“…It is specialized in verbal cognition, gestures, fine motor skills, and control of sequence of movements, while the right-hemisphere in right-handers-in nonverbal cognition, postural control and positional aspects of movements [67][68][69][70]. When controlling hand movements, dominant hemisphere is specialized in limb trajectory control, and nondominant-in limb position control [71][72][73][74][75][76][77][78][79][80][81][82][83][84][85][86][87].…”

“…The non-dominant hand is better in the task of comparing proprioceptive goals than the dominant hand: RH in left-handers and LH in right-handers [99]. The study of the accuracy of hand movements when reproducing sequences modified according to the principle of position constancy suggests that the subdominant hemisphere of both righthanders and left-handers remembers and uses information about positions, despite the change in the movements themselves [86].When reproducing sequences modified by the principle of constancy of the amplitude and direction of movement (and changing the position), the dominant hemisphere in both right-handers and left-handers remembers and uses information about the parameters of the movements [87].…”

“…But why is this observed only for RH, but not for LH? Here, apparently, the answer lies in the differences in the organization of movementsballistic in the left hemisphere and positional-in the right one [71][72][73][74][75][76][77][78][79][80][81][82]84,86,87,115]. When imagining movements, feedbacks are not involved, therefore, the factor of complexity of imagery movements connected with the left hemisphere and with the imagination of RH movements in "pure" right-handers (in latent left-handers only a tendency, p < 0.1).…”

“…As to other traits that revealed a correlation with ARH in "pure" right-handersliveliness (F) and dominance (E)-there is no direct information in the literature, however, these personality traits consistently complement the image of the user-extrovert who more successfully controls BCI when imagining RH movements. It is known that when organizing movements, left-handers are characterized by "mirroring", that is, when performing movements, the dominant hemisphere of both left-handers and right-handers regulates work of the dominant hand and controls ballistic movements, and the subdominant hemisphere provides a description of positions (positional coding) using feedbacks when organizing movements: the non-dominant hand copes better with positional tasks-RH in left-handers and LH-in right-handers [71][72][73][79][80][81][82]86,87,99,115]. It seems likely that the higher sensitivity (I), the greater the inflow of afferent kinesthetic information that provides feedbacks, and feedbacks, as mentioned above, are used to a greater extent when organizing movements by the right hemisphere of right-handers and the left hemisphere of left-handed ones.…”

“…Studying RH and LH movement sequences in right-and left-handers demonstrates that during the first reproduction of a memorized sequence of movements, errors are "mirrored". However, when the same sequence is reproduced with the opposite hand (skill transfer), "mirroring" is lost and the errors depend on other aspects, which are nevertheless also associated with laterality [87].…”

Brain-computer interfaces (BCIs), based on motor imagery, are increasingly used in neurorehabilitation. However, some people cannot control BCI, predictors of this are the features of brain activity and personality traits. It is not known whether the success of BCI control is related to interhemispheric asymmetry. The study was conducted on 44 BCI-naive subjects and included one BCI session, EEG-analysis, 16PF Cattell Questionnaire, estimation of latent left-handedness, and of subjective complexity of real and imagery movements. The success of brain states recognition during imagination of left hand (LH) movement compared to the rest is higher in reserved, practical, skeptical, and not very sociable individuals. Extraversion, liveliness, and dominance are significant for the imagination of right hand (RH) movements in “pure” right-handers, and sensitivity in latent left-handers. Subjective complexity of real LH and of imagery RH movements correlates with the success of brain states recognition in the imagination of movement of LH compared to RH and depends on the level of handedness. Thus, the level of handedness is the factor influencing the success of BCI control. The data are supposed to be connected with hemispheric differences in motor control, lateralization of dopamine, and may be important for rehabilitation of patients after a stroke.

Electroencephalographic and Autonomic Correlates of Imaginary and Real Movements of Legs in Right-Handers and Left-Handers

Abstract— Changes in the spectral power (SP) of electroencephalogram (EEG) in the α-band and the heart rate variability (HRV) were studied in subjects with right and left motor dominance profiles during imaginary and real flexion of right and left feet. During the implementation of motor tasks, a pronounced desynchronization of α-rhythm in frontal and central leads and its less significant changes in parietal and occipital zones of both hemispheres were revealed. The peculiarity of right-handers during mental and real leg movements was the variable and asymmetric character of changes in the SP of α-rhythm in the bilateral leads from various cortical areas. In left-handed subjects, when imagining and performing movements, the desynchronization of α-rhythm in different leads had the same severity and there were practically no hemispheric asymmetry in SP. Right-handers had are latively stable vegetative status during the performance of motor tasks, and HRV changes occurred mainly with real leg movements. In left-handers HRV parameters changed more strongly and mainly during mental actions with their feet. Correlations were found between the α-rhythm SP and HRV parameters, depending on the type of movement and the motor dominance profile of subjects. The obtained data reflect the peculiarities of regulation mechanisms of voluntary leg movements and the differences in the vegetative support of motor activity in right-handed and left-handed people.
