abstract = {To examine the mechanisms of functional bimanual
synchronization in goal-directed movements, we studied the
movement kinematics of motorically unimpaired subjects while
they performed repetitive prehension movements (either
unimanually or bimanually) to small food items. Compared to
unimanual conditions, bimanual movement execution yielded a
significantly prolonged mouth contact phase. We hypothesized
that this threefold prolongation led to a proper functional
synchronization of the movement onsets of both hands at the
beginning of each new movement cycle. That these temporal
adjustments occurred in the movement phase with maximal
haptic input points to the importance of sensory feedback
for bimanual coordination. These results are discussed with
respect to the important role of sensory feedback in the
timing of coordinated bimanual movements. Furthermore, we
propose that time-based coordinating schemas, which are
implemented by the cerebellum and the posterior parietal
cortex using sensory feedback, underlie functional
inter-limb coordination.},
