      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. ...

      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 ...
