abstract = {Background: Motor-related brain activity in Parkinson's
disease has been investigated in a multitude of functional
neuroimaging studies, which often yielded apparently
conflicting results. Our previous meta-analysis did not
resolve inconsistencies regarding cortical activation
differences in Parkinson's disease, which might be related
to the limited number of studies that could be included.
Therefore, we conducted a revised meta-analysis including a
larger number of studies. The objectives of this study were
to elucidate brain areas that consistently show abnormal
motor-related activation in Parkinson's disease and to
reveal their functional connectivity profiles using
meta-analytic approaches.Methods: We applied a quantitative
meta-analysis of functional neuroimaging studies testing
limb movements in Parkinson's disease comprising data from
39 studies, of which 15 studies (285 of 571 individual
patients) were published after the previous meta-analysis.
We also conducted meta-analytic connectivity modeling to
elucidate the connectivity profiles of areas showing
abnormal activation.Results: We found consistent
motor-related underactivation of bilateral posterior putamen
and cerebellum in Parkinson's disease. Primary motor cortex
and the supplementary motor area also showed deficient
activation, whereas cortical regions localized directly
anterior to these areas expressed overactivation.
Connectivity modeling revealed that areas showing decreased
activation shared a common pathway through the posterior
putamen, whereas areas showing increased activation were
connected to the anterior putamen.Conclusions: Despite
conflicting results in individual neuroimaging studies, this
revised meta-analytic approach identified consistent
patterns of abnormal motor-related activation in Parkinson's
disease. The distinct patterns of decreased and increased
activity might be determined by their connectivity with
different subregions of the putamen. © 2021 The Authors.
