Parallel Specification of Visuomotor Feedback Gains during Bimanual Reaching to Independent Goals
During goal-directed reaching, rapid visuomotor feedback processes enable the human motor system to quickly correct for errors in the trajectory of the hand that arise from motor noise and, in some cases, external perturbations. To date, these visuomotor responses, the gain of which is sensitive to features of the task and environment, have primarily been examined in the context of unimanual re...
متن کاملComparison of Reaching Kinematics During Mirror and Parallel Robot Assisted Movements
The use of robotic devices in rehabilitation allows therapists to administer the desired movement with the preferred level of assistance while expending minimum effort. Robotic devices have been used in recent years to enhance sensori-motor recovery of the impaired arm in persons with stroke. Despite recent recommendations for bimanual practice, robot-assisted bimanual activities are rarely exp...
متن کاملGoal-selection and movement-related conflict during bimanual reaching movements.
Conflict during bimanual movements can arise during the selection of movement goals or during movement planning and execution. We demonstrate a behavioral and neural dissociation of these 2 types of conflict. During functional magnetic resonance imaging scanning, participants performed bimanual reaching movements with symmetric (congruent) or orthogonal (incongruent) trajectories. The required ...
متن کاملThe fast and the slow of skilled bimanual rhythm production: parallel versus integrated timing.
Professional pianists performed 2 bimanual rhythms at a wide range of different tempos. The polyrhythmic task required the combination of 2 isochronous sequences (3 against 4) between the hands; in the syncopated rhythm task successive keystrokes formed intervals of identical (isochronous) durations. At slower tempos, pianists relied on integrated timing control merging successive intervals bet...
متن کاملAn optically trapped mirror for reaching the standard quantum limit
The preparation of a mechanical oscillator driven by quantum back-action is a fundamental requirement to reach the standard quantum limit (SQL) for force measurement, in optomechanical systems. However, thermal fluctuating force generally dominates a disturbance on the oscillator. In the macroscopic scale, an optical linear cavity including a suspended mirror has been used for the weak force me...
