“…How-ever, a tight interhemispheric coupling can also be detrimental when the arms have to be moved simultaneously along different trajectories. In this case, unwanted information overflow gives rise to spatial interference, as reflected by mutual assimilation effects with respect to movement direction [Franz, 1997;Franz et al, 2000;Franz and Ramachandran, 1998;Swinnen et al, 2001Swinnen et al, , 2002Wenderoth et al, 2003] or movement amplitude [Franz, 1997;Sherwood, 1994;Sherwood and Nishimura, 1999;Spijkers and Heuer, 1995;Swinnen et al, 2001;Walter et al, 2001].…”

Bimanual interference emerges when spatial features, such as movement direction or amplitude, differ between limbs, as indicated by a mutual bias of limb trajectories. Although first insights into the neural basis of directional interference have been revealed recently, little is known about the neural network associated with amplitude interference. We investigated whether amplitude versus directional interference activates differential networks. Functional magnetic resonance imaging (fMRI) was applied while subjects performed cyclical, bimanual joystick movements with either the same vs. different amplitudes, directions, or both. The kinematic analysis confirmed that subjects experienced amplitude interference when they moved with different as compared to the same amplitude, and directional interference when they moved along different as compared to the same direction. On the brain level, amplitude and directional interference both resulted in activation of a bilateral superior parietal-premotor network, which is known to contribute to sensorimotor transformations during goal-directed movements. Interestingly, amplitude but not directional interference exclusively activated a bilateral network containing the dorsolateral prefrontal cortex, anterior cingulate, and supramarginal gyrus, which was shown previously to contribute to executive functions. Even though the encoding of amplitude and directional information converged and activated the same neural substrate, our data thus show that additional and partly independent mechanisms are involved in bimanual amplitude as compared to that in directional control.

“…When movements with different amplitudes have to be produced together by both upper limbs, assimilation effects emerge (Spijkers & Heuer, 1995;Sherwood, 1994;Marteniuk, MacKenzie, & Baba, 1984). Directional interactions have been studied only occasionally (Swinnen, Jardin, Meulenbroek, Dounskaia, & Hofkens-Van Den Brandt, 1997;Swinnen et al, 1998;Franz, Zelaznik, & McCabe, 1991), although it is clear from animal studies using single-cell recording techniques that movement direction is a primary parameter directly or indirectly encoded in various brain areas (for reviews, see Georgopoulos, 1991Georgopoulos, , 1995.…”

Constraints on interlimb coordination have been studied intensively in past years with a primary focus on temporal features. The present study addressed spatial constraints or the degree of directional interference as a function of different line combinations between the upper limbs as well as the modulation of this interference as a result of different board orientations within the performer's workspace. This paradigm was used to address a prominent theme in motor neuroscience, namely whether (bimanual) movements are encoded within an allocentric reference frame (pattern of interference invariant with respect to extrinsic space) or within an egocentric reference frame (pattern of interference invariant relative to the center of the performer's action space, i.e., intrinsic). The observed patterns of interference revealed that movements are primarily encoded within a radial egocentric reference frame in which the performer is the center of action space. The present psychophysical findings converge with primate single-cell recording studies in which the direction has been identified as a primary movement parameter that is encoded in various brain regions, thereby constituting a principal determinant of bilateral interference.

“…For example, when rubbing our stomach and patting our head simultaneously, coupling between the hands can be detrimental. In contrast to temporal coupling, interactions between spatial properties of bimanual movements are strongly influenced by the time given to the participant to prepare and plan the movement (Heuer et al 2001;Spijkers and Heuer 1995;Spijkers et al 1997Spijkers et al , 2000. Furthermore, spatial interactions depend on the way the bimanual movements are cued and conceptualized (Diedrichsen et al 2001Franz et al 2001;Hazeltine et al 2003;Mechsner et al 2001).…”

The role of the corpus callosum in the coupling of bimanual isometric force pulses. J Neurophysiol 90: 2409 -2418, 2003; 10.1152/jn.00250.2003. Two split-brain patients, a patient with callosal agenesis, and 6 age-matched control participants were tested on a bimanual force production task. The participants produced isometric responses with their index fingers, attempting to match the target force specified by a visual stimulus. On unimanual trials, the stimuli were presented in either the left or right visual field and the response was made with the ipsilateral hand. On bimanual trials, two stimuli were presented, one on each side, and the target forces could be either identical or different. Bimanual responses of the control subjects showed strong evidence of coupling. Forces produced by one hand were influenced by the forces produced by the other hand with positive correlations observed for all target force combinations. These assimilation effects and correlations were greatly attenuated in the acallosal group, with similar results observed for the split-brain patients and participant with callosal agenesis. Furthermore, the processes involved in selecting and planning the two responses occurred independently in the acallosal group; in contrast to the controls, the three acallosal participants exhibited no differences in reaction times or accuracy between bimanual trials in which the two target forces were the same or different. We also found a striking temporal desynchronization of the responses in the split-brain patients, indicating that in this context, temporal coupling is impaired after callosotomy. These results are congruent with the hypothesis that interference related to response selection and planning of bimanual force pulses arises from callosal interactions.
