New role for insulin: Studies tie the hormone to brain's 'pleasure' center Insulin, the hormone essential to all mammals for controlling blood sugar levels and a feeling of being full after eating, plays a much stronger role than previously known in regulating release of dopamine, a neurotransmitter that helps control the brain's reward and pleasure centers
Discovery could lead to better recovery after stroke Researchers have identified a molecule that, after a stroke, signals brain tissue to form new connections to compensate for the damage and initiate repairs to the brain
