Research Abstract |
Diet-induced obese mice exhibit higher preference for fat in a diet. This behavior change in mice is associated with decrease in the excitation of GABA neurons and decrease in D2 receptor-mediated inhibition of dopamine neurons in the reward-related brain area. We suggest that the acceleration of dopaminergic function in the brain reward system contributes to high fat preference in diet-induced obesity.
