Figure 2.

A–C, Group difference in RAC binding at rest (A) and its change (mean percentage ΔBP) during symptomatic speech production (B) and asymptomatic sequential finger tapping (C). The color bars represent the t values and reflect the significance of changes in striatal RAC BP measures in spasmodic dysphonia patients compared to healthy controls (spasmodic dysphonia < healthy control, dark blue to light blue; spasmodic dysphonia > healthy control, yellow to red). All statistical maps are shown in the series of coronal brain images in Talairach-Tournoux standard space.
