¹MNI305 space. Abbreviations: GWC, gray to white matter contrast; PD, Parkinson’s disease; MNI, Montreal Neurological Institute. Results were obtained using Monte Carlo simulation with 10.000 iterations applied to cortical thickness maps to provide cluster-wise correction for multiple comparisons (1.3, 2.0 and 4.0). Significant clusters were reported at p < 0.05.
