Dopaminergic neurons innervating the striatum play a major role in drug addiction and movement. The functional role for dopamine neurons can be studied with DREADDs – designer receptors exclusively activated by designer drugs (in this case, CNO – clozapine N oxide). We utilized mice that selectively expressed an inhibitory DREADD receptor in dopaminergic neurons; when these mice were treated with CNO, we are able to silence presynaptic dopamine neurons. Also by testing a series of other control groups, we can test the specificity of this genetic system. By studying these mice in activity and reward consumption tests, we are able to find out more about how dopamine influences motivation and movement. Our goal is too see if presynaptic dopamine silencing has any effect on activity and motivation.
