The frontal eye filed (FEF) is a relatively small frontal region that has been intensely studied. It received multiple definitions that help to locate it with some discrepancies between non-human primates and humans. The goal of this review is to provide an inter-species comparison of the location, extent, and boundaries of the FEF through the multiple anatomical and functional methodologies that has been used for its description as an oculomotor-associated area. We therefore propose a new orientation for using white matter fibers co-localizations between frontal structures to study their evolution and clarify the FEF homologies in primates.
