Assessing brain structural associations with working-memory related brain patterns in schizophrenia and healthy controls using linked independent component analysis
Brandt, Christine Lycke; Doan, Nhat Trung; Tønnesen, Siren; Agartz, Ingrid; Hugdahl, Kenneth; Melle, Ingrid; Andreassen, Ole Andreas; Westlye, Lars Tjelta (Peer reviewed; Journal article, 2015)Schizophrenia (SZ) is a psychotic disorder with significant cognitive dysfunction. Abnormal brain activation during cognitive processing has been reported, both in task-positive and task-negative networks. Further, structural ... -
Brain age prediction reveals aberrant brain white matter in schizophrenia and bipolar disorder: A multi-sample diffusion tensor imaging study
Tønnesen, Siren; Kaufmann, Tobias; de Lange, Ann-Marie Glasø; Richard, Geneviève; Nhat Trung, Doan; Alnæs, Dag; van der Meer, Dennis; Rokicki, Jaroslav; Moberget, Torgeir; Maximov, Ivan; Agartz, Ingrid; Aminoff, Sofie Ragnhild; Beck, Dani; Barch, Deanna M.; Beresniewicz, Justyna; Cervenka, Simon; Fatouros-Bergman, Helena; Craven, Alexander R.; Flyckt, Lena; Gurholt, Tiril Pedersen; Haukvik, Unn Kristin H.; Hugdahl, Kenneth; Johnsen, Erik; Jönsson, Erik Gunnar; Schizophrenia Project (KaSP), Karolinska; Kolskår, Knut-Kristian; Kroken, Rune Andreas; Lagerberg, Trine Vik; Løberg, Else-Marie; Nordvik, Jan Egil; Sanders, Anne-Marthe; Ulrichsen, Kristine Moe; Andreassen, Ole Andreas; Westlye, Lars Tjelta (Journal article; Peer reviewed, 2020)Background Schizophrenia (SZ) and bipolar disorder (BD) share substantial neurodevelopmental components affecting brain maturation and architecture. This necessitates a dynamic lifespan perspective in which brain aberrations ... -
Considerations on brain age predictions from repeatedly sampled data across time
Korbmacher, Max; Wang, Mengyun; Eikeland, Rune; Buchert, Ralph; Andreassen, Ole; Espeseth, Thomas; Leonardsen, Esten Høyland; Westlye, Lars Tjelta; Maximov, Ivan; Specht, Karsten (Journal article; Peer reviewed, 2023)Introduction Brain age, the estimation of a person's age from magnetic resonance imaging (MRI) parameters, has been used as a general indicator of health. The marker requires however further validation for application in ... -
Longitudinal and cross-sectional investigations of long-term potentiation-like cortical plasticity in bipolar disorder type II and healthy individuals
Zak, Nathalia; Moberget, Torgeir; Bøen, Erlend; Boye, Birgitte; Waage, Trine Rygvold; Dietrichs, Espen; Harkestad, Nina; Malt, Ulrik Fredrik; Westlye, Lars Tjelta; Andreassen, Ole Andreas; Andersson, Stein; Elvsåshagen, Torbjørn (Peer reviewed; Journal article, 2018-05-24)Visual evoked potential (VEP) plasticity is a promising assay for noninvasive examination of long-term potentiation (LTP)-like synaptic processes in the cerebral cortex. We conducted longitudinal and cross-sectional ... -
Longitudinal stability of the brain functional connectome is associated with episodic memory performance in aging
Ousdal, Olga Therese; Kaufmann, Tobias; Kolskår, Knut-Kristian; Vik, Alexandra; Wehling, Eike; Lundervold, Astri; Lundervold, Arvid; Westlye, Lars Tjelta (Peer reviewed; Journal article, 2020)The brain functional connectome forms a relatively stable and idiosyncratic backbone that can be used for identification or “fingerprinting” of individuals with a high level of accuracy. While previous cross‐sectional ...
