Bergen Stress and Sleep Group

The primary objective of this project is to establish translational research on early life stress with affective, behavioral outcome as well as genetic modulation, with a strong gender perspective.

Here you can read more about the project. 

The primary objective of this project is to establish translational research on the effects of simulated night shift work on waking performance, sleep, circadian rhythmicity, metabolic measures and molecular markers of brain function. The objective is also to investigate ways to counter these negative effects, particularly how light of different intensity and color quality impact on waking performance and brain function.
