Unlike preprints, which are uploaded before an article is actually published in a journal, there are various ways of making sure the final version published in the journal itself (the published version) is Open Access.
Green Open Access
Green Open Access  refers to making a relatively final version of the publication Open Access either at the time it is published in a journal or sometime after. The best way to practice Green Open Access is by uploading your accepted manuscript to an openly accessible repository. The version you upload to such a repository is the one with final content, but not all of the final journal formatting (also known as the “accepted version” or “accepted manuscript”). Depending on the journal where the article was published, you may only be allowed to share in this way after a delay (known as an “embargo period”). McGill University offers such an institutional digital repository at eScholarship@McGill . Submit your work to eScholarship using this online form.
Bronze/Hybrid Open Access
Bronze/Hybrid Open Access  means publishing an Open Access manuscript in a journal where articles are not openly accessible by default, usually requiring an Article Processing Charge (APC). Journals providing Bronze/Hybrid Open Access publishing have a mix of Closed and Open Access articles.
A key difference between Bronze and Hybrid models is that while Hybrid journals apply an open license to articles, allowing for reuse, Bronze journals do not have a clear open license and are therefore not openly reusable; they can only be read on the journal’s website. This is considered a less open approach because it prevents reuse and takes away rights from authors.
Gold Open Access
Gold Open Access  means publishing in a journal where all articles are Open Access. For journals that publish neuroscience findings, these journals often charge an APC, which generally ranges from around $500 to $10,000 USD. Visiting the Sherpa Romeo and the DOAJ websites  will help you identify the quality/cost ratio best for you. McGill also offers some APC discounts, check the [information](LINK) for a few of the top Used Neuro Journals.
Other Open Access journals, however, use alternative business models that allow them to provide “free to read, free to publish” Open Access (sometimes known as Diamond or Platinum Open Access) .
