  • Response to J. D. Schall's E-Letter

    We thank J. D. Schall for his E-Letter in response to our Report, which demonstrated a common design of orientation maps in the striate cortex of species separated since the basal radiation of eutherian mammals ("Universality in the evolution of orientation columns in the visual cortex," M. Kaschube et al., 19 November 2011, p. 1113, published online 4 November 2010). Schall highlights the reality that despite the half...

  • An Alternative Hypothesis for Orientation Columns in the Visual Cortex

    In their Report "Universality in the evolution of orientation columns in the visual cortex" (19 November 2010, p. 1113, published online 4 November 2010), M. Kashube et al. demonstrate how a common principle of self-organization can explain the arrangement of orientation columns in species as diverse as the ferret, tree shrew, and galago and may also explain the absence of organized columns in rodents. Here, I highlig...
