abstract = {Patients suffering from Parkinson's disease (PD) often show
impairments in executive function (EF) like decision-making
and action control. The right dorsolateral prefrontal cortex
(dlPFC) has been strongly implicated in EF in healthy
subjects and has repeatedly been reported to show
alterations related to EF impairment in PD. Recently, two
key regions for cognitive action control have been
identified within the right dlPFC by co-activation based
parcellation. While the posterior region is engaged in
rather basal EF like stimulus integration and working
memory, the anterior region has a more abstract, supervisory
function. To investigate whether these functionally distinct
subdivisions of right dlPFC are differentially affected in
PD, we analyzed resting-state functional connectivity (FC)
in 39 PD patients and 44 age- and gender-matched healthy
controls. Patients were examined both after at least 12 h
withdrawal of dopaminergic drugs (OFF) and under their
regular dopaminergic medication (ON). We found that only the
posterior right dlPFC subdivision shows FC alterations in
PD, while the anterior part remains unaffected. PD-related
decreased FC with posterior right dlPFC was found in the
bilateral medial posterior parietal cortex (mPPC) and left
dorsal premotor region (PMd) in the OFF state. In the
medical ON, FC with left PMd normalized, while decoupling
with bilateral mPPC remained. Furthermore, we observed
increased FC between posterior right dlPFC and the bilateral
dorsomedial prefrontal cortex (dmPFC) in PD in the ON state.
Our findings point to differential disturbances of right
dlPFC connectivity in PD, which relate to its hierarchical
organization of EF processing by stronger affecting the
functionally basal posterior aspect than the hierarchically
higher anterior part.},
