Frontal eye fields (FEFs) are responsible for the control of eye movements and the ability to shift visual attention. Synonyms for FEFs include the FEF cortex, the precentral sulcus, the frontal eye field region, and the supplementary eye field (SEF). The FEF cortex plays a vital role in coordinating and directing saccades, smooth pursuit, and vergence eye movements that are necessary for visual exploration and scanning. In comparison, the SEF is responsible for higher-level cognitive processes, such as the inhibition of reflexive saccades and the initiation of voluntary saccades. Understanding the various synonyms for FEFs can help to better appreciate the different functions within the brain that contribute to the visual system's optimal performance.
