      Background Electroconvulsive therapy (ECT) is associated with volumetric enlargements of corticolimbic brain regions. However, the pattern of whole-brain structural alterations following ECT remains unresolved. Here, we ...
    • The human amygdala encodes value and space during decision making 

      Ousdal, Olga Therese; Specht, Karsten; Server, Andres; Andreassen, Ole Andreas; Dolan, Ray J.; Jensen, Jimmy Kristian (Peer reviewed; Journal article, 2014-11-01)
      Valuable stimuli are invariably localized in space. While our knowledge regarding the neural networks supporting value assignment and comparisons is considerable, we lack a basic understanding of how the human brain ...
    • 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 ...
