Cognitive function and brain plasticity in a rat model of shift work: role of daily rhythms, sleep and glucocorticoids
Marti, Andrea Rørvik; Pedersen, Torhild; Wisor, Jonathan P.; Mrdalj, Jelena; Holmelid, Øystein; Patil, Sudarshan; Meerlo, Peter; Bramham, Clive R.; Grønli, Janne (Journal article; Peer reviewed, 2020)Many occupations require operations during the night-time when the internal circadian clock promotes sleep, in many cases resulting in impairments in cognitive performance and brain functioning. Here, we use a rat model ... -
Early and Later Life Stress Alter Brain Activity and Sleep in Rats
Mrdalj, Jelena; Pallesen, Ståle; Milde, Anne Marita; Jellestad, Finn Konow; Murison, Robert; Ursin, Reidun; Bjorvatn, Bjørn; Grønli, Janne (Peer reviewed; Journal article, 2013-07-26)Exposure to early life stress may profoundly influence the developing brain in lasting ways. Neuropsychiatric disorders associated with early life adversity may involve neural changes reflected in EEG power as a measure ... -
The early life condition: Importance for sleep, circadian rhythmicity, behaviour and response to later life challenges
Mrdalj, Jelena (Doctoral thesis, 2014-12-09)Early life environment has a vast impact on development and adult functioning. Optimal brain development depends not only on genetic programming but also on specific external stimuli, where mother-infant relationships play ... -
No escaping the rat race: simulated night shift work alters the time-of-day variation in BMAL1 translational activity in the prefrontal cortex
Marti, Andrea Rørvik; Patil, Sudarshan; Mrdalj, Jelena; Meerlo, Peter; Skrede, Silje; Pallesen, Ståle; Pedersen, Torhild; Bramham, Clive R.; Grønli, Janne (Peer reviewed; Journal article, 2017-10-04)Millions of people worldwide work during the night, resulting in disturbed circadian rhythms and sleep loss. This may cause deficits in cognitive functions, impaired alertness and increased risk of errors and accidents. ... -
Shift in Food Intake and Changes in Metabolic Regulation and Gene Expression during Simulated Night-Shift Work: A Rat Model
Marti, Andrea Rørvik; Meerlo, Peter; Grønli, Janne; Hasselt, Sjoerd van; Mrdalj, Jelena; Pallesen, Ståle; Pedersen, Torhild; Henriksen, Tone Elise Gjøtterud; Skrede, Silje (Journal article; Peer reviewed, 2016)Night-shift work is linked to a shift in food intake toward the normal sleeping period, and to metabolic disturbance. We applied a rat model of night-shift work to assess the immediate effects of such a shift in food intake ... -
Sleep homeostasis and night work: a polysomnographic study of daytime sleep following three consecutive simulated night shifts
Pedersen, Torhild Thue; Sunde, Erlend; Wisor, Jonathan P.; Mrdalj, Jelena; Pallesen, Ståle; Grønli, Janne (Journal article; Peer reviewed, 2022)Purpose: Millions of people work at times that overlap with the habitual time for sleep. Consequently, sleep often occurs during the day. Daytime sleep is, however, characterized by reduced sleep duration. Despite preserved ...
