Both studies used the motor system as a window into brain function, and both support the hypothesis that inhibition is an important mechanism in cognition and behavior function, writes Jonathan W. Mink, MD, from the University of Rochester Medical Center in New York, in an accompanying editorial entitled "Faulty Brakes? Inhibitory Processes in Attention-Deficit/Hyperactivity Disorder."
