Effects of gonadectomy and dihydrotestosterone on neuronal plasticity in motivation and reward related brain regions in the male rat
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-06)Gonadal hormones affect neuronal morphology to ultimately regulate behaviour. In female rats, oestradiol mediates spine plasticity in hypothalamic and limbic brain structures, contributing to long‐lasting effects on motivated behaviour. Parallel effects of androgens in male rats have not been extensively studied. Here, we investigated the effect of both castration and androgen replacement on spine ... -

Model Gender Interacts With Expressed Emotion to Enhance Startle: Angry Male and Happy Female Faces Produce the Greatest Potentiation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-09)Several studies have implied gender differences in startle reaction to emotional facial expressions. However, few studies have been designed to investigate the difference between responding to emotional female vs. male faces, nor gender differences in responses. The present experiment investigated startle EMG responses to a startle probe while viewing pictures of neutral, happy, angry, fearful, and ... -

The Cafeteria Diet: a standardized protocol and its effects on behavior
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-10)Obesity is a major health risk, with junk food consumption playing a central role in weight gain, because of its high palatability and high-energy nutrients. The Cafeteria (CAF) diet model for animal experiments consists of the same tasty but unhealthy food products that people eat (e.g. hot dogs and muffins), and considers variety, novelty and secondary food features, such as smell and texture. ... -
Probing the neural signature of mind wandering with simultaneous fMRI-EEG and pupillometry
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-01)Mind wandering reflects the shift in attentional focus from task-related cognition driven by external stimuli toward self-generated and internally-oriented thought processes. Although such task-unrelated thoughts (TUTs) are pervasive and detrimental to task performance, their underlying neural mechanisms are only modestly understood. To investigate TUTs with high spatial and temporal precision, we ... -
Amyloid plaques and symptoms of depression links to medical help-seeking due to subjective cognitive decline
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-02)<i>Background:</i> Subjective cognitive decline (SCD) is associated with an increased risk of Alzheimer’s disease (AD).

Cerebral cortical thickness and surface area in adolescent anorexia nervosa: Separate and joint analyses with a permutation-based nonparametric method
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-17)<i>Objective</i> - Reduction in cerebral volume is often found in underweight patients with anorexia nervosa (AN), but few studies have investigated other morphological measures. Cortical thickness (CTh) and surface area (CSA), often used to produce the measure of cortical volume, are developmentally distinct measures that may be differentially affected in AN, particularly in the developing brain. ... -
Does she comfort the victim whilst he punishes the perpetrator? No gender differences in anonymous economic games across 11 nations.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-26)Social role theory posits that occupational gender roles give rise to gender differences in behavior, such that men and women engage in qualitatively different prosocial behaviors. Therefore, we expected that women who observed an unfair situation (involving a victim and a perpetrator) would respond by demonstrating communal prosocial behavior (by compensating the victim), whereas men would respond ... -
