Reply to Keri,S. The magnocellular system and schizophrenia

Keri [Keri, S. (2008). The magnocellular pathway and schizophrenia. Vision Research, 48,1181-1182] raises concerns about the conclusion of our recent review [Skottun, B. C., & Skoyles, J. R. (2007a). Contrast sensitivity and magnocellular functioning in schizophrenia. Vision Research, 47, 2923-2933] that contrast sensitivity data provide little evidence for magnocellular deficits in schizophrenia. He also suggests other lines of evidence for such deficits. We respond that these concerns are unfounded, and that these other lines of evidence are weak. (C) 2008 Elsevier Ltd. All rights reserved.
