Motor response inhibition in children with Tourette's disorder.
Tourette's disorder has long been regarded as a disorder of involuntary movement. Here the authors show that children with Tourette's disorder do not differ from healthy comparison subjects in stop-signal inhibition. These results suggest the importance of considering motor tics as voluntary rather than as involuntary.
