    • An Information-Theoretic Analysis of Resting-State versus Task fMRI 

      Tuominen, Julia Axiina; Specht, Karsten; Vaisvilaite, Liucija; Zeidman, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-20)
      Resting-state fMRI is an increasingly popular alternative to task-based fMRI. However, a formal quantification of the amount of information provided by resting-state fMRI as opposed to active task conditions about neural responses is lacking. We conducted a systematic comparison of the quality of inferences derived from a resting-state and a task fMRI paradigm by means of Bayesian Data Comparison. ...

    • Time of day dependent longitudinal changes in resting-state fMRI 

      Vaisvilaite, Liucija; Andersson, Micael; Salami, Alireza; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)
      Longitudinal studies have become more common in the past years due to their superiority over cross-sectional samples. In light of the ongoing replication crisis, the factors that may introduce variability in resting-state networks have been widely debated. This publication aimed to address the potential sources of variability, namely, time of day, sex, and age, in longitudinal studies within ...

    • Time-of-Day Effects in Resting-State Functional Magnetic Resonance Imaging: Changes in Effective Connectivity and Blood Oxygenation Level Dependent Signal 

      Vaisvilaite, Liucija; Hushagen, Vetle; Grønli, Janne; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-29)
      Introduction: In the light of the ongoing replication crisis in the field of neuroimaging, it is necessary to assess the possible exogenous and endogenous factors that may affect functional magnetic resonance imaging (fMRI). The current project investigated time-of-day effects in the spontaneous fluctuations (<0.1 Hz) of the blood oxygenation level dependent (BOLD) signal.<p> <p>Method: Using ...
