Dopaminergic effects on the implicit processing of distractor objects in Parkinson's disease.

abstract：:The parietal lobes contribute to body-space representation. The present work aims at characterizing the functional role of the inferior parietal lobe in body-space representation and at studying the different roles of the angular gyrus in the right and left hemisphere. We conducted three separate transcranial direct c...
