Check out how the AgRP activity (green) is correlated with distance to food (magenta)!

Remarkably, this proximity-related signal persists during memory recall even when no food is available. Together, our findings suggest that AgRP neurons integrate internal hunger state with learned spatial information during foraging.

Happy to share our preprint! We show that hypothalamic hunger-promoting AgRP neurons reflect proximity to food across different mazes in hungry mice. After mice discover food, AgRP activity decreases as they approach the food and increases as they move away.
