Differences in unity: The go/no-go and stop signal tasks rely on different mechanisms
Raud, Liisa; Dooley, Niamh; Westerhausen, René; Huster, René J. (Journal article; Peer reviewed, 2020)Response inhibition refers to the suppression of prepared or initiated actions. Typically, the go/no-go task (GNGT) or the stop signal task (SST) are used interchangeably to capture individual differences in response ... -
Dynamic up- and down-regulation of thedefault (DMN) and extrinsic (EMN) modenetworks during alternating task-on and task-offperiods
Hugdahl, Kenneth; Kazimierczak, Katarzyna Anna; Beresniewicz, Justyna; Kompus, Kristiina; Westerhausen, René; Ersland, Lars; Grüner, Renate; Specht, Karsten (Peer reviewed; Journal article, 2019)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 ... -
From observed laterality to latent hemispheric differences: Revisiting the inference problem
Sørensen, Øystein; Westerhausen, René (Journal article; Peer reviewed, 2020)Researchers interested in hemispheric dominance frequently aim to infer latent functional differences between the hemispheres from observed lateral behavioural or brain-activation differences. To be valid, these inferences ... -
Impact of glutamate levels on neuronal response and cognitive abilities in schizophrenia
Falkenberg, Liv Eggset; Westerhausen, René; Craven, Alexander R.; Kroken, Rune A.; Løberg, Else-Marie; Specht, Karsten; Hugdahl, Kenneth (Peer reviewed; Journal article, 2014-04-02)Schizophrenia is characterized by impaired cognitive functioning, and brain regions involved in cognitive control processes show marked glutamatergic abnormalities. However, it is presently unclear whether aberrant neuronal ... -
Resting States Are Resting Traits – An fMRI Study of Sex Differences and Menstrual Cycle Effects in Resting State Cognitive Control Networks
Hjelmervik, Helene; Hausmann, Markus; Osnes, Berge; Westerhausen, René; Specht, Karsten (Peer reviewed; Journal article, 2014-07-24)To what degree resting state fMRI is stable or susceptible to internal mind states of the individual is currently an issue of debate. To address this issue, the present study focuses on sex differences and investigates ... -
The role of the primary auditory cortex in the neural mechanism of auditory verbal hallucinations
Kompus, Kristiina; Falkenberg, Liv Eggset; Bless, Josef J; Johnsen, Erik; Kroken, Rune; Kråkvik, Bodil; Larøi, Frank; Løberg, Else-Marie; Vedul-Kjelsås, Einar; Westerhausen, René; Hugdahl, Kenneth (Peer reviewed; Journal article, 2013-04-24)Auditory verbal hallucinations (AVHs) are a subjective experience of “hearing voices” in the absence of corresponding physical stimulation in the environment. The most remarkable feature of AVHs is their perceptual quality, ... -
Self-supervised, mobile-application based cognitive training of auditory attention: A behavioral and fMRI evaluation
Bless, Josef J; Westerhausen, René; Kompus, Kristiina; Gudmundsen, Magne; Hugdahl, Kenneth; Hugdahl, Kenneth (Peer reviewed; Journal article, 2014-07)Emerging evidence of the validity of collecting data in natural settings using smartphone applications has opened new possibilities for psychological assessment, treatment, and research. In this study we explored the ...
