Criminal responsibility and mental disorder
This paper discusses some problems in associating definitions and judgments of criminal unaccountability, e.g. criminal insanity, to psychiatric constructs, i.e., diagnoses, symptoms and related constructs of functional impairment. The aim is to highlight this relationship as to why it is inevitably challenging at a conceptual level. The backdrop of the paper is that the dependence between legal and psychiatric constructs challenges constitutiona…
When fMRI came to Bergen and Norway – as I remember it
In this personal recollection, I review the beginning of functional magnetic resonance imaging (fMRI) research in Norway, i.e., at the University of Bergen and the Haukeland University Hospital in Bergen. Research with fMRI had already started in Bergen in 1993, and the small group of researchers involved were the first to take up this new method for studies of the brain and brain‐behavior relationships. This article is a recollection of the earl…
Mapping psychotic‐like experiences
Suggestions have been made that psychotic‐like experiences (PLEs), such as hallucinatory and delusional experiences, exist on a continuum from healthy individuals to patients with a diagnosis of schizophrenia. We used the screening questions of the Questionnaire for Psychotic Experiences (QPE), an interview that captures the presence and phenomenology of various psychotic experiences separately, to assess PLEs in Norway. Based on data from an onl…
Glutamate- and Gaba-Modulated Connectivity in Auditory Hallucinations—A Combined Resting State fMRI and MR Spectroscopy Study
Background: Auditory verbal hallucinations (AVH) have been linked to aberrant interhemispheric connectivity between the left and the right superior temporal gyrus (STG), labeled the interhemispheric miscommunication theory. The present study investigated if interhemispheric miscommunication is modulated at the neurochemical level by glutamate (Glu) and gamma-aminobutyric acid (GABA) concentrations in temporal and prefrontal lobe areas, as propose…
Dynamic Functional Connectivity Patterns in Schizophrenia and the Relationship With Hallucinations
There is a wealth of evidence showing aberrant functional connectivity (FC) in schizophrenia but with considerable variability in findings across studies. Dynamic FC is an extension of traditional static FC, in that such analyses allow for explorations of temporal changes in connectivity. Thereby they also provide more detailed information on connectivity abnormalities in psychiatric disorders such as schizophrenia. The current study investigated…
Psychopathology Assessment Methods Revisited
We present in this article a study design that combines clinical self-assessment scale, simultaneously administered with fMRI data acquisition. We have used a standard block-design with two different conditions. Each active block consisted of four text statements (items), alternating diagnostically specific (DS) blocks comprising items from von Zerssen depression scale and diagnostically neutral (DN) blocks with items from a questionnaire about g…
Dichotic Listening and Language
Cognitive control of speech perception across the lifespan
The ability to use cognitive-control functions to regulate speech perception is thought to be crucial in mastering developmental challenges, such as language acquisition during childhood or compensation for sensory decline in older age, enabling interpersonal communication and meaningful social interactions throughout the entire life span. Although previous studies indicate that cognitive control of speech perception is subject to developmental c…
Development of attentional control of verbal auditory perception from middle to late childhood
Multitalker situations confront listeners with a plethora of competing auditory inputs, and hence require selective attention to relevant information, especially when the perceptual saliency of distracting inputs is high. This study augmented the classical forced-attention dichotic listening paradigm by adding an interaural intensity manipulation to investigate developmental differences in the interplay between perceptual saliency and attentional…
An fMRI Study of Neuronal Activation in Schizophrenia Patients with and without Previous Cannabis Use
Previous studies have mostly shown positive effects of cannabis use on cognition in patients with schizophrenia, which could reflect lower neurocognitive vulnerability. There are however no studies comparing whether such cognitive differences have neuronal correlates. Thus, the aim of the present study was to compare whether patients with previous cannabis use differ in brain activation from patients who has never used cannabis. The patients grou…
Adults with Attention-Deficit/Hyperactivity Disorder ? A Brain Magnetic Resonance Spectroscopy Study
The reduction of Glu/Cre in the left midfrontal region in the ADHD group may reflect a glutamatergic deficit in prefrontal neuronal circuitry in adults with ADHD, resulting in problems with cognitive control
Symmetry and asymmetry in the human brain
Structural and functional asymmetry in the human brain and nervous system is reviewed in a historical perspective, focusing on the pioneering work of Broca, Wernicke, Sperry, and Geschwind. Structural and functional asymmetry is exemplified from work done in our laboratory on auditory laterality using an empirical procedure called dichotic listening . This also involves different ways of validating the dichotic listening procedure against both in…
Bridging psychology and biology
Biological systems are particularly prone to variation, and the authors argue that such variation must be regarded as important data in its own right. The authors describe a method in which individual differences are studied within the framework of a general theory of the population as a whole and illustrate how this method can be used to address three types of issues: the nature of the mechanisms that give rise to a specific ability, such as men…

Lateral Asymmetries and Interhemispheric Transfer in Aging
Lonely traits and concomitant physiological processes
Nonaware classical conditioning to pictorial facial stimuli in a between-groups paradigm
Brain Asymmetry
Cardiovascular Conditioning and Anticipatory Nausea and Vomiting in Cancer Patients
Explanations of individual differences in susceptibility to learning of anticipatory nausea and/or vomiting (AN/V) in cancer patients have focused mainly on the patients who develop AN/V. On the basis of conditioning theory, however, one would expect that all patients who experience post-treatment nausea and/or vomiting (PN/V) should develop AN/V. Consistent with findings demonstrating that conditioned responses are more easily established in aut…
