List of the brain regions showing significantly more activity in normal subjects than in patients with Parkinson’s disease (Normal–Parkinson’s disease), or more activity in patients with Parkinson’s disease than in normal subjects (Parkinson’s disease–Normal), in performing in-phase movements (two sample t-test, P < 0.05, corrected). The coordinates are given as stereotaxic coordinates referring to the atlas of Talairach and Tournoux (1988).
