Journal ArticleDOI
The neural basis of perceptual bias and response bias in the Landmark task.
TL;DR: Investigation of lesion anatomy underlying perceptual and response bias using a manual response Landmark task in 68 patients with right-hemispheric stroke suggests that perceptual/attentional and motor/intentional aspects of neglect are independent components of the syndrome with differential neural underpinnings in fronto-parietal and subcortical brain regions.
Journal ArticleDOI
White matter lesions and the cholinergic deficit in aging and mild cognitive impairment
Nils Richter,Nils Richter,Anne Michel,Oezguer A. Onur,Lutz W. Kracht,Lutz W. Kracht,Markus Dietlein,Marc Tittgemeyer,Bernd Neumaier,Gereon R. Fink,Juraj Kukolja +10 more
TL;DR: Data suggest that the contribution of WML to the dysfunction of the cholinergic system in MCI due to AD depends on WML distribution, and AChE activity predicted memory function better than WML load, gray matter atrophy, or age.
Journal ArticleDOI
Disruption of the right temporoparietal junction impairs probabilistic belief updating
TL;DR: The causal involvement of the right temporoparietal junction (rTPJ) in updating probabilistic beliefs is shown and new insights into the chronometry of the process are provided by combining online transcranial magnetic stimulation (TMS) with computational modeling of behavioral responses.
Journal ArticleDOI
Imaging of Non— or Very Subtle Contrast-Enhancing Malignant Gliomas with [11C]-Methionine Positron Emission Tomography
Norbert Galldiks,Lutz W. Kracht,Veronika Dunkl,Roland T. Ullrich,Stefan Vollmar,Andreas H. Jacobs,Gereon R. Fink,Michael Schroeter +7 more
TL;DR: The present data suggest that in patients with WHO grade III glioma with minimal or a lack of contrast enhancement, MET-PET delineates metabolically active tumor tissue, and support the use of combined PET-MRI with radiolabeled amino acids (eg, MET) for the delineating of the true extent of active tumor in the diagnosis and treatment planning of patients with gliomas.
Journal ArticleDOI
An fMRI study into emotional processing in Parkinson's disease: Does increased medial prefrontal activation compensate for striatal dysfunction?
Anja J.H. Moonen,Peter H. Weiss,Michael Wiesing,Ralph Weidner,Gereon R. Fink,Jennifer Reijnders,Wim M. Weber,Albert F.G. Leentjens +7 more
TL;DR: The increased medial PFC activity may have modulated emotional responsiveness in patients via top-down cognitive control, therewith restoring emotional processing at the behavioral level, despite striatal dysfunction.
