Echoes from Intrinsic Connectivity Networks in the Subcortex
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-27)Decades of research have greatly improved our understanding of intrinsic human brain organization in terms of functional networks and the transmodal hubs within the cortex at which they converge. However, substrates of multinetwork integration in the human subcortex are relatively uncharted. Here, we leveraged recent advances in subcortical atlasing and ultra-high field (7 T) imaging optimized for ... -
Sexual Incentive Motivation
(Chapter; Bokkapittel, 2023-05-17)Motivation can be described as the processes that activate, direct, and determine the persistence of goal-directed behavior. A certain level of sexual motivation is required to activate approach behavior which could potentially lead to copulation and reproduction. Here, we discuss the use of the sexual incentive motivation test to assess the magnitude of sexual motivation in rodents in response to ... -
Impact of active placebo controls on estimated drug effects in randomised trials: a systematic review of trials with both active placebo and standard placebo
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-06)Background - An estimated 60% of pharmacological randomised trials use placebo control interventions to blind (i.e. mask) participants. However, standard placebos do not control for perceptible non‐therapeutic effects (i.e. side effects) of the experimental drug, which may unblind participants. Trials rarely use active placebo controls, which contain pharmacological compounds designed to mimic the ... -
Aktigrafi som supplerende mål på fysisk funksjon hos personer med CFS/ME sett i sammenheng med fatigue, psykisk helse og livskvalitet
(Master thesis; Mastergradsoppgave, 2019-05-09)Det er flere utfordringer knyttet til selvrapporterte mål på symptomer og funksjonsnivå ved kronisk utmattelsessyndrom. Et objektivt mål som kan supplere slike subjektive vurderinger av tilstanden er etterspurt for bedre å kunne fange opp endring etter tiltak.

The elusive concept of sexual motivation: can it be anchored in the nervous system?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-17)Sexual motivation is an abstract concept referring to the mechanisms determining the responsivity to sexually relevant stimuli. This responsivity determines the likelihood of producing a sexual response and the intensity of that response. Both responsivity to stimuli and the likelihood of making a response as well as the intensity of response are characteristics of an individual. Therefore, we need ... -

Too different to be equal: Lack of public respect is associated with reduced self‐respect for stigmatized individuals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-25)Individuals with physical and mental disabilities can be stigmatized and perceived in terms of their disabilities in the public domain. This is less pervasive in the private domain, because of the presence of individuating information. We argue that disabilities decrease individuals’ everyday opportunities to receive basic equality-based respect experiences in the public domain and thus makes it ... -
Ubevisst aktivering av betinget smerteresponser og spatiale frekvenser
(Mastergradsoppgave; Master thesis, 2021-12-14)Bakgrunn: Kroniske smerte har de siste årene blitt mer utbredt, men kunnskapen om kroniske smerter er fortsatt lav. Sentralnervesystemet (SNS) sees på som viktig i forhold til forståelse av slike smerter. SNS bruker endogen smertemodulering for å redusere eller forsterke smerten et individ opplever. Nyere forskning viser at endogen smertemodulering kan påvirkes av ubevisste mekanismer, men hvordan ... -
