Journal ArticleDOI
Role of the posterior parietal cortex in updating reaching movements to a visual target.
Michel Desmurget,Michel Desmurget,Charles M. Epstein,Robert Turner,Claude Prablanc,G. E. Alexander,Scott T. Grafton +6 more
TL;DR: Transcranial magnetic stimulation was applied over the left PPC during target presentation and disrupted path corrections that normally occur in response to target jumps, but had no effect on those directed at stationary targets.
Journal ArticleDOI
Functional anatomy of nonvisual feedback loops during reaching: a positron emission tomography study.
Michel Desmurget,Helena Grea,Helena Grea,Jeffrey S. Grethe,Claude Prablanc,G. E. Alexander,Scott T. Grafton +6 more
TL;DR: PET difference images showed that corrections made in the reaching condition involving large corrections were mediated by a restricted network involving the left posterior parietal cortex, the right anterior intermediate cerebellum, and the left primary motor cortex, consistent with knowledge of the functional properties of these areas.
Journal ArticleDOI
Constrained and Unconstrained Movements Involve Different Control Strategies
TL;DR: The data support the hypothesis that unconstrained motions are, unlike compliant motions, not programmed to follow a straight-line path in the task space, and suggest that compliant and unconStrained movements involve different control strategies.
Journal ArticleDOI
Pointing Errors Reflect Biases in the Perception of the InitialHand Position
TL;DR: Pointing errors reflect to a significant extent the erroneous estimation of initial hand position, which suggests that aimed hand movements are planned vectorially, i.e., in terms of distance and direction, rather than in Terms of absolute position in space.
Journal ArticleDOI
Postural Control of Three-Dimensional Prehension Movements
TL;DR: The hypothesis that three-dimensional upper limb movements could be initiated and controlled in the joint space via a mechanism comparing an estimate of the current postural state of the upper arm with a target value determined by one specific inverse static transform converting the coordinates of the object into a set of arm, forearm, and wrist angles is supported.
