In addition, anhedonia states are frequently reported in AN, potentially due to the physiological stress produced by the permanent starvation. We investigated the effect of fasting and satiety on mood and reaction times to monetary rewards in AN patients and healthy...

Involvement of nucleus accumbens dopamine D1 receptors in ethanol drinking, ethanol-induced conditioned place preference, and ethanol-induced psychomotor sensitization in mice

Bahi, Amine ; Dreyer, Jean-Luc

In: Psychopharmacology, 2012, p. -

Rationale: Dopamine D1 receptor (D1R) signaling has been associated to ethanol consumption and reward in laboratory animals.Objectives: Here, we hypothesize that this receptor, which is located within the nucleus accumbens (NAc) neurons, modulates alcohol reward mechanisms.Methods: To test this hypothesis, we measured alcohol consumption and ethanol-induced psychomotor sensitization and...
