Precise control of brain circuit alters mood

By combining super-fine electrodes and tiny amounts of a very specific drug, researchers have singled out a circuit in mouse brains and taken control of it to dial an animal’s mood up and down. Stress-susceptible animals that behaved as if they were depressed or anxious were restored to relatively normal behavior by tweaking the system, according to a study….
