Dynamic and Diverse Roles of Dopamine

Neural circuits are dynamically regulated by a diverse class of secretedmolecules known as neuromodulators, amongwhich is dopamine, amolecule linked to disorders such as Parkinson’s disease and schizophrenia and to reward-driven learning. This Select highlights several recently published papers that elucidate how dopamine neurons regulate circuits involved in depression-related behaviors, learning related to nutritional reward, and susceptibility to addiction.
