Fig. 2. Postural instability/gait difficulty patients show increased activation within putamen after levodopa.

Extracted beta-weights from four striatal regions reflect BOLD activation during tapping > rest in each group. Compared to controls and TD ON, PIGD ON had significantly greater estimates from the posterior putamen contralateral to the tapping. None of the control, striatal regions showed significant differences. Error bars represent standard error of the mean. L = left; R = Right; pPut = posterior putamen; HCd = head of the caudate
