtscheller and Lopes da Silva, 1999), whereas the beta increase is associated with "maintaining an existing steady state in motor control" (Gilbertson et al, 2005;Pogosyan et al, 2009), "immobilization" (Salmelin et al, 1995), or "reset of an existing cortical network" (Pfurtscheller et al, 2005), reflecting a variety of task and attentional demands. For sensorimotor tasks, slightly different cortical areas seem to be involved in beta suppression and rebound (Salmelin and Hari, 1994;Salmelin et al, 1995;Jurkiewicz et al, 2006;Caetano et al, 2007;Bardouille et al, 2010). Our previous and current findings extend these studies by demonstrating that the difference between suppression and rebound is also manifested in their temporal dynamics.…”

“…The SAM approach uses a linearly constrained minimum variance beamformer algorithm (Van Veen et al, 1997;Robinson and Vrba, 1999), normalizes source power across the whole cortical volume (Robinson, 2004), and is capable of revealing deep brain sources (Vrba and Robinson, 2001;Vrba, 2002). SAM source analysis has been successfully applied for identifying activities in auditory ) and sensorimotor cortices (Jurkiewicz et al, 2006), and deep sources such as hippocampus (Riggs et al, 2009) and fusiform gyrus and amygdala (Cornwell et al, 2008). In examining beta oscillation here, the beamformer was constructed specifically based on the covariances within the magnetic field data, for all epochs of 15-25 Hz bandpass filtered data from Ϫ200 to 1000 ms relative to stimulus onset.…”

Moving in synchrony with an auditory rhythm requires predictive action based on neurodynamic representation of temporal information. Although it is known that a regular auditory rhythm can facilitate rhythmic movement, the neural mechanisms underlying this phenomenon remain poorly understood. In this experiment using human magnetoencephalography, 12 young healthy adults listened passively to an isochronous auditory rhythm without producing rhythmic movement. We hypothesized that the dynamics of neuromagnetic beta-band oscillations (ϳ20 Hz)-which are known to reflect changes in an active status of sensorimotor functions-would show modulations in both power and phase-coherence related to the rate of the auditory rhythm across both auditory and motor systems. Despite the absence of an intention to move, modulation of beta amplitude as well as changes in cortico-cortical coherence followed the tempo of sound stimulation in auditory cortices and motor-related areas including the sensorimotor cortex, inferior-frontal gyrus, supplementary motor area, and the cerebellum. The time course of beta decrease after stimulus onset was consistent regardless of the rate or regularity of the stimulus, but the time course of the following beta rebound depended on the stimulus rate only in the regular stimulus conditions such that the beta amplitude reached its maximum just before the occurrence of the next sound. Our results suggest that the time course of beta modulation provides a mechanism for maintaining predictive timing, that beta oscillations reflect functional coordination between auditory and motor systems, and that coherence in beta oscillations dynamically configure the sensorimotor networks for auditory-motor coupling.

“…The beta band activity is associated with the maintenance of the current sensorimotor or cognitive state (Engel and Fries, 2010). Decreased beta power and beta synchronization are usually related with the changes of cognitive conditions (Pfurtscheller et al, 2005;Jurkiewicz et al, 2006). Also, beta modulation is expressed more strongly if the maintenance of the status quo is intended or predicted than after novel or erroneous events (Engel, Fries, and Singer, 2001;Engel and Fries, 2010).…”

Discriminant brain connectivity patterns of performance monitoring at average and single-trial levels

Electrophysiological and neuroimaging evidence suggest the existence of common mechanisms for monitoring erroneous events, independent of the source of errors. Previous works have described modulations of theta activity in the medial frontal cortex elicited by either self-generated errors or erroneous feedback. In turn, similar patterns have recently been reported to appear after the observation of external errors. We report cross-regional interactions after observation of errors at both average and single-trial levels. We recorded scalp electroencephalography (EEG) signals from 15 subjects while monitoring the movement of a cursor on a computer screen. Connectivity patterns, estimated using multivariate auto-regressive models, show increased error-related modulations of the information transfer in the theta and alpha bands between frontocentral and frontolateral areas. Conversely, a decrease of connectivity in the beta band is also observed. These network patterns are similar to those elicited by self-generated errors. However, since no motor response is required, they appear to be related to intrinsic mechanisms of error processing, instead of being linked to co-activation of motor areas. Noticeably, we demonstrate that cross-regional interaction patterns can be estimated on a trial-by-trial basis. These trial-specific patterns, consistent with the multi-trial analysis, convey discriminant information on whether a trial was elicited by observation of an erroneous action. Overall, our study supports the role of frequency-specific modulations in the medial frontal cortex in coordinating cross-regional activity during cognitive monitoring at a single-trial basis.
