- Abstract
- Our ability to perform fast and accurate movements relies on multisensory feedback, including vision and proprioception. This thesis investigates multisensory integration during reaching movements when both noise and temporal delays impact the reliability of sensory information. We first demonstrate that the contribution of visual and proprioceptive feedback during movement are influenced by the demands of the motor task. Next, we show that multisensory movement corrections depend on the uncertainty and duration of visual feedback as well as on movement speed. Finally, we illustrate that the adaptation to visuomotor delays results in systematic changes in movement amplitudes, suggesting an update of spatial and/or temporal parameters in the brain’s internal model of the body dynamics. Taken together, our results highlight the complexity of multisensory movement control and provide directions for future research targeting neural correlates and clinical applications.
