Journal ArticleDOI
Mesolimbic Functional Magnetic Resonance Imaging Activations during Reward Anticipation Correlate with Reward-Related Ventral Striatal Dopamine Release
Björn H. Schott,Luciano Minuzzi,Ruth M. Krebs,David Elmenhorst,Markus Lang,Oliver H. Winz,Constanze I. Seidenbecher,Heinz H. Coenen,Hans-Jochen Heinze,Karl Zilles,Emrah Düzel,Andreas Bauer +11 more
TL;DR: Evidence is provided that dopaminergic neurotransmission plays a quantitative role in human mesolimbic reward processing and the combined neurochemical and hemodynamic imaging approach used here opens up new perspectives for the investigation of molecular mechanisms underlying human cognition.
Journal ArticleDOI
Sleep Deprivation Increases A1 Adenosine Receptor Binding in the Human Brain: A Positron Emission Tomography Study
David Elmenhorst,Philipp T. Meyer,Oliver H. Winz,Andreas Matusch,Johannes Ermert,Heinz H. Coenen,Radhika Basheer,Helmut L. Haas,Karl Zilles,Andreas Bauer +9 more
TL;DR: This is the first molecular imaging study that provides in vivo evidence for an A1 AR upregulation in cortical and subcortical brain regions after prolonged wakefulness, indicating that A1AR expression is contributing to the homeostatic sleep regulation.
Journal ArticleDOI
[18F]FDG-PET is superior to [123I]IBZM-SPECT for the differential diagnosis of parkinsonism
Sabine Hellwig,Florian Amtage,Annabelle Kreft,Ralph Buchert,Oliver H. Winz,Werner Vach,Timo S. Spehl,Michel Rijntjes,Bernhard Hellwig,Cornelius Weiller,Christian Winkler,Wolfgang Weber,Oliver Tüscher,Philipp T. Meyer +13 more
TL;DR: The diagnostic accuracy of [18F]FDG-PET for discriminating LBD from APS is considerably higher than for [123I]IBZM-SPECT, and this approach reliably differentiates APS subgroups.
Journal ArticleDOI
5-HT2A receptor density is decreased in the at-risk mental state.
René Hurlemann,Andreas Matusch,Kai-Uwe Kühn,Julia Berning,David Elmenhorst,Oliver H. Winz,Heike Kölsch,Karl Zilles,Michael Wagner,Wolfgang Maier,Andreas Bauer +10 more
TL;DR: These findings substantiate the rationale for establishing a phase-specific psychopharmacological intervention in the ARMS that addresses the serotonergic component of vulnerability to schizophrenia.
Journal ArticleDOI
Caffeine Occupancy of Human Cerebral A1 Adenosine Receptors: In Vivo Quantification with 18F-CPFPX and PET
David Elmenhorst,Philipp T. Meyer,Andreas Matusch,Oliver H. Winz,Andreas Bauer,Andreas Bauer +5 more
TL;DR: Caffeine might occupy up to 50% of the cerebral A1AR when caffeinated beverages are repeatedly consumed during a day, and 18F-CPFPX PET is suitable for studying the cerebral actions of caffeine, the most popular neurostimulant worldwide.
