Comparison of National Center for Biotechnology Information PubMed searches for studies studying primarily one or more retinotopic visual cortices (retrieved March 2015). Notes: For each search, the name of the visual area was required in the title and the word visual was required somewhere in the document (because the terms V1 and V2 are often used to refer to version numbers). This search is meant to be illustrative rather than exhaustive.
