“…Our studies' results may provide new explanations of the different effects of the research on the relationship between handedness and MI-BCIs control 13,14 . According to our hypotheses, right-and left-handed differ in their ability to imagine a movement from a kinesthetic and visual-motor perspective.…”

“…The signal was divided into 5500 ms long segments (baseline from −2000 to 0 ms, event period from 0 to 3500 ms) and subjected to time-frequency decomposition with Event-Related Spectral Perturbation 34 using sinusoidal wavelet transformations (3-cycles; 0.5 s) to calculate the signal strength (dB) for the entire window. For statistical analyses, signal strength for alpha (8)(9)(10)(11)(12)(13) and beta (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) frequency bands in the same time window (500 -3000 ms) was averaged across individual ICs within the parietal and occipital clusters. The statistical analysis was carried out separately for three ICs clusters: parietal right, parietal left ( Fig.…”

“…The experiments described above have shown that handedness can affect the mental representation of movement, re ected both at the behavioral level 12 and in differences in brain activity patterns 13,14 . However, discrepancies in the direction of these differences may indicate additional factors in uencing the results.…”

“…It was noted that left-handed individuals could rely more on the hand position's visual assessment than on sensorimotor sensations such as the right-handed. In their case study, Carino-Escobar et al 13 were looking to verify how these preferences affect MI-BCI performance by analyzing physiological, anatomical, and psychological differences between monozygotic twins discordant handedness. Contrary to the authors' expectations, the left-handed participant achieved better BCI control, whether the feedback was provided visually or kinesthetically.…”

Recent studies show that during a simple movement imagery task, the power of sensorimotor rhythms differs according to handedness. However, the effects of motor imagery perspectives on these differences have not been investigated yet. Our study aimed to check how handedness impacts the activity of alpha (8 - 13 Hz) and beta (15 - 30 Hz) oscillations during creating a kinesthetic (KMI) or visual-motor (VMI) representation of movement. Forty subjects (20 right-handed and 20 left-handed) who participated in the experiment were tasked with imagining sequential finger movement from a visual or kinesthetic perspective. Both the electroencephalographic (EEG) activity and behavioral correctness of the imagery task performance were measured. After the registration, we used independent component analysis (ICA) on EEG data to localize visual- and motor-related EEG sources of activity shared by both motor imagery conditions. Significant differences were obtained in the visual cortex (the occipital ICs cluster) and the right motor-related area (right parietal ICs cluster). In comparison to right-handers who, regardless of the task, demonstrated the same pattern in the visual area, left-handers obtained higher power in the alpha waves in the VMI task and better performance in this condition. On the other hand, only the right-handed showed different patterns in the alpha waves in the right motor cortex during the KMI condition.The results indicate that left-handers imagine movement differently than right-handers, focusing on visual experience. This provides new empirical evidence on the influence of movement preferences on imagery processes and has possible future implications for research in the area of neurorehabilitation and motor imagery-based brain-computer interfaces (MI-BCIs).
