A paradoxical role for inhibition in initiation.
Rushworth MFS., Taylor PCJ.
Subliminal stimuli, of which subjects are unaware, affect movements made to subsequent visible cues. Sumner and colleagues in this issue of Neuron show that restricted supplementary motor and eye field lesions compromise voluntary control of action because they disrupt the normal unconscious and automatic inhibition of alternative movements partially activated by subliminal stimuli.
