The fusiform gyrus is part of the temporal lobe in Brodmann Area 37. It is also known as the (discontinuous) occipitotemporal gyrus. [1] Other sources have the fusiform gyrus above the occipitotemporal gyrus and underneath the parahippocampal gyrus.[2]



There is still some dispute over the functionalities of this area, but there is relative consensus on the following:

  1. processing of color information
  2. face and body recognition (see Fusiform face area)
  3. word recognition
  4. number recognition [questionable: may only be as a result of a global response of any generic recognition tasks, further statistical evidence needed]
  5. within-category identification

Some researchers think that the fusiform gyrus may be related to the disorder known as prosopagnosia, or face blindness. Research has also shown that the fusiform face area, the area within the fusiform gyrus, is heavily involved in face perception but only to any generic within-category identification which is shown to be one of the functions of the fusiform gyrus.[3] Fusiform gyrus has also been involved in the perception of emotions in facial stimuli.[4]

Increased neurophysiological activity in the fusiform face area may produce hallucinations of faces, whether realistic or cartoonesque, as seen in Charles Bonnet syndrome, hypnagogic hallucinations, peduncular hallucinations, or drug-induced hallucinations.[5]

Recent research has seen activation of the fusiform gyrus during subjective grapheme-color perception in people with synaesthesia.[6]
