Abstract
The light at the zebra crossing has just switched to green, and you are about to step out onto the road when a cyclist comes racing past. Clearly, sometimes it is necessary to cancel an action that you intended to make. Such reactive action inhibition has been proposed to involve a rapid ‘stop’ process that races to interrupt the ‘go’ process. In a new study, Berke and colleagues provide evidence that stopping literally involves a race between distinct pathways through the basal ganglia that converge on the same neurons (Author/publisher)
