Fig. 3: Target-specific differences in fractal dimension (FD) predictions.

Interaction plots for the predicted pre-to-post-DBS change in Parkinson’s medication (ΔLEDD) as a function of FD across selected brain regions, comparing globus pallidus internus (GPi) (dashed lines) and subthalamic nucleus (STN) (solid lines) targets. Slope values for each target are indicated on each plot. Source data are provided as a Source Data file.
