    • 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; Tidsskriftartikkel; Peer reviewed, 2023-08-16)
      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 clinical contexts. Here, we show how brain age predictions perform for the same individual at various time points and validate our findings with age-matched healthy controls.<p> ...

    • Deep brain imaging of three participants across 1 year: The Bergen breakfast scanning club project 

      Wang, Meng-yun; Korbmacher, Max; Eikeland, Rune Andreas; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-17)
      Our understanding of the cognitive functions of the human brain has tremendously benefited from the population functional Magnetic Resonance Imaging (fMRI) studies in the last three decades. The reliability and replicability of the fMRI results, however, have been recently questioned, which has been named the replication crisis. Sufficient statistical power is fundamental to alleviate the crisis, ...

    • A global experiment on motivating social distancing during the COVID-19 pandemic 

      Legate, Nicole; Nguyen, Thuy-vy; Weinstein, Netta; Lund, Maria Louise; Klevjer, Kristoffer; Kunst, Jonas R.; Pfuhl, Gerit; Schei, Vidar; Korbmacher, Max; Tamnes, Christian Krog; Bundt, Carsten; Askelund, Adrian Dahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-27)
      Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an ...

    • The intra-individual reliability of 1H-MRS measurement in the anterior cingulate cortex across 1 year 

      Wang, Mengyun; Korbmacher, Max; Eikeland, Rune; Craven, Alexander R.; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-20)
      Magnetic resonance spectroscopy (MRS) is the primary method that can measure the levels of metabolites in the brain in vivo. To achieve its potential in clinical usage, the reliability of the measurement requires further articulation. Although there are many studies that investigate the reliability of gamma-aminobutyric acid (GABA), comparatively few studies have investigated the reliability of ...

    • A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic 

      Wang, Ke; Kunst, Jonas R.; Tamnes, Christian Krog; Schei, Vidar; Sverdrup, Therese E.; Askelund, Adrian Dahl; Pfuhl, Gerit; Klevjer, Kristoffer; Korbmacher, Max; Bundt, Carsten; Goldberg, Amit; Dorison, Charles A.; Miller, Jeremy K.; Uusberg, Andero; Lerner, Jennifer; Gross, James J; Agesin, Bamikole Bamikole; Bernardo, Marcia; Campos, Olatz; Eudave, Luis; Grzech, Karolina; Ozery, Daphna Hausman; Garcia, Elkin Oswaldo Luis; Jackson, Emily A.; Drexler, Shira Meir; Jurkovic, Anita Penic; Rana, Kafeel; Wilson, John Paul; Antoniadi, Maria; Desai, Kermeka; Gialitaki, Zoi; Kushnir, Elizaveta; Nadif, Khaoula; Bravo, Olalla Nino; Nauman, Rafia; Oosterlinck, Marlies; Pantazi, Myrto; Pilecka, Natalia; Szabelska, Anna; van Steenkiste, I.M.M.; Filip, Katarzyna; Bozdoc, Andrea Ioana; Marcu, Gabriela Mariana; Agadullina, Elena; Adamkovic, Matus; Roczinewska, Marta; Reyana, Cecilia; Kassianos, Angelos P.; Westerlund, Minja; Ahlgren, Lina; Pöntinen, Sara (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-02)
      The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and ...
