Sweet tooth? Flies have it too: New study shows how they know what to eat and when to stop

The researchers filmed hungry flies drinking a drop of sugar solution (blue circles in the top panel) and simultaneously monitored the activity of their IN1 cells before, during, and after the drink was consumed (bottom panels). The cells remained active for several minutes after the solution had been swallowed. Credit: Laboratory of Neurogenetics and Behavior […]
