Stop That Action

Caption

Researchers from the University of Iowa studied how people stopped an action--first by measuring participants' brain waves and second by clocking the amount of time it took participants to stop an action when prompted to do so. The researchers found that an outside stimulus--the experimenters used a tone--led to a 15 percent improvement in the subjects' ability to physically stop an action. The finding offers promising insight in the brain's communication with the motor system, insight that could help clinicians treat patients with neurodegenerative disorders that involve motor-control deficiencies, from Parkinson's disease to aging.
