Significant (pcorr <0.05) activation responses during the execution of an externally cued repetitive reaching task (see text). The surface rendering of the statistical map (SPM 99 canonical template) reflects the main effect of the task in 13 early stage PD patients scanned at baseline and at 2 years follow-up. The motor activation response was localized to the primary (sensorimotor cortex, SMC) and secondary motor areas (premotor cortex, PMC; and supplementary motor area, SMA) and to parietal (PAR) and occipital association cortices (OCC). Significant cerebellar and basal ganglia activation responses were also present.
