===Extrastriate visual areas=== In extrastriate visual areas, cells can have very large receptive fields requiring very complex images to excite the cell. For example, in the [[inferotemporal cortex]], receptive fields cross the midline of visual space and require images such as radial gratings or hands. It is also believed that in the [[fusiform face area]], images of faces excite the cortex more than other images. This property was one of the earliest major results obtained through [[Functional magnetic resonance imaging|fMRI]] ([[Nancy Kanwisher|Kanwisher]], McDermott and Chun, 1997); the finding was confirmed later at the neuronal level ([[Doris Tsao|Tsao]], Freiwald, Tootell and [[Margaret Livingstone|Livingstone]], 2006). In a similar vein, people have looked for other category-specific areas and found evidence for regions representing views of places ([[parahippocampal place area]]) and the body ([[Extrastriate body area]]). However, more recent research has suggested that the fusiform face area is specialised not just for faces, but also for any discrete, within-category discrimination.<ref>{{cite journal|pmid = 23027970|doi=10.1073/pnas.1116333109|volume=109|issue=42|title=High-resolution imaging of expertise reveals reliable object selectivity in the fusiform face area related to perceptual performance|pmc=3479484|journal=Proc Natl Acad Sci U S A|pages=17063β8|last1 = McGugin|first1 = RW|last2 = Gatenby|first2 = JC|last3 = Gore|first3 = JC|last4 = Gauthier|first4 = I|year=2012 |bibcode=2012PNAS..10917063M|doi-access=free}}</ref>
