The visual word form area (VWFA) is a functional region of the left fusiform gyrus and surrounding cortex (right-hand side being part of the fusiform face area) that is hypothesized to be involved in identifying words and letters from lower-level shape images, prior to association with phonology or semantics. produce a left-lateralized response within the fusiform gyrus (FG) at a characteristic location termed the visual word form area (VWFA).

The Talairach location for frontal cortex is the local maximum shown in Table 1 (36, 30, 16); for the fusiform location, it is also the Table 1 local maximum (46, 34, 20).

However, it is not widely known that the FG has a contentious history. These areas, as identified in functional magnetic resonance imaging (fMRI) studies, are of few square millimeters in size and are located outside of anatomically well-defined retinotopic visual areas (Halgren et al. It is also known as the (discontinuous) occipitotemporal gyrus.

Anteriorly it curves to form the uncus of the temporal lobe and posteriorly it appears continuous with the lingual gyrus .

The fusiform face area, or FFA, is a small region found on the inferior (bottom) surface of the temporal lobe. The fusiform gyrus is an important part of the brain, located in the Brodmann Area 37, between the lingual gyrus and the parahippocampal gyrus above it, and the inferior temporal gyrus below it, and is a part of the temporal and occipital lobe. It is located in the inferior temporal cortex (IT), in the fusiform gyrus ( Brodmann area 37 ). Where is the fusiform face area? More than 20 years ago, neuroscientist Nancy Kanwisher and others discovered that a small section of the brain located near the base of the skull responds much more strongly to faces than to other objects we see. The anterior border of the fusiform gyrus was noted to be towards the temporal pole.

An outstanding question is the extent to which ventral temporal cortex participates in pro-cessing dynamic, expressive aspects of faces, a function usually The fusiform gyrus was identified as follows: the medial margin was defined by the collateral and rhinal sulci, i.e., the boundary of the parahippocampal gyrus, and the lateral boundary was taken as the sulcus medial to the inferior temporal gyrus. We developed an experimental alphabet (FaceFont) comprising 35 .

Neuroimaging and electrophysiological studies across species have confirmed bilateral face-selective responses in the ventral temporal cortex (VTC) and prosopagnosia is reported in patients with lesions in the VTC including the fusiform gyrus (FG).

Nouchine Hadjikhani. The blood supply to the angular gyrus arises from the middle cerebral artery; a primary branch of the internal carotid artery. In the human brain, the mid-fusiform sulcus (MFS; sulcus sagittalis gyri fusiformis) divides the fusiform gyrus (FG) into lateral and medial partitions.Recent studies show that the MFS is identifiable in every hemisphere and is a landmark that identifies (a) cytoarchitectonic transitions among four areas of the FG, (b) functional transitions in many large-scale maps, and (c) the location of . It is also known as the (discontinuous) occipitotemporal gyrus. Areas in the right fusiform gyrus (fg) were significantly more active when subjects looked at faces than when they viewed an .

The standard profile of this functionally defined area in the mid-fusiform gyrus (mFG) is that it shows greater selectivity for words or alphabetic strings than other visual stimuli (Cohen et al., 2002; McCandliss, Cohen, & Dehaene, 2003), but the underlying . A and C present data in normal subjects, B and D in the dyslexic patients. A short summary of this paper.

The ability to recognize faces is so important in humans that the brain appears to have an area solely devoted to the task: the fusiform gyrus. Here we show robust face-selectivity in the lateral fusiform gyrus of congenitally blind participants during haptic exploration of 3D-printed stimuli, indicating that neither visual experience, nor fovea-biased input, nor visual expertise is necessary for face-selectivity to arise in its characteristic location. Edge detection. Color perception. Thus . The lateral and medial portions are separated by the shallow mid-fusiform sulcus. The fusiform face area is located in the midportion of the right fusiform gyrus and, as shown in the figure, D, lies immediately posterior to the damaged region.14 Thus, to relate the Frgoli syndrome to the lesion in the anterior fusiform gyrus, it may be assumed that there has been interference with specific past visual memories causing .
