This study aims to investigate the underlying neurobiological mechanisms that regulate natural reward seeking behaviors, specifically in the context of sexual behavior and sucrose self-administration. The role of CaMKIIa+neurons in the bed nucleus of the stria terminalis (BNST) was explored using chemogenetic silencing and -stimulation. Additionally, the study examined how these effects ...

The aim of this study was to investigate whether transcranial Direct Current Stimulation (tDCS) could improve verbal memory functions in healthy old and younger participants. We hypothesized that active tDCS led to significantly improved memory function, compared to placebo tDCS. Forty healthy participants (20 old and 20 younger participants) were included in the study. We applied a novel stimulation ...

<p><i>Rationale:</i> The place of case reports in the medical literature has been much debated in recent years. This study was undertaken to gain knowledge about the publication practice of case reports and case series from a major university hospital. <p><i>Method:</i> We decided to conduct a retrospective, bibliographic, descriptive study of published case reports and case series from a university ...

<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. ...

Multiple cognitive domains, including learning, memory, and psychomotor speed, show significant reductions with age. Likewise, several cerebrospinal fluid (CSF) neurodegenerative biomarkers, including total tau (t-tau, a marker of neuronal body injury) and neurofilament light chain (NfL, a marker of axonal injury) show age-related increases in normal aging. In the current study, we aimed to investigate ...

<i>Background</i>: Previous research shows that physical activity has a protective effect on mental distress in adults, but the relationship is less researched and seems more ambiguous for adolescents. Studies in this field have typically been cross-sectional by design and based on self-reported physical activity measures, which are known to be vulnerable to response bias. The aim of this study ...

The aim of this study is to investigate the association between childhood sensorineural hearing loss (CSNHL) and divorce in a large, Norwegian cohort. Data from the School Hearing Investigation in Nord-Trøndelag (SHINT), Norway, are combined with registry data on marital status from Statistics Norway and matched controls from the Nord-Trøndelag Health Study (HUNT). The sample includes a total of ...

COVID-19 triggered social restrictions worldwide including the shutdown of schools. Whereas research has documented the negative effects on parents’ well-being, less is known about children’s well-being during the pandemic. We investigated the well-being, emotions, and COVID-19-related attitudes of 87 Norwegian elementary children (42 boys, 45 girls; M_age = 9.66 years, SD = 1.77) and their ...

Few consistent predictive factors for eating disorder have been identified across studies. In the current five year prospective study, the objective was to examine whether (1) personality disorder and child sexual abuse predict the course of severity of eating disorder symptoms after inpatient treatment and (2) how the predictors interact. A total of 74 patients with long standing eating disorder ...
