A colorful snapshot of how your brain connects mem A colorful snapshot of how your brain connects memories to appetite 🧠💚 In this image, the bright green cells are part of a newly identified brain circuit that links past experiences, like where you’ve enjoyed a meal before, to how much you want to eat in the present. In a new study, @massgeneralbrigham researchers found that these cells act as messengers between the brain’s memory center and the region that controls appetite, helping translate context into cravings or restraint. When this pathway was disrupted in preclinical models, they were less able to use past experiences to guide their eating and showed increased appetite in unfamiliar settings. The findings suggest that when this memory-to-appetite circuit isn’t working properly, it could contribute to disordered eating and obesity, and may even help explain how some widely used weight-loss medications affect the brain.
