Abstract
Comprehension of natural intelligent systems’ capability to exhibit bimanual coordination facilitates the process of building systems with better coordination dynamics. Dark side of the bimanual coordination, ‘Bimanual interference’, is that execution of continuous bimanual movements is heavily constrained by spatiotemporal coupling. Ability of callosotomy patients to draw circle and square patterns with two different hands simultaneously with perfect uncoupling after surgical removal of Carpus callosum, makes the point clear that Carpus callosum plays key role in bimanual interference. This paper introduces a new viewpoint of this phenomenon. While the right-handed subjects were drawing asymmetric clockwise and anticlockwise circles and symmetric circle-square patterns, neural activity of Primary motor cortex, which controls movement execution, is recorded. Here major emphasis is placed on how different frequency band powers of EEG signals from primary motor cortex are altered with respect to different continuous bimanual movements. Results in this study demonstrate the essence of understanding feedback loop connections between Corpus callosum and primary motor cortex.
