Figure 2.
Relative cerebral blood flow (CBF) change between baseline and post-medication (calculated as post-medication CBF minus baseline CBF) in predefined regions of interest (ROIs) located in the caudate, putamen, globus pallidus and thalamus. Each ROI comprised the full extent of the structure. Values are the mean of 18 subjects. Error bars represent the SD. *Indicates significant differences between metoclopramide changes and placebo changes (P < 0.05). Absolute CBF values were converted to relative CBF by adjusting the global CBF to a fixed value of 50 mL·100 g−1·min−1. L, left; R, right.
