      Voldsbekk, Irene; Bjørnerud, Atle; Groote, Inge Rasmus; Zak, Nathalia; Roelfs, Daniël; Maximov, Ivan; Geier, Oliver; Due-Tønnessen, Paulina; Bøen, Erlend; Kuiper, Yvonne S.; Løkken, Lise Linn; Strømstad, Marie; Blakstvedt, Taran Youssefian; Bjorvatn, Bjørn; Malt, Ulrik Fredrik; Westlye, Lars Tjelta; Elvsåshagen, Torbjørn; Grydeland, Håkon (Journal article; Peer reviewed, 2022)
      Cortical microstructure is influenced by circadian rhythm and sleep deprivation, yet the precise underpinnings of these effects remain unclear. The ratio between T1-weighted and T2-weighted magnetic resonance images (T1w/T2w ...
    • 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 ...
