In 136 mice on FED3 tasks, males showed slightly higher win-stay in all three choice tasks, with higher accuracy in a deterministic bandit but not a probabilistic one.

This study identifies ventral pallidal GABAergic neurons as a key population controlling hedonic feeding and obesity in mice through optogenetic and ablation experiments.

This study shows that requiring mice to perform a simple action to access high-fat diet reduces intake and prevents obesity, suggesting that easy access promotes overeating.
