Fig. 3.
Location of peaks within the continuous shift versus the control condition. Coronal sections are shown. The anatomical MRI images shown are the average of T1 acquisitions transformed into stereotaxic space for each group in the intra-group analysis and for both groups in the inter-group analysis. (A) Intra-group analysis. The images display significant activation in the left dorsolateral PFC and the right posterior PFC in the Parkinson’s disease group, while none is observed in the control group. They also show larger activations in the patient group than in the control group bilaterally in the prestriate cortex. (B) Inter-group analysis. Images display significantly greater activity in the patient group versus the control group in the left dorsolateral PFC and the left prestriate cortex, while no significantly increased activity is observed in the control versus patient group subtraction.
