Unraveling the Neural Roots of Post-Meal Cravings

UCLA psychologists have identified “overactive food-seeking neurons” as potential culprits behind post-meal snack cravings rather than an excessive appetite. Published in Nature Communications, the study unveils a brain circuit in mice, prompting relentless food pursuit irrespective of hunger. These neurons, nestled in the periaqueductal gray region, drive mice to fervently seek fatty, pleasurable foods. Contrarily, activating the vgat periaqueductal gray cells deters food-seeking behaviors. Human parallels suggest implications for eating disorders. Notably, compulsive eating induced by these cells aligns with humans’ potential heightened reward response to food. These findings present a promising avenue for understanding and addressing eating disorders.
