In this study, we show that methylphenidate – a drug used to treat ADHD by increasing dopamine and norepinephrine – boosts the amount of time that the brain is engaged in both internal and external attention networks.

We previously found that systemic and central administration of GHSR antagonists reduced binge-like alcohol drinking, whereas a ghrelin vaccine did not. Thus, we hypothesized that central GHSR drives binge-like alcohol drinking independently of peripheral ghrelin.

We studied rats with hippocampus damage as they played a smell-based game. The game involved four contexts with different reward structures changing over time.

In this study. we investigated whether the deletion of the GHSR gene (GHSR-KO) in rats can prevent or attenuate weight gain caused by a high-fat diet.

Our study shows that activating a parallel VTA-originating glutamatergic pathway targeting the NAc shell can suppress psychostimulant-seeking behavior.

In this study, we used the delay-discounting task (DDT) to identify rats with different levels of impulsivity.
