“…Furthermore, beta power decreases have been associated with the temporal predictability of stimulus occurrence (Alegre et al, 2003(Alegre et al, , 2006. Beta power and coherence changes have also been suggested to be related to syntactic and semantic processing (Wang et al, 2012;Weiss & Mueller, 2012;Bastiaansen et al, 2010;Weiss et al, 2005).…”

“…Turning to the interpretation of the EEG signals, it is well established that power decreases in the beta band can be observed during preparation for a movement above the sensorimotor areas (Alegre et al, 2006;Rektor, Sochůrková, & Bočková, 2006;Pfurtscheller & Lopes da Silva, 1999;Pfurtscheller & Aranibar, 1977;Jasper & Penfield, 1949).

Abstract■ RTs in conversation, with average gaps of 200 msec and often less, beat standard RTs, despite the complexity of response and the lag in speech production (600 msec or more). This can only be achieved by anticipation of timing and content of turns in conversation, about which little is known. Using EEG and an experimental task with conversational stimuli, we show that estimation of turn durations are based on anticipating the way the turn would be completed. We found a neuronal correlate of turn-end anticipation localized in ACC and inferior parietal lobule, namely a betafrequency desynchronization as early as 1250 msec, before the end of the turn. We suggest that anticipation of the otherʼs utterance leads to accurately timed transitions in everyday conversations. ■

“…In contrast, only a handful of studies have analyzed the modulation of ␤-activity further back in time during the foreperiod (for review, see Kilavik et al, 2013). Using precueing paradigms several studies have reported intermittent ␤-band peaks during the foreperiod between the warning and the imperative cues (Alegre et al, 2004(Alegre et al, , 2006Molnár et al, 2008;van Wijk et al, 2009;Fischer et al, 2010;Zaepffel et al, 2013). First, Alegre et al (2004Alegre et al ( , 2006 reported multiple, largely independent ␤-power peaks in this epoch, of frontal and central sources.…”

“…As adaptive motor-command adjustments might be reflected in the preparation of subsequent movements, we also examined ␤-band activity during the preparation of reaches immediately after perturbed movements. Some studies have suggested a link between ␤-oscillations and motor planning in the foreperiod, between the warning and imperative stimuli (Alegre et al, 2006;Zaepffel et al, 2013; for review, see Kilavik et al, 2013). In the first experiment, participants reached to a visual target in a force field created by a robotic device, and movementexecution errors of different sizes were produced by unpredictable changes in the strength of the applied force (Torrecillos et al, 2014).…”

Distinct Modulations in Sensorimotor Postmovement and Foreperiod β-Band Activities Related to Error Salience Processing and Sensorimotor Adaptation

et al. 2015

In a recent study, Tan et al. (2014a,b) showed that the increase in ␤-power typically observed after a movement above sensorimotor regions (␤-rebound) is attenuated when movement-execution errors are induced by visual perturbations. Moreover, akin to sensorimotor adaptation, the effect depended on the context in which the errors are experienced. Thus the ␤-rebound attenuation might relate to neural processes involved in trial-to-trial adaptive mechanisms. In two EEG experiments with human participants, along with the ␤-rebound, we examine ␤-activity during the preparation of reaches immediately following perturbed movements. In the first experiment, we show that both foreperiod and postmovement ␤-activities are parametrically modulated by the sizes of kinematic errors produced by unpredictable mechanical perturbations (force field) independent of their on-line corrections. In the second experiment, we contrast two types of reach errors: movement-execution errors that trigger trial-to-trial adaptive mechanisms and goal errors that do not elicit sensorimotor adaptation. Movement-execution errors were induced by mechanical or visual perturbations, whereas goal errors were caused by unexpected displacements of the target at movement initiation. Interestingly, foreperiod and postmovement ␤-activities exhibit contrasting patterns, pointing to important functional differences of their underlying neuronal activity. While both types of reach errors attenuate the postmovement ␤-rebound, only the kinematic errors that trigger trial-to-trial motor-command updates influenced ␤-activity during the foreperiod. These findings suggest that the error-related modulation of the ␤-rebound may reflect salience processing, independent of sensorimotor adaptation. In contrast, modulations in the foreperiod ␤-power might relate to the motorcommand adjustments activated after movement-execution errors are experienced.

The cortical oscillatory patterns associated with varying levels of reward during an effortful vigilance task

et al. 2020

We explored how reward and value of effort shapes performance in a sustained vigilance, reaction time (RT) task. It was posited that reward and value would hasten RTs and increase cognitive effort by boosting activation in the sensorimotor cortex and inhibition in the frontal cortex, similar to the horse-race model of motor actions. Participants performed a series of speeded responses while expecting differing monetary rewards (0 pence (p), 1 p, and 10 p) if they responded faster than their median RT. Amplitudes of cortical alpha, beta, and theta oscillations were analysed using the event-related desynchronization method. In experiment 1 (N = 29, with 12 females), reward was consistent within block, while in experiment 2 (N = 17, with 12 females), reward amount was displayed before each trial. Each experiment evaluated the baseline amplitude of cortical oscillations differently. The value of effort was evaluated using a cognitive effort discounting task (COGED). In both experiments, RTs decreased significantly with higher rewards. Reward level sharpened the increased amplitudes of beta oscillations during fast responses in experiment 1. In experiment 2, reward decreased the amplitudes of beta oscillations in the ipsilateral sensorimotor cortex. Individual effort values did not significantly correlate with oscillatory changes in either experiment. Results suggest that reward level and response speed interacted with the task-and baseline-dependent patterns of cortical inhibition in the frontal cortex and with activation in the sensorimotor cortex during the period of motor preparation in a sustained vigilance task. However, neither the shortening of RT with increasing reward nor the value of effort correlated with oscillatory changes. This implies that amplitudes of cortical oscillations may shape upcoming motor responses but do not translate higher-order motivational factors into motor performance.
