A new study shows that overactivation of dopamine-producing neurons in the brain can trigger their degeneration, mirroring what happens in Parkinsons disease. Using a mouse model, researchers found that chronic activation disrupted daily activity patterns, damaged neuronal axons, and eventually killed cells in the substantia nigra.
