Abstract: Previous fMRI motor studies in Parkinson's disease (PD) have suggested that L-dopa may
``normalize'' areas of hypo- and hyperactivity. However, results from these studies, which were largely
based on analyzing BOLD signal amplitude, have been conflicting. Examining only amplitude changes
at distinct loci may thus be inadequate in fully capturing the activation changes induced by L-dopa. In
