Environmental cues, through their association with rewards, can acquire powerful control over motivation to spur and invigorate behavior. This process, while fundamental to survive, can go awry, leading to aberrant motivation that can underlie a variety of neuropsychiatric disorders, such as addiction. The central goals of the Saunders Laboratory are to understand 1) how the brain generates and controls motivation during reward seeking, 2) how these processes are altered in disease states, and 3) why some individuals, but not others, develop motivational diseases. We utilize in a variety of techniques for mapping, controlling, and measuring the activity of neural circuits, including optogenetics, pharmacology, calcium imaging, and immunohistochemistry and microscopy, in rodents. These methods are integrated with detailed assessment of behavior in conditioning paradigms of natural (i.e., food) reward and drug seeking, to identify how brain circuits represent and control different components of motivation.
