Moderne Helsebekymringer
(Master thesis, 2002)Objective: In a previous study in New Zealand, the newly developed Modern Health Worries Scale (MHW) was significantly correlated with Subjective Health Complaints (SHC) and health care utilization. The aim of the present ... -
Modular-Level Functional Connectome Alterations in Individuals With Hallucinations Across the Psychosis Continuum
(Journal article; Peer reviewed, 2022)Functional connectome alterations, including modular network organization, have been related to the experience of hallucinations. It remains to be determined whether individuals with hallucinations across the psychosis ... -
MRI measures of brain volume and cortical complexity in clinical groups and during development
(Doctoral thesis, 2009-05-07)The complex structure of the surface of the brain might elude classical magnetic resonance imaging (MRI) methods of characterization, when it comes to measures of surface irregularities. Such measures may be important when ... -
Multi-vendor standardized sequence for edited magnetic resonance spectroscopy
(Peer reviewed; Journal article, 2019)Spectral editing allows direct measurement of low-concentration metabolites, such as GABA, glutathione (GSH) and lactate (Lac), relevant for understanding brain (patho)physiology. The most widely used spectral editing ... -
A multimodal study of the effects of tDCS on dorsolateral prefrontal and temporo-parietal areas during dichotic listening
(Journal article; Peer reviewed, 2020)The underlying neural mechanisms of transcranial direct current stimulation (tDCS), especially beyond the primary motor cortex, remain unclear. Several studies examined tDCS effects on either functional activity, ... -
The "myths" of low back pain: status quo in norwegian general practitioners and physiotherapists
(Peer reviewed; Journal article, 2004)Background. In 2001, several myths of low back pain still were alive in the general population in Norway, myths that were not in concordance with current guidelines. Objectives. To investigate perceptions about back pain ... -
Negative valence of hallucinatory voices as predictor of cortical glutamatergic metabolite levels in schizophrenia patients
(Journal article; Peer reviewed, 2021)Objectives Negative emotional valence of auditory verbal hallucinations (AVHs) in schizophrenia can be a source of distress and is considered a strong predictor of illness severity. Previous studies have found glutamate ... -
Neocortical substrates of feelings evoked with music in the ACC, insula, and somatosensory cortex
(Journal article; Peer reviewed, 2021)Neurobiological models of emotion focus traditionally on limbic/paralimbic regions as neural substrates of emotion generation, and insular cortex (in conjunction with isocortical anterior cingulate cortex, ACC) as the ... -
A network module for the perseus software for computational proteomics facilitates proteome interaction graph analysis
(Peer reviewed; Journal article, 2019-04-01)Proteomics data analysis strongly benefits from not studying single proteins in isolation but taking their multivariate interdependence into account. We introduce PerseusNet, the new Perseus network module for the biological ... -
Neural activation in the ventromedial prefrontal cortex precedes conscious experience of being in or out of a transient hallucinatory state
(Journal article; Peer reviewed, 2022)Background and Hypotheses Auditory verbal hallucinations (AVHs) is not only a common symptom in schizophrenia but also observed in individuals in the general population. Despite extensive research, AVHs are poorly understood, ... -
The neural correlates of sex differences in left-right confusion
(Peer reviewed; Journal article, 2015-03-14)Difficulties in left–right discrimination (LRD) are commonly experienced in everyday life situations. Here we investigate the neurocognitive mechanisms of LRD and the specific role of left angular gyrus. Given that previous ... -
Neural plasticity in functional and anatomical MRI studies of children with Tourette syndrome
(Peer reviewed; Journal article, 2013)Background: Tourette syndrome (TS) is a neuropsychiatric disorder with childhood onset characterized by chronic motor and vocal tics. The typical clinical course of an attenuation of symptoms during adolescence in parallel ... -
Neurocognitive Development and Predictors of L1 and L2 Literacy Skills in Dyslexia: A Longitudinal Study of Children 5–11 Years Old
(Peer reviewed; Journal article, 2015-10-29)The aim of this study was to find valid neurocognitive precursors of literacy development in first language (L1, Norwegian) and second language (L2, English) in a group of children during their Pre-literacy, Emergent ... -
Neuronal underpinnings of stuttering
(Master thesis, 2016-05-24)Fluent speech production depends on robust connections between brain regions that are crucial for auditory processing, motor planning and execution. The ability of the speech apparatus to produce effortless, continuous and ... -
The neurophysiological correlates of religious chanting
(Peer reviewed; Journal article, 2019-03-12)Despite extensive research on various types of meditation, research on the neural correlates of religious chanting is in a nascent stage. Using multi-modal electrophysiological and neuroimaging methods, we illustrate that ... -
Neuroplastic effects in patients with traumatic brain injury after music-supported therapy
(Peer reviewed; Journal article, 2019)Damage to the orbitofrontal cortex (OFC) often occurs following a traumatic brain injury (TBI) and can lead to complex behavioral changes, including difficulty with attention and concentration. We investigated the effects ... -
Neuropsychological functioning in a national cohort of severe traumatic brain injury: demographic and acute injury-related predictors
(Peer reviewed; Journal article, 2015)Objectives: To determine the rates of cognitive impairment 1 year after severe traumatic brain injury (TBI) and to examine the influence of demographic, injury severity, rehabilitation, and subacute functional outcomes on ... -
New Approaches to the Use of Magnetic Resonance Spectroscopy for Investigating the Pathophysiology of Auditory-Verbal Hallucinations
(Doctoral thesis, 2019-10-09)Magnetic resonance imaging (MRI) may be considered one of the most useful technological developments in the field of cognitive neuroscience. Above the ability to provide detailed anatomical images, MRI has afforded researchers ... -
No Effects of Anodal tDCS on Local GABA and Glx Levels in the Left Posterior Superior Temporal Gyrus
(Peer reviewed; Journal article, 2019-01-08)A number of studies investigating the biological effects of transcranial direct current stimulation (tDCS) using magnetic resonance spectroscopy (MRS) have found that it may affect local levels of γ-aminobutyric acid (GABA), ... -
No escaping the rat race: simulated night shift work alters the time-of-day variation in BMAL1 translational activity in the prefrontal cortex
(Peer reviewed; Journal article, 2017-10-04)Millions of people worldwide work during the night, resulting in disturbed circadian rhythms and sleep loss. This may cause deficits in cognitive functions, impaired alertness and increased risk of errors and accidents. ...
