    • Dynamic up- and down-regulation of the default (DMN) and extrinsic (EMN) mode networks during alternating task-on and task-off periods 

      Hugdahl, Kenneth; Kazimierczak, Katarzyna Anna; Beresniewicz, Justyna; Kompus, Kristiina; Westerhausen, René; Ersland, Lars; Grüner, Renate; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-19)
      Using fMRI, Hugdahl et al. (2015) reported the existence of a general-domain cortical network during active task-processing which was non-specific to the cognitive task being processed. They labelled this network the extrinsic mode network (EMN). The EMN would be predicted to be negatively, or anti-correlated with the classic default mode network (DMN), typically observed during periods of rest, ...

    • Glutamatergic modulation of auditory cortex connectivity with attentional brain networks in unpredictable perceptual environment 

      Kompus, Kristiina; Volehaugen, Vegard; Craven, Alexander R.; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-14)
      In a stable environment the brain can minimize processing required for sensory input by forming a predictive model of the surrounding world and suppressing neural response to predicted stimuli. Unpredicted stimuli lead to a prediction error signal propagation through the perceptual network, and resulting adjustment to the predictive model. The inter-regional plasticity which enables the model-building ...
