Journal ArticleDOI
Reduced dopamine receptors and transporters but not synthesis capacity in normal aging adults: a meta-analysis.
Teresa M. Karrer,Anika K. Josef,Rui Mata,Evan D. Morris,Gregory R. Samanez-Larkin,Gregory R. Samanez-Larkin +5 more
TL;DR: This study precisely quantifies prior claims of reduced DA functionality with age and identifies presynaptic mechanisms (spared synthesis capacity and reduced DA transporters) that may partially account for previously unexplained phenomena whereby older adults appear to use dopaminergic resources effectively.
Journal ArticleDOI
A practical guide to methodological considerations in the controllability of structural brain networks.
Teresa M. Karrer,Jason Z. Kim,Jennifer Stiso,Ari E. Kahn,Fabio Pasqualetti,Ute Habel,Danielle S. Bassett +6 more
TL;DR: A systematic overview of the framework is provided, an alternative measure of structural connectivity is developed that accounts for radial propagation of activity through abutting tissue, and a complementary metric quantifying the complexity of the energy landscape of a system is defined.
Journal ArticleDOI
Subjective value representations during effort, probability and time discounting across adulthood.
Kendra L. Seaman,Nickolas Brooks,Teresa M. Karrer,Jaime J. Castrellon,Scott F. Perkins,Linh C. Dang,Ming Hsu,David H. Zald,Gregory R. Samanez-Larkin +8 more
TL;DR: It is suggested that while the tolerance of decision features is behaviorally dissociable, subjective value signals share a common representation across adulthood.
Journal ArticleDOI
Brain-based ranking of cognitive domains to predict schizophrenia.
Teresa M. Karrer,Danielle S. Bassett,Birgit Derntl,Oliver Gruber,André Aleman,Renaud Jardri,Angela R. Laird,Peter T. Fox,Peter T. Fox,Peter T. Fox,Simon B. Eickhoff,Olivier Grisel,Gaël Varoquaux,Bertrand Thirion,Danilo Bzdok,Danilo Bzdok +15 more
TL;DR: A data‐driven machine‐learning strategy is developed and a proof of principle is provided in a multisite clinical dataset how the ensuing meta‐analytic cognitive priors can distinguish patients and controls using brain morphology and intrinsic functional connectivity.
Journal ArticleDOI
Reduced serotonin receptors and transporters in normal aging adults: a meta-analysis of PET and SPECT imaging studies.
TL;DR: The findings overall identify reduced serotonergic signal transmission in healthy aging, which may partially explain psychological age differences, such as why older adults use more emotion-focused rather than problem-focused coping strategies.
