      Ravna, Aina Westrheim; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel, 2013)
      Hva skjer i hjernen når vi føler oss glade og optimistiske? Hvorfor virker penicillin mot bakterieinfeksjoner, mens paracet virker mot hodepine? Og hvordan i all verden kan antidepressiva påvirke humøret og dermed virke mot depresjon? Svaret er molekyler.
    • Vet brukerne hva de gjør? 

      Salamonsen, Anita (Chronicle; Kronikk, 2013-02-06)
      Nordmenns bruk av alternativ behandling er stadig under debatt blant leger, alternative behandlere og forskere, senest i forbindelse med NRK-programmet Folkeopplysningen. Det heteste temaet er om det finnes holdbar vitenskapelig dokumentasjon for at alternative behandlingsformer virker. Mange ser et paradoks i at alternativ behandling til tross for mangelfull dokumentasjon omsettes for milliardbeløp ...
