Reflexive responses are often in direct competition with voluntary control. We test two opposing explanations for how this competition is resolved with respect to eye movements. One states that the quickest activation wins. The other states that the strongest activation wins. We show that an eye movement is executed according to the strongest activation, with the competition being staged at a common subcortical site. (C) 2004 Elsevier B.V. All rights reserved.
