Locations and Peak Z Scores of Areas with rCBF Increase During STN Stimulation That Significantly Correlated with Motor Improvement (Motor Scores)
| Area | Coordinate | Z score | P | ||||
|---|---|---|---|---|---|---|---|
| x | y | z | |||||
| Right pre-SMA, medial BA6 | 14 | 10 | 60 | 3.34 | 0.000 | ||
| 14 | 0 | 48 | 3.17 | 0.001 | |||
| Right anterior cingulate cortex (BA32) | 8 | 4 | 42 | 3.07 | 0.001 | ||
Peak activations are localized according to left–right (x), anterior–posterior (y), and superior–inferior (z) coordinates of atlas by Talairach and Tournoux (27). Height threshold of P < 0.005 is uncorrected.
