Figure 5. Group-level response (ON-OFF) of PD patients to levodopa treatment.

Figure 5

Uncorrected threshold of p<0.001 was adopted and maps were overlaid on coronal and axial slices (left, blue: group maps obtained by standard first-level modeling without further assumptions on motor performance; right, orange: improvement of group-level maps obtained using various kinematic modeling techniques taking movement performance into account). AI - amplitude invariant.
