A new study in mice suggests that a burst of activity in dopamine-producing neurons, just at the beginning of a movement only, as opposed to all the time, is all it takes for a movement to unfold correctly.

Our most important result is that we showed, for the first time, that the change in neural activity is necessary to promote movement. – Joaquim Alves da Silva, Neurobiology of Action Lab
