Skiftarbeid og spesielt nattskift er assosiert med ulike helseplager, der søvnproblemer er mest uttalt. For lite søvn påvirker vår våkenhetsfunksjon, og evne til kognitiv ytelse og oppmerksomhet vil kunne bli redusert. Mitt PhD-prosjekt er translasjonelt og involverer simulert nattarbeid hos både rotter og mennesker. Jeg ønsker å undersøke hvordan nattarbeid påvirker våkenhetsfunksjon og kognitiv ytelse under nattskiftet, og søvnen etter arbeid. Jeg ønsker også se på hvordan ulike lysbetingelser under simulerte nattskift kan påvirke hjernens prosesseringsevne og søvnen etter nattskiftet.
