Journal ArticleDOI
Electrical Brain Stimulation Improves Cognitive Performance by Modulating Functional Connectivity and Task-Specific Activation
Marcus Meinzer,Daria Antonenko,Robert Lindenberg,Stefan Hetzer,Lena Ulm,Keren Avirame,Tobias Flaisch,Agnes Flöel +7 more
TL;DR: In conclusion, atDCS modulates endogenous low-frequency oscillations in a distributed set of functionally connected brain areas, possibly inducing more efficient processing in critical task-relevant areas and improved behavioral performance.
Journal ArticleDOI
Brain tissue properties differentiate between motor and limbic basal ganglia circuits
Ettore A. Accolla,Ettore A. Accolla,Juergen Dukart,Juergen Dukart,Gunther Helms,Nikolaus Weiskopf,Ferath Kherif,Antoine Lutti,Rumana Chowdhury,Stefan Hetzer,John-Dylan Haynes,Andrea A. Kühn,Bogdan Draganski,Bogdan Draganski +13 more
TL;DR: The demonstrated covariance pattern is interpreted as evidence for shared tissue properties within a functional circuit, which is closely linked to its function, and clearly segregates between motor and limbic basal ganglia circuits.
Journal ArticleDOI
Effects of spermidine supplementation on cognition and biomarkers in older adults with subjective cognitive decline (SmartAge)-study protocol for a randomized controlled trial.
Miranka Wirth,Claudia Schwarz,Gloria Benson,Nora Horn,Ralph Buchert,Catharina Lange,Theresa Köbe,Stefan Hetzer,Marta Maglione,Marta Maglione,Eva Michael,Eva Michael,Stefanie Märschenz,K Mai,K Mai,Ute A. Kopp,Dietmar Schmitz,Dietmar Schmitz,Ulrike Grittner,Stephan J. Sigrist,Stephan J. Sigrist,Stephan J. Sigrist,Slaven Stekovic,Frank Madeo,Agnes Flöel,Agnes Flöel +25 more
TL;DR: The SmartAge trial aims to provide evidence of the impact of spermidine supplementation on memory performance in older individuals with SCD, and identify possible neurophysiological mechanisms of action underlying the anticipated cognitive benefits.
Journal ArticleDOI
Perfusion alters stiffness of deep gray matter.
Stefan Hetzer,Patric Birr,Andreas Fehlner,Sebastian Hirsch,Florian Dittmann,Eric Barnhill,Jürgen Braun,Ingolf Sack +7 more
TL;DR: The distinct mechano-vascular properties of striatum tissue, as compared to the rest of DGM, may reflect elevated perfusion pressure, which could explain the well-known susceptibility of the putamen to hemorrhages.
Journal ArticleDOI
Personalized risk prediction of postoperative cognitive impairment - rationale for the EU-funded BioCog project.

TL;DR: The goal of this research and development project, which involves academic and industry partners throughout Europe, is to deliver a multivariate algorithm based on clinical assessments as well as molecular and neuroimaging biomarkers to overcome the currently unsatisfying situation.
