Dopamine is your brain's way of saying 'job well done'.
Strangely, the loss of these nerve cells doesn't necessarily result in a loss of rewarding feelings following a successful or joyful task. So it's been unclear until now if the neurons that respond to the hormone generally have more than one job, or if different cells are each responsible for their own function.
Though Dombeck's lab had uncovered dopamine neurons that governed movement previously, they assumed this handful of cells were simply moonlighting in motion, with reward response still their primary occupation. They found roughly 30 percent of the dopamine-reactive neurons lit up whenever the mice moved, leaving responses to aversive or rewarding behaviors to the remaining nerve cells.fellow neurobiologist and co-lead author Rajeshwar Awatramani.
