Before revision: Neural basis of early selection for visual inputs may reside in the primary visual cortex, also called V1, the first stage in the neocortex along the visual pathway for visual input information from the retina --- evidence has been accumulating in support of the V1 Saliency Hypothesis (V1SH) proposed in the late 1990s that the V1 creates a bottom-up saliency map to guide attention exogenously, and thus selection for visual inputs starts at V1 .
