“…Although such a decrease in pattern accuracy (i.e. coordination performance) was not surprising, this result suggests that asymmetry between the 2 hands changed with aging, thereby leading to a larger shift in relative phase [38] .…”

The present study examined the effects of aging on the execution of a bimanual coordination task in a classical phase transition paradigm in which coordination patterns (in-phase and anti-phase) and movement frequency were manipulated. Two groups of adults, the so-called young (average age 26 years) and old (average age 71 years) participants, performed both in-phase and anti-phase patterns at different frequencies. As we expected variability of relative phase was larger for older participants than for younger ones for both the in-phase and the anti-phase coordination patterns. Moreover, phase transitions occurred at lower frequencies for older participants and more transitions were observed for older than for younger participants. Although no specific hypotheses were made about the prominent source(s) of age-related changes in coordination dynamics (i.e., an alteration in the coupling function and/or an increase of the magnitude of noise), our results suggest that these changes might result from increases in the (neural) noise to be found in the (bimanual) action system.

“…The latter is of additional importance when performing bimanual acts during which spatial coupling represents an intrinsic constraint [16,31]. This organization evokes bimanual interactions through a coupling mechanism of which the dominant limb exerts a stronger influence on the nondominant limb than vice versa [9,13]. The latter asymmetrical arrangement is supported by an inherent attentional bias towards the dominant hand [36], such that strategies that modify this preference also change the trajectories of the individual motions [15,48].…”

“…However, performance difficulties arise when asymmetrical acts are required such as when moving the hands with dissimilar tempo or spatial requirements. In this case, assimilation or interference occurs [16,27]; an effect that is sensitive to handedness-related asymmetries, enabling the dominant limb to exert a stronger influence on the non-dominant limb than vice versa [9,13]. During motor behaviour, vision and proprioception are critical sources of information that interact for planning, execution and monitoring of performance.…”

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.

“…For instance, the devices used in finger tapping experiments measure only one finger position per cycle (e.g. Aramaki et al, 2006), preventing the quantification of kinematic variables relevant for the detection of asymmetries between limbs, such as the absolute amplitude of oscillations and/or hand dominance Peper and Beek, 1998;Beek et al, 2002;de Poel et al, 2007de Poel et al, , 2009Peper et al, 2008). In other experimental settings, movement kinematics can be obtained only indirectly after extensive pre-processing of signals of different origin (Schaechter et al, 2006;MacIntosh et al, 2007).…”
