“…The present experiment extends previous work of Lavrysen et al (2008) in right-handed participants by combining the data of right-handers with a newly tested group of lefthanded participants, using exactly the same paradigm. Qualitative analyses of movement kinematics in combination with brain imaging techniques (fMRI) were used to examine the mechanisms underlying manual asymmetries.…”

“…This is typically expressed as a shorter time after peak velocity (i.e., the time to decelerate) when using the right compared to the left hand (Lavrysen et al, 2007;Roy et al, 1994). In our previous fMRI study with right-handers (Lavrysen et al, 2008), the differences found in left and right eye-hand coupling were attributed to functional specialization differences between the left and right hemisphere. Alternatively, they might simply be an expression of the reduced processing effort when using the well-trained preferred hand.…”

“…Hence, left-handers would show the opposite pattern of behavioral and functional asymmetries. To differentiate between these two hypotheses, the present study extended the paradigm of Lavrysen et al (2008) to a group of extremely lateralized left-handers. This group has typically been neglected in the literature compared to the vast amount of publications that addresses right-handers.…”

Hemispheric asymmetries in goal-directed hand movements are independent of hand preference

Asymmetries in the kinematics and neural substrates of voluntary right and left eye-hand coordinated movements have been accredited to differential hemispheric specialization. An alternative explanation for between-hand movement differences could result from hand preference related effects. To test both assumptions, an experiment was conducted with left- and right-handers performing goal-directed movements with either hand paced by a metronome. Spatiotemporal accuracy was comparable between hands, whereas hand peak velocity was reached earlier when moving with the left compared to the right hand. The underlying brain activation patterns showed that both left- and right-handers activated more areas involved in visuomotor attention and saccadic control when using their left compared to the right hand. Altogether, these results confirm a unique perceptuomotor processing specialization of the left brain/right hand system that is independent of hand preference.

“…In line with previous work (Van Halewyck et al , 2015aHalewyck et al , 2015b), a first-order, low-pass Butterworth filter with a cutoff frequency of 20 Hz was applied on the hand position data prior to the calculation of the dependent variables (Lavrysen et al 2007(Lavrysen et al , 2008(Lavrysen et al , 2012Van Halewyck et al 2015a). Filtered data were differentiated twice to obtain instantaneous velocity and acceleration profiles.…”

The present study examines whether nonactive older adults are more dependent on visual information when executing aiming movements and whether age-related declines in proprioception play a mediating role herein. Young (N = 40) and older adults (N = 38) were divided into physically active and non-active subgroups based on self-reported sports participation levels. In experiment 1, participants executed wrist-aiming movements with and without visual feedback. In experiment 2, passive proprioceptive acuity was assessed using wrist motion detection and position matching tests. Results showed similar aiming accuracy across age groups both with and without visual feedback, but older adults exhibited longer movement times, prolonged homing-in phase, and made more corrective submovements. Passive proprioceptive acuity was significantly affected by physical activity level and age, with participants in the active group scoring better than their non-active peers. However, these declines did not predict performance changes on the aiming task. Taken together, our observations suggest that decline in proprioceptive acuity did not predict performance changes on the aiming task and older adults were able to compensate for their decreased motion and position sense when allowed sufficient time. In line with these observations, we proposed that older adults are able to compensate for their decline in proprioception by increasing their reliance on predictive models.

“…Furthermore, the left hand mirror manipulation perturbed drawing behaviour more strongly than the right hand mirror manipulation as a function of task complexity. In this respect, previous work has shown that visuomotor trajectory regulation is inferior for the left than right hand due to processing and attentional differences [29]. Hence, it is likely that in the left hand mirror conditions, subjects experienced more difficulties to cope with visuomotor incongruence in terms of processing effort and attentional demands due to a preferred perception-action coupling through the dominant hand [8].…”

Successful motor behavior depends on optimal information processing and planning. In the present study, the neural response of the motor system to conflict of visuomotor discrepancy (mirror-reversed vision) and complexity (task difficulty and hand laterality) was evaluated during the performance of bimanual actions. EEG coherence, expressing interregional communication, showed that conflict of visuomotor incongruence resulted in activation changes in both hemispheres, whereas conflict of task complexity evoked adjustments primarily in the left hemisphere. Furthermore, interhemispheric coherence was modified due to both forms of conflict. This demonstrates that conflict demands elicit distinct processes across the motor system. The data further illustrate that functional couplings are dynamically modulated during bimanual behaviour, suggesting that interactions between brain regions provide higher-order links for information processing and integration in view of complex motor skills.
