“…Under the experimental conditions tested here, it suggests that sensorimotor beta-band desynchronization is more closely linked with movement initiation than with the encoding of the spatial aspects of movements. This view is consistent with evidence that EEG beta-band activity during the preparatory period yields poor directional decoding accuracy of hand movement direction ( Waldert et al, 2008) and is not influenced by upcoming visual feedback direction (Dufour, Thénault, & Bernier, 2018). However, these results are inconsistent with those of Tzagarakis et al (2010), who used magnetoencephalography (MEG) and found that beta-band desynchronization during planning negatively scaled with the directional uncertainty of an upcoming movement.…”

It is well documented that providing advanced information regarding the spatial location of a target stimulus (i.e., spatial anticipation) or its timing of occurrence (i.e., temporal anticipation) influences reach preparation, reducing RTs. Yet, it remains unknown whether the RT gains attributable to temporal and spatial anticipation are subtended by similar preparatory dynamics. Here, this issue is addressed in humans by investigating EEG beta-band activity during reach preparation. Participants performed a reach RT task in which they initiated a movement as fast as possible toward visual targets following their appearance. Temporal anticipation was manipulated by having the target appear after a constant or variable delay period, whereas spatial anticipation was manipulated by precueing participants about the upcoming target location in advance or not. Results revealed that temporal and spatial anticipation both reduced reach RTs, with no interaction. Interestingly, temporal and spatial anticipation were associated with fundamentally different patterns of beta-band modulations. Temporal anticipation was associated with beta-band desynchronization over contralateral sensorimotor regions specifically around the expected moment of target onset, the magnitude of which was correlated with RT modulations across participants. In contrast, spatial anticipation did not influence sensorimotor activity but rather led to increased beta-band power over bilateral parieto-occipital regions during the entire delay period. These results argue for distinct states of preparation incurred by temporal and spatial anticipation. In particular, sensorimotor beta-band desynchronization may reflect the timely disinhibition of movement-related neuronal ensembles at the expected time of movement initiation, without reflecting its spatial parameters per se.

“…Several lines of reasoning support this possibility. First, the planning and execution of reaching movements with and without vision is subtended by partially distinct patterns of neural activity, which may lead to the emergence of context‐specific motor memories . As such, this contention is indirectly supported by the large differences in movement kinematics that were observed here between vision and no‐vision trials.…”

The combination of behavioral experiences that enhance long-term retention remains largely unknown. Informed by neurophysiological lines of work, this study tested the hypothesis that performance-contingent monetary rewards potentiate repetition-dependent forms of learning, as induced by extensive practice at asymptote, to enhance long-term retention of motor memories. To this end, six groups of 14 participants (n = 84) acquired novel motor behaviors by adapting to a gradual visuomotor rotation while these factors were manipulated. Retention was assessed 24 h later. While all groups similarly acquired the novel motor behaviors, results from the retention session revealed an interaction indicating that rewards enhanced long-term retention, but only when practice was extended to asymptote. Specifically, the interaction indicated that this effect selectively occurred when rewards were intermittently available (i.e., 50%), but not when they were absent (i.e., 0%) or continuously available (i.e., 100%) during acquisition. This suggests that the influence of rewards on extensive practice and long-term retention is nonlinear, as continuous rewards did not further enhance retention as compared with intermittent rewards. One possibility is that rewards' intermittent availability allows to maintain their subjective value during acquisition, which may be key to potentiate long-term retention.

“…Hughes and Waszak (2011) reported the post-response LRP in a time-estimation task to be enhanced on trials in which a task-irrelevant visual outcome was anticipated (onset of a checkerboard 400 ms after keypress). Using time-frequency analysis, Dufour et al (2018) observed a difference in theta power at sites overlying sensorimotor cortex during the 500-ms interval just before reaching movements in conditions with versus without visual guidance cues. These findings are consistent with the idea that anticipatory activity in primary sensorimotor cortex includes estimating the visual consequences of a movement (i.e., a forward model; Miall & Wolpert, 1996).…”

Learning to deal with delayed outcomes: EEG oscillatory and slow potentials during the prefeedback interval

It is well established that the stimulus-preceding negativity (SPN) decreases in amplitude as a task is mastered, a phenomenon generally attributed to the reduction in anticipatory attention as feedback becomes less needed. Typically, the experiments supporting this assumption have used relatively short delays (<3 s). However, we found in a previous study that this decline in amplitude, although present during the 2.5-s prefeedback delay of a patterned key-pressing task, was absent with an 8-s delay. We reexamined this finding using a 6-s delay and found that the SPN diminished at frontal sites as participants learned a sequence of four keypress durations, but that this modulation was limited to the early half of the delay (maximum at 2 s).Decline of lateralized sensorimotor theta activity across trials was also limited to early portions of the delay. These findings suggest that processes other than anticipatory attention to feedback may be more relevant for explaining SPN diminution. Such processes could include adjustment and maintenance of action-outcome expectancies (e.g., forward models) during the prefeedback interval.
