Abstract The stimulus-driven contribution to the allocation of attention is bottom-up attention. Investigating its neural mechanisms leads to a better understanding of how the brain creates consciousness. Although bottom-up selection is typically quick and potent, there are controversies concerning the brain regions involved. Two models with their respective evidence about bottom-up attention over the past decades were reviewed: the saliency-based attention and primary visual cortex (V1) saliency map models. Finally, we discussed issues for future studies.
