  • Results are given as mean (SD). TP=Temporoparietal; contralateral=contralateral to worst clinically affected limbs in patients with Parkinson’s disease; ipsilateral=ipsilateral to worst clinically affected limbs in patients. All right, left, contralateral, and ipsilateral TP values for the patients were compared with the average of right and left TP values for the controls.

  • 2-150 p<0.05; **p<0.01 (Bonferroni correction) between controls and patients.
