The parahippocampal gyrus is a cortical ridge in the medial temporal lobe, located superior to the tentorium. It is also known as the (discontinuous) occipitotemporal gyrus. The fusiform gyrus, and the FFA in particular, has consistently been found to respond atypically in ASD. The title of each work is an anagram of the title of the exhibition, 'Fusiform Gyrus', which is the name of a particular area of the brain: the lobe that . However, it is not widely known that the FG has a contentious history.

Because of the anatomical location variability of the FFA across subjects, this brain . (a) Examples of faces and objects used to localize selective regions in visual cortex.

These responses are most frequently found in or near the fusiform gyrus, but there is substantial variability in their anatomical location and response properties. The fusiform face area, or FFA, is a small region found on the inferior (bottom) surface of the temporal lobe. Contents 1 Structure 2 Function 3 History Here we use fMRI to show that the mid-fusiform gyrus responds with nearly the same level of selectivity to images of human bodies without faces, relative to tools and scenes. Orientation selective.

Location and structure At the neuroanatomical level, the fusiform gyrus is one of the largest structures inserted in the ventral temporal cortex.

Functional neuroimaging studies have revealed human brain regions, notably in the fusiform gyrus, that respond selectively to images of faces as opposed to other kinds of objects. This region, called the "Fusiform Face Area" (FFA) is located in a particular location in the temporal lobe called fusiform gyrus and is shown in this functional activation map. Brain imaging studies consistently find that this region of the temporal lobe becomes active when people look at faces.
