Before revision: Neural basis of early selection for visual inputs may reside in the primary visual cortex, V1 , since more and more evidence has been accumulating for the V1 Saliency Hypothesis (V1SH) that the V1 creates a bottom-up saliency map to guide attention exogenously, and thus selection for visual inputs starts at V1 .
