Classification of areas of significant hypoperfusion in pwPD group with respect to HC according to Mars' parietal atlas (41) and Sallet's dorsal-frontal atlas (40).
| ROI | Associated functions | Left mm3 (ppeak) | Right mm3 (ppeak) | |
|---|---|---|---|---|

| BA 10 | Involved in working memory and multiple-task coordination | - | - | |
| BA 46 | Involved in attention and working memory | - | - | |
 |
SPL A | Involved in motion processing using visual, tactile and auditory stimuli | - | - |
| SPL B | Involved in reaching movements and adjustments when following a moving target | - | - | |
| SPL C | Involved in visually guided hand movements and adjustments when intentions are updated | 16 (0.049) | 64 (0.049) | |
| SPL D | Involved in mechanisms of attention or task-switching related to the execution of manual responses | 896 (0.037) | - | |
| SPL E | Involved in the allocation of visual attention and in memorizing targets for intended eye movements | 936 (0.038) | - | |
 |
IPL A | Involved in tool use | - | - |
| IPL B | Involved in object manipulation | - | - | |
| IPL C | Involved in exploratory decisions and changes of response strategy | - | - | |
| IPL D | Involved in reorienting of attention and reorienting of saccades (anterior part of the angular gyrus) | 552 (0.037) | - | |
| IPL E | Involved in recognition memory (posterior part of the angular gyrus) | 816 (0.037) | - |
The cluster dimension in mm3 and the most significant FWE-corrected p-value within the cluster (ppeak) are reported.
BA, Brodmann area; CN, Caudate Nucleus; FWE, family wise error; HC, healthy controls; IPL, inferior parietal lobule; pwPD, people with Parkinson's disease; ROI, region of interest; SPL, superior parietal lobule.
