  • Evidence for widespread alterations in cortical microstructure after 32 h of sleep deprivation 
    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 / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract Cortical microstructure is influenced by circadian rhythm and sleep deprivation, yet the precise underpinnings of these effects remain unclear. The ratio between T 1 -weighted and T 2 -weighted magnetic resonance ...
  • MRI based detection of time-of-day variation in white matter microstructure - are more complex diffusion models better? 
    Løkken, Lise Linn (Master thesis / Masteroppgave, 2019)
    Diffusion Weighted Imaging (DWI) is a MRI technique probing the diffusion of water molecules in the human body. Its ability to measure structural and functional changes beyond the nominal image resolution level, has made ...
  • Sleep and sleep deprivation differentially alter white matter microstructure: A mixed model design utilising advanced diffusion modelling 
    Voldsbekk, Irene; Groote, Inge Rasmus; Zak, Nathalia; Roelfs, Daniël Thomas Heimen; Geier, Oliver; Due-Tønnessen, Paulina; Løkken, Lise Linn; Strømstad, Marie; Blakstvedt, Taran Y; Kuiper, Yvonne S; Elvsåshagen, Torbjørn; Westlye, Lars Tjelta; Bjørnerud, Atle; Maximov, Ivan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Sleep deprivation influences several critical functions, yet how it affects human brain white matter (WM) is not well understood. The aim of the present work was to investigate the effect of 32 hours of sleep deprivation ...
