Cocaine, morphine commandeer neurons normally activated by food, water in mice

Confirming a long-held hypothesis, repeated exposure to the drugs alters neurons in the nucleus accumbens, the brain’s reward center, and curbs an animal’s urge for sustenance.

Drafting a ‘dysfunctome’: Faulty connections to subthalamic nucleus characterize disparate brain disorders

Different circuits between the millimeters-wide structure and the cortex go awry in Tourette syndrome, obsessive-compulsive disorder, dystonia and Parkinson’s disease, a new study of human brain scans suggests.
