Generalization to local remappings of the visuomotor coordinate transformation.
During visually guided movement, visual representations of target location must be transformed into coordinates appropriate for movement. To investigate the representation and plasticity of the visuomotor coordinate transformation, we examined the changes in pointing behavior after local visuomotor remappings. The visual feedback of finger position was limited to one or two locations in the wor...

To investigate the representation and plasticity of the visuomotor coordinate transformation we examined the changes in pointing behavior subsequent to local remappings. The visual feedback of nger position was limited to one or two locations in the workspace, at which a discrepancy was introduced between the proprioceptively-and visually-perceived nger position. Such a local remapping induced ...
متن کاملHuman medial intraparietal cortex subserves visuomotor coordinate transformation.
In the macaque, the posterior parietal cortex (PPC) integrates multimodal sensory information for planning and coordinating complex movements. In particular, the areas around the intraparietal sulcus (IPS) serve as an interface between the sensory and motor systems to allow for coordinated movements in space. Because recent imaging studies suggest a comparable functional and anatomical organiza...
متن کاملComputational Structure of coordinate transformations: A generalization study
One of the fundamental properties that both neural networks and the central nervous system share is the ability to learn and generalize from examples. While this property has been studied extensively in the neural network literature it has not been thoroughly explored in human perceptual and motor learning. We have chosen a coordinate transformation system-the visuomotor map which transforms vi...
متن کاملGeneralization of Stochastic Visuomotor Rotations
Generalization studies examine the influence of perturbations imposed on one movement onto other movements. The strength of generalization is traditionally interpreted as a reflection of the similarity of the underlying neural representations. Uncertainty fundamentally affects both sensory integration and learning and is at the heart of many theories of neural representation. However, little is...
