A Comparison of VDC and pallidum volumes between patients with and without FOG in cohort 1. B Comparison of VDC and pallidum volumes at baseline between patients with and without FOG development in PPMI cohort. C Comparison of VDC and pallidum volumes at four-year follow-up between patients with and without FOG development in PPMI cohort. FOG freezing of gait, VDC ventral diencephalon.
