In “Selective and Divided Attention during Visual Discriminations of Shape, Color, and Speed: Functional Anatomy by Positron Emission Tomography,” by Maurizio Corbetta et al. (The Journal of Neuroscience 11:2383–2402, August 1991), in the discussion section “Attention to speed” on page 2396, the authors incorrectly listed Zeki et al. in the citations of a sentence that referred to the work of Miezin and colleagues. The paper by Zeki et al. (1991) reports separate work, in which a similar activation occurs under very similar stimulation conditions.
