      Ørbo, Marte Christine; Grønli, Ole Kristian; Larsen, Camilla; Vangberg, Torgil Riise; Friborg, Oddgeir; Turi, Zsolt; Mittner, Matthias Bodo; Csifcsak, Gabor; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-02)
      Background Intermittent theta burst stimulation (iTBS) when applied over the left dorsolateral prefrontal cortex (DLPFC) has been shown to be equally effective and safe to treat depression compared to traditional repetitive transcranial magnetic stimulation (rTMS) paradigms. This protocol describes a funded single-centre, double-blind, randomized placebo-controlled, clinical trial to investigate ...

    • Cerebral cortical thickness and surface area in adolescent anorexia nervosa: Separate and joint analyses with a permutation-based nonparametric method 

      Myrvang, Anna Dahl; Vangberg, Torgil Riise; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-17)
      <i>Objective</i> - Reduction in cerebral volume is often found in underweight patients with anorexia nervosa (AN), but few studies have investigated other morphological measures. Cortical thickness (CTh) and surface area (CSA), often used to produce the measure of cortical volume, are developmentally distinct measures that may be differentially affected in AN, particularly in the developing brain. ...
    • High-Definition Transcranial Direct Current Stimulation Improves Delayed Memory in Alzheimer’s Disease Patients: A Pilot Study Using Computational Modeling to Optimize Electrode Position 

      Rasmussen, Ingrid Daae; Boayue, Nya Mehnwolo; Mittner, Matthias; Bystad, Martin Kragnes; Grønli, Ole Kristian; Vangberg, Torgil Riise; Csifcsak, Gabor; Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-14)
      Background: The optimal stimulation parameters when using transcranial direct current stimulation (tDCS) to improve memory performance in patients with Alzheimer’s disease (AD) are lacking. In healthy individuals, inter-individual differences in brain anatomy significantly influence current distribution during tDCS, an effect that might be aggravated by variations in cortical atrophy in AD ...
    • Hippocampal Subfields in Adolescent Anorexia Nervosa 

      Myrvang, Anna Dahl; Vangberg, Torgil Riise; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-25)
      Patients with anorexia nervosa (AN) exhibit volume reduction in cerebral gray matter (GM), and several studies report reduced hippocampus volume. The hippocampal subfields (HS) are functionally and structurally distinct, and appear to respond differently to neuropathology. The aim of this study was to investigate HS volumes in adolescent females with restrictive AN compared to a healthy age-matched ...
    • The relation of hippocampal subfield volumes to verbal episodic memory measured by the California Verbal Learning Test II in healthy adults 

      Aslaksen, Per M; Bystad, Martin Kragnes; Ørbo, Marte; Vangberg, Torgil Riise (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-08)
      Total hippocampal volume has previously been shown to correlate with performance on tests for verbal episodic memory. However, there are sparse evidence on how hippocampal subfield volumes are related to verbal episodic memory in healthy adults. The present study investigated the association between volumes of separate hippocampal subfields and verbal episodic memory performance in healthy volunteers. ...
    • The role of moderating variables on BOLD fMRI response during semantic verbal fluency and finger tapping in active and educated healthy seniors 

      Rodriguez-Aranda, Claudia; Castro-Chavira, Susana A; Espenes, Ragna; Barrios, Fernando A.; Waterloo, Knut; Vangberg, Torgil Riise (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)
      Semantic verbal fluency is among the most employed tasks in cognitive aging research and substantial work is devoted to understanding the underlying mechanisms behind age-related differences at the neural and behavioral levels. The present investigation aimed to evaluate the role of moderating variables, such as age, sex, MMSE, and proxies of cognitive reserve (CR) on the hemodynamic response evoked ...
    • White matter correlates of gait perturbations resulting from spontaneous and lateralized attention in healthy older adults: A dual-task study 

      Castro Chavira, Susana Angelica; Vangberg, Torgil Riise; Gorecka, Marta Maria; Vasylenko, Olena; Waterloo, Knut; Rodriguez-Aranda, Claudia (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-18)
      To date the neural mechanisms behind gait perturbations caused by dual-task paradigms are still unknown. Therefore, the present study examined white matter correlates of gait perturbations caused by a dichotic listening task where spontaneous (free focus of attention) and lateralized attentional control (voluntary attention directed to right or left-ear) were tested. Fifty-nine right-handed, healthy ...
