Results of correlation analysis between mean reaction time (RT) and dopaminergic activity as assessed through ¹⁸F-DOPA PET in de novo Parkinson's disease patients.

Analysis	Cluster level			Peak level
	Cluster extent	Corrected p value	Cortical region	Maximum Z score	Talairach coordinates			Cortical region	BA
RT	126	0.05	L-frontal	6.02	−42	40	−19	Middle frontal gyrus	11
			L-frontal	5.59	−46	30	−17	Inferior frontal gyrus	47
			L-temporal	4.83	−48	20	−20	Superior temporal gyrus	38

Uncorrected p < 0.001 at peak level and p < 0.05, false discovery rate corrected at cluster level, were accepted as statistically significant. In the “cluster level” section on the left, for each cluster found to be statistically significant are reported the number of voxels, the corrected p value, and the cortical region where the cluster is found. In the “peak level” section on the right, for each significant cluster are reported the peak coordinates and Z score, the corresponding cortical region and Brodmann area (BA).
