Brain illnesses that affect cognition and emotion are the most prevalent and the most devastating of human disorders. Whether it is a chronic disease such as schizophrenia or transient bouts of anxiety and panic attacks, they influence every aspect of an individual's life and produce enduring personal anguish and hardship to family. New treatments for these conditions are contingent upon research breakthroughs that explain the neuronal processes that support cognition and emotion. By increasing our basic understanding of how these processes work, we can identify genetic or environmental causes that disrupt them. It is then that we can find cures or prevention strategies for these disorders. We use a systems neuroscience approach to study "dynamic" brain mechanisms that maintain cognitive and emotional functions in key brain regions that are implicated in illnesses such as schizophrenia, ADHD, anxiety, and addictive disorders. Our primary focus is on prefrontal cortex subregions and dopamine neurons in the midbrain. New directions include characterization of these neuronal systems during adolescence. The onset of symptoms for most psychiatric disorders is during adolescence; therefore, understanding what goes awry in this developmental period is critical for defining the neuronal basis of the disease process and designing strategies that prevent the onset of symptoms.
