Ready, Set … GO! Scientists discover a brain circuit that triggers the execution of planned movement

The delayed execution of planned movement until a specific cue is essential for everyday behavior. For example, we wait until the traffic light turns green before turning. Now scientists have discovered how the brain uses an environmental cue, like a green light, to turn plans into action. This work offers insight into how brain activity is orchestrated to control complex behaviors. However, it also provides insight into the circuits that control cue-triggered movement, findings that may help optimize the treatment of movement disorders such as Parkinson’s Disease.
