It has been brought to our attention after publication that a prior study by Jancke and colleagues (Onat et al., 2011) demonstrated retinotopic-scale luminance representation of low spatial frequency drifting gratings in anesthetized cat areas 17 and 18. Such a representation is likely to be related to the luminance-retinotopic responses to flashed gratings reported in the current study. We therefore apologize for not citing this work in the original publication of our manuscript. It has since been cited in our paper online.
