    • 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 ...

    • Dynamic switching between intrinsic and extrinsic mode networks as demands change from passive to active processing 

      Riemer, Frank; Gruner, Eli Renate; Beresniewicz, Justyna; Kazimierczak, Katarzyna Anna; Ersland, Lars; Hugdahl, Kenneth (Journal article; Peer reviewed, 2020-12-08)
      In this study we report on the relationship between default and extrinsic mode networks across alternating brief periods of rest and active task processing. Three different visual tasks were used in a classic fMRI ON–OFF ...

    • Dynamic up- and down-regulation of thedefault (DMN) and extrinsic (EMN) modenetworks during alternating task-on and task-offperiods 

      Hugdahl, Kenneth; Kazimierczak, Katarzyna Anna; Beresniewicz, Justyna; Kompus, Kristiina; Westerhausen, René; Ersland, Lars; Grüner, Renate; Specht, Karsten (Peer reviewed; Journal article, 2019)
      Using fMRI, Hugdahl et al. (2015) reported the existence of a general-domain cortical network during active task-processing which was non-specific to the cognitive task being processed. They labelled this network the ...

    • Hallucinating schizophrenia patients have longer left arcuate fasciculus fiber tracks: a DTI tractography study 

      Falkenberg, Liv E.; Westerhausen, René; Johnsen, Erik; Kroken, Rune Andreas; Løberg, Else-Marie; Beresniewicz, Justyna; Kazimierczak, Katarzyna Anna; Kompus, Kristiina; Ersland, Lars; Sandøy, Lydia Brunvoll; Hugdahl, Kenneth (Journal article; Peer reviewed, 2020)
      The arcuate fasciculus (AF) has been implicated in the pathology behind schizophrenia and auditory verbal hallucinations (AVHs). White matter tracts forming the arcuate fasciculus can be quantified and visualized using ...

    • Similarities and differences between intermittent and continuous resting-state fMRI 

      Beresniewicz, Justyna; Riemer, Frank; Kazimierczak, Katarzyna Anna; Ersland, Lars; Craven, Alexander R.; Hugdahl, Kenneth Jan; Grüner, Renate (Journal article; Peer reviewed, 2023)
      Introduction: Functional Magnetic Resonance Imaging (fMRI) block-design experiments typically include active ON-blocks with presentation of cognitive tasks which are contrasted with OFF- blocks with no tasks presented. ...

    • Simultaneous Measurement of the BOLD Effect and Metabolic Changes in Response to Visual Stimulation Using the MEGA-PRESS Sequence at 3 T 

      Dwyer, Gerard Eric; Craven, Alexander R.; Beresniewicz, Justyna; Kazimierczak, Katarzyna Anna; Ersland, Lars; Hugdahl, Kenneth Jan; Grüner, Eli Renate (Journal article; Peer reviewed, 2021)
      The blood oxygen level dependent (BOLD) effect that provides the contrast in functional magnetic resonance imaging (fMRI) has been demonstrated to affect the linewidth of spectral peaks as measured with magnetic resonance ...

    • Structural and functional largescale brain network dynamics: Examples from mental disorders 

      Beresniewicz, Justyna (Doctoral thesis, 2023-03-10)
      Hjernen er organisert i ulike funksjonelle og strukturelle nettverk. Til tross for omfattende forskning, er fremdeles ikke funksjonen og dynamikken i slike nettverk godt forstått. En økt innsikt kan være avgjørende for å ...

    • White matter microstructural differences between hallucinating and non-hallucinating schizophrenia spectrum patients 

      Beresniewicz, Justyna; Craven, Alexander R.; Hugdahl, Kenneth; Løberg, Else-Marie; Kroken, Rune Andreas; Johnsen, Erik; Gruner, Eli Renate (Journal article; Peer reviewed, 2021)
      The relation between auditory verbal hallucinations (AVH) and white matter has been studied, but results are still inconsistent. This inconsistency may be related to having only a single time-point of AVH assessment in ...
