Using a miniature electronic device implanted in the brain, scientists have tapped into the internal reward system of mice, prodding neurons to release dopamine, a chemical associated with pleasure. The researchers, at Washington University School of Medicine in St. Louis and the University of Illinois at Urbana-Champaign, developed tiny devices, containing light emitting diodes (LEDs) the size of individual neurons. The devices activate brain cells with light. The scientists report their...

Bird Brains Can Tell Us A Lot About Human Behavior
2013-02-28 05:30:56

redOrbit Staff & Wire Reports - Your Universe Online New research involving songbirds may help explain how the human brain is organized to govern skilled performance, a finding that could lead to new ways of understanding human speech production and other complex behaviors. The researchers found that whenever a bird sings, some of the neurons in its brain prepare to make the next sounds while others are synchronized with the current notes. This coordination of physical actions and...
