Spontaneous brain activity and EEG microstates. A novel EEG/fMRI analysis approach to explore resting-state networks.
2009
The brain is active even in the absence of explicit input or output as demonstrated from electrophysiological as well as imaging studies. Using a combined approach we measured spontaneous fluctuations in the blood oxygen level dependent (BOLD) signal along with electroencephalography (EEG) in eleven healthy subjects during relaxed wakefulness (eyes closed). In contrast to other studies which used the EEG frequency information to guide the functional MRI (fMRI) analysis, we opted for transient EEG events, which identify and quantify brain electric microstates as time epochs with quasi-stable field topography. We then used this microstate information as regressors for the BOLD fluctuations. S…
Task-induced deactivation in diverse brain systems correlates with interindividual differences in distinct autonomic indices
2018
AbstractNeuroimaging research has shown that different cognitive tasks induce relatively specific activation patterns, as well as less task-specific deactivation patterns. Here we examined whether individual differences in Autonomic Nervous System (ANS) activity during task performance correlate with the magnitude of task-induced deactivation. In an fMRI study, participants performed a continuous mental arithmetic task in a task/rest block design, while undergoing combined fMRI and heart / respiration rate acquisitions using photoplethysmograph and respiration belt. As expected, task performance increased heart-rate and reduced the RMSSD, a cardiac index related to vagal tone. Across partic…
Unemployment transitions and self-rated health in Europe: A longitudinal analysis of EU-SILC from 2008 to 2011
2015
- The Great Recession of 2008 has led to elevated unemployment in Europe and thereby revitalised the question of causal health effects of unemployment. This article applies fixed effects regression models to longitudinal panel data drawn from the European Union Statistics on Income and Living Conditions for 28 European countries from 2008 to 2011, in order to investigate changes in self-rated health around the event of becoming unemployed. The results show that the correlation between unemployment and health is partly due to a decrease in self-rated health as people enter unemployment. Such health changes vary by country of domicile, and by individual age; older workers have a steeper decli…
Clinical Application Research through reflection, interpretation and new understanding - a hermeneutic design
2018
The implementation of theoretical knowledge in clinical practice and the implementation of good clinical practice into theory have been of interest in caring science for the last 30 years. The aim of this article was to elaborate and discuss a methodology named clinical application research. The method is grounded in a hermeneutical design inspired by Gadamer's philosophy. The methodology, clinical application research, has been used in a research project A life in dignity and experiences from the researchers forms the bases for the elaboration and discussion. The project was performed in collaboration with residents, family caregivers and healthcare providers at six nursing homes in Scandi…
The facilitative effect of gestures on the neural processing of semantic complexity in a continuous narrative
2019
© 2019 Elsevier Inc. Gestures are elemental components of social communication and aid comprehension of verbal messages; however, little is known about the potential role of gestures in facilitating processing of semantic complexity in an ecologically valid setting. The goal of this study was to investigate whether cognitive load, as indexed by semantic complexity, is modulated by the presentation of gestures accompanying speech. Twenty healthy participants watched 16 video clips of a short narrative while instructed to carefully listen to and watch the narrator while functional magnetic resonance imaging (fMRI) data were acquired. The videos contained passages with and without various co-s…
Patients’ experiences of continued treatment with extended-release naltrexone: a Norwegian qualitative study
2022
Abstract Background The opioid antagonist extended-release naltrexone (XR-NTX) in the treatment of opioid use disorder (OUD) is effective in terms of safety, abstinence from opioid use and retention in treatment. However, it is unclear how patients experience and adjust to losing the possibility of achieving an opioid effect. This qualitative study is the first to explore how people with opioid dependence experience XR-NTX treatment, focusing on the process of treatment over time. Methods Using a purposive sampling strategy, semi-structured interviews were undertaken with 19 persons with opioid use disorder (15 men, four women, 22–55 years of age) participating in a clinical trial of XR-NTX…
Diet and Neurodevelopmental Score in a Sample of One-Year-Old Children-A Cross-Sectional Study

Environmental factors in the first years of life are crucial for a child&rsquo
Associations between infant and maternal characteristics measured at child age 5 months and maternal feeding styles and practices up to child age two…
2022
Facilitating positive feeding practices from infancy may be an important strategy to prevent childhood overweight and obesity. Since the feeding situation early in life constitutes a bidirectional relationship, it is important to understand the impact of both maternal and infant characteristics on maternal feeding practices to intervene in a customized and tailored way. Few studies have concurrently examined associations between maternal and infant characteristics in relation to early maternal feeding practices. The aim of the present study was to explore potential associations between infant and maternal characteristics measured at child age five months, and maternal feeding styles and pra…
Changes in self-rated health and quality of life among Syrian refugees migrating to Norway: a prospective longitudinal study
2020
Abstract Background Forced migrants can be exposed to various stressors that can impact their health and wellbeing. How the different stages in the migration process impacts health is however poorly explored. The aim of this study was to examine changes in self-rated health (SRH) and quality of life (QoL) among a cohort of adult Syrian refugees before and after resettlement in Norway. Method We used a prospective longitudinal study design with two assessment points to examine changes in health among adult Syrian resettlement refugees in Lebanon accepted for resettlement in Norway. We gathered baseline data in 2017/2018 in Lebanon and subsequently at follow-up one year after arrival. The mai…
Teachers’ experiences of adolescents’ pain in everyday life: a qualitative study
2015
Objectives More adolescents report pain now than previously. In Norway, episodic pain problems have been reported by 60% of children and adolescents aged 8–18 years, with 21% reporting duration of pain of more than 3 months. Since adolescents spend much time at school, the attitude and behaviour of teachers play important roles regarding the experience of pain felt by adolescents in everyday life. Yet research on how teachers perceive the pain experienced by adolescents in a school setting is limited. We therefore seek to gain insight to teachers’ classroom experiences with (1) adolescent's self-reported pain symptoms; (2) adolescents management of their pain and (3) how to help adolescents…
