Journal ArticleDOI
Structure–Function Correlates of Cognitive Decline in Aging
Jonas Persson,Lars Nyberg,Johanna Lind,Anne Larsson,Lars-Göran Nilsson,Martin Ingvar,Randy L. Buckner +6 more
TL;DR: In this paper, structural and diffusion tensor imaging (DTI) revealed a heterogeneous set of differences associated with cognitive decline in aging, and suggested that increased activation is either caused by structural disruption or is a compensatory response to such disruption.
Journal ArticleDOI
Age Differences in Deactivation: A Link to Cognitive Control?
TL;DR: Demand-related changes in deactivation magnitude correlated with performance changes, suggesting that individual and group differences in de activation have functional significance.
Journal ArticleDOI
Longitudinal evidence for diminished frontal cortex function in aging
Lars Nyberg,Alireza Salami,Mikael Andersson,Johan G. Eriksson,Grégoria Kalpouzos,Karolina Kauppi,Johanna Lind,Sara Pudas,Jonas Persson,Lars-Göran Nilsson +9 more
TL;DR: These findings dispute inferences of true age changes on the basis of age differences, hence challenging some contemporary models of neurocognitive aging, and demonstrate age-related decline in frontal brain volume as well as functional response.
Journal ArticleDOI
Common prefrontal activations during working memory, episodic memory, and semantic memory
Lars Nyberg,Petter Marklund,Jonas Persson,Roberto Cabeza,Christian Forkstam,Karl Magnus Petersson,Martin Ingvar +6 more
TL;DR: Compared the activation patterns associated with tests of working memory, semantic memory and episodic memory, the results converged on a general involvement of four regions across memory tests, providing evidence that some PFC regions are engaged during many different memory tests.
Journal ArticleDOI
Identification of vulnerable plaques and patients by intracoronary near-infrared spectroscopy and ultrasound (PROSPECT II): a prospective natural history study
David Erlinge,Akiko Maehara,Ori Ben-Yehuda,Hans Erik Bøtker,Michael Maeng,Lars Kjøller-Hansen,Thomas Engstrøm,Mitsuaki Matsumura,Aaron Crowley,Ovidiu Dressler,Gary S. Mintz,Ole Fröbert,Jonas Persson,Rune Wiseth,Alf Inge Larsen,Lisette Okkels Jensen,Jan Erik Nordrehaug,Øyvind Bleie,Elmir Omerovic,Claes Held,Stefan James,Ziad A. Ali,James E. Muller,Gregg W. Stone,Prospect Ii Investigators +24 more
TL;DR: The PROSPECT II clinical trial as discussed by the authors showed that combined NIRS and intravascular ultrasound can identify high-risk plaques and patients that are at risk for future major adverse cardiac events (MACEs).
