“…Therefore, it is plausible that the drop in the power of beta oscillations reflect the release of inhibition, i.e., dis-inhibition, of cortical activity. This dis-inhibition might be potentially useful to cope with the increase in cognitive load during motor adaptation (Schmitz, 2022).…”

Motor adaptation reflects the ability of the sensorimotor system in the brain to flexibly deal with changes in the environment to generate effective motor behaviour. How and whether sleep contributes to the consolidation of motor adaptation remains elusive. In this study, a new motor task was employed which utilizes a highly automatized motor skill to explore the effect of sleep on motor adaptation. We hypothesized that sleep-mediated beta band (13-30Hz) desynchronization would enhance motor adaptation performance. Healthy human experts in typing on the regular computer keyboard, were trained to type on a vertically mirrored keyboard while we recorded electroencephalography (EEG). Their typing performance was assessed after either a full night of sleep with polysomnography, or a similar period of daytime wakefulness. We show that motor adaptation performance improved after overnight sleep but not after daytime wakefulness. Beta oscillatory power as well as the spectral slope of the EEG (1-45Hz) were reduced during mirrored typing compared to regular typing. Notably, sleep caused an even further decrease in the power of beta oscillations. Additionally, overnight changes in the EEG spectral slope during mirrored typing was associated with the overnight changes in adaptive performance. Finally, an increase in fast sleep spindle density (13-15Hz) during the night following motor adaptation training, predicted successful motor adaptation. These findings suggest that sleep plays a crucial role in modulating neural activity and its impact on motor functions. Therefore, our results may be useful for directing and monitoring the effectiveness of rehabilitation interventions.

“…The data also replicate two classic effects in the sensorimotor adaptation literature. First, repeated exposure to the same, large visuomotor rotation has been shown to enhance the rate of adaptation but attenuate the size of the aftereffect (45)(46)(47)(48)(49)(50). The former is attributed to the recall of a successful re-aiming strategy (49), whereas the mechanism for the latter remains an open question (45).…”

Sensorimotor adaptation is essential for keeping our movements well-calibrated in response to changes in the body and environment. For over a century, we have studied sensorimotor adaptation in highly controlled laboratory settings that typically involve small sample sizes. While this approach has proven useful to characterize different learning processes, laboratory studies are typically very underpowered to generate data suited for exploring the myriad of factors that may modulate motor performance. Here, using a citizen science website (testmybrain.org), we collected over 2000 sessions on a visuomotor rotation task. This unique dataset has allowed us to replicate classic motor findings, reconcile controversial findings in the learning and memory literature, and discover novel constraints underlying dissociable implicit and explicit learning processes supporting sensorimotor adaptation. Taken together, this study suggests that large-scale motor learning studies hold enormous potential to advance sensorimotor neuroscience.

“…Hence, while the visual feedback given to the user is altered, the activity to execute might consist of reaching a target through a cursor [5,6,15,19,22,38,40,42,51], or in keeping balance [7][8][9]27,47,48]. Moreover, the motor actions performed by the subject can be guided in different ways, such as: by recording the position of a device mediating the interaction, e.g., a joystick [5,6,34,36], a stylus [2,4,10,12,21,23,24,28,30,35,52], or a robotic manipulator [42,53]; by tracking the motion performed by the human body [7][8][9][25][26][27]47,48]; or even by measuring the force exerted on a handle or acquiring the myoelectric muscle activations [46,54,55]. The VMA-directed discrepancy between the expected and the visually perceived outcome can be introduced by altering the input action in the form of a translation [10,47,…”

“…Alternatively, other studies have displayed the trajectory followed by a cursor directly on a screen; this is utilized to allow subjects to visualize the path they trace in the real world on a tablet through a stylus [21,30]. To introduce the visual perturbation that elicits adaptation, the cursor's direction of movement is rotated [22,23,40,42,52] or even gained [38].…”

The study of visuomotor adaptation (VMA) capabilities has been encompassed in various experimental protocols aimed at investigating human motor control strategies and/or cognitive functions. VMA-oriented frameworks can have clinical applications, primarily in the investigation and assessment of neuromotor impairments caused by conditions such as Parkinson’s disease or post-stroke, which affect the lives of tens of thousands of people worldwide. Therefore, they can enhance the understanding of the specific mechanisms of such neuromotor disorders, thus being a potential biomarker for recovery, with the aim of being integrated with conventional rehabilitative programs. Virtual Reality (VR) can be entailed in a framework targeting VMA since it allows the development of visual perturbations in a more customizable and realistic way. Moreover, as has been demonstrated in previous works, a serious game (SG) can further increase engagement thanks to the use of full-body embodied avatars. Most studies implementing VMA frameworks have focused on upper limb tasks and have utilized a cursor as visual feedback for the user. Hence, there is a paucity in the literature about VMA-oriented frameworks targeting locomotion tasks. In this article, the authors present the design, development, and testing of an SG-based framework that addresses VMA in a locomotion activity by controlling a full-body moving avatar in a custom VR environment. This workflow includes a set of metrics to quantitatively assess the participants’ performance. Thirteen healthy children were recruited to evaluate the framework. Several quantitative comparisons and analyses were run to validate the different types of introduced visuomotor perturbations and to evaluate the ability of the proposed metrics to describe the difficulty caused by such perturbations. During the experimental sessions, it emerged that the system is safe, easy to use, and practical in a clinical setting. Despite the limited sample size, which represents the main limitation of the study and can be compensated for with future recruitment, the authors claim the potential of this framework as a useful instrument for quantitatively assessing either motor or cognitive impairments. The proposed feature-based approach gives several objective parameters as additional biomarkers that can integrate the conventional clinical scores. Future studies might investigate the relation between the proposed biomarkers and the clinical scores for specific disorders such as Parkinson’s disease and cerebral palsy.
