The human FFA was first described by Justine Sergent in 1992 and more recently by Nancy Kanwisher in 1997 who proposed that the existence of the FFA is evidence for domain specificity in the visual system.
More recently, it has been suggested that the FFA is a processing center for more than just faces. Some groups, including Isabel Gauthier and others, maintain that the FFA is an area for recognizing fine distinctions between well-known objects. Gauthier tested both car and bird experts, and found some activation in the FFA when car experts were identifying cars and when bird experts were identifying birds.
A recent paper by Kalanit Grill-Spector also suggests that processing in the FFA is not exclusive to faces. Although an erratum was later published which brought to light errors in this paper, the information presented nonetheless suggests that those in the field of neuroscience need to rethink their interpretations of the FFA.
