What insulin (and leptin) say to the brain

Researchers report new evidence to explain just what message insulin delivers to our brains. The study also shows that leptin, an appetite suppressant hormone produced in fat tissue, delivers at least a partially overlapping message to the neurons that critically control energy balance. It's only when both receptors go missing from those so-called POMC neurons in mice that the animals show signs of systemic insulin resistance as their blood sugar levels rise.
