    • Combined fMRI region- and network-analysis reveal new insights of top-down modulation of bottom-up processes in auditory laterality 

      Kazimierczak, Katarzyna; Craven, Alexander R.; Ersland, Lars; Specht, Karsten; Dumitru, Magda L.; Sandøy, Lydia B.; Hugdahl, Kenneth (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-18)
      Dichotic listening along with the right-ear advantage (REA) has been a standard method of investigating auditory laterality ever since it was first introduced into neuropsychology in the early 1960s. Beginning in the 1980s, authors reported that it was possible to modulate the bottom-up driven perceptual REA by instructing subjects to selectively attend to and report only from the right or left ...

    • 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, ...
