The '''middle temporal visual area''' ('''MT''' or '''V5''') is a region of extrastriate visual cortex. In several species of both [[New World monkey]]s and [[Old World monkey]]s the MT area contains a high concentration of direction-selective neurons.<ref name="BornBradley" /> The MT in primates is thought to play a major role in the [[motion perception|perception of motion]], the integration of local motion signals into global percepts, and the guidance of some [[Eye movement (sensory)|eye movements]].<ref name="BornBradley">{{cite journal | vauthors = Born RT, Bradley DC | title = Structure and function of visual area MT | journal = Annual Review of Neuroscience | volume = 28 | pages = 157–189 | year = 2005 | pmid = 16022593 | doi = 10.1146/annurev.neuro.26.041002.131052 }}</ref>
