Where is lateral occipitotemporal gyrus?
Daniel Lopez The Fusiform gyrus - Wikipedia
What are Occipitotemporal regions?
They have proposed the notion of a retinotopically organized occipitotemporal area (Malach et al., 2002), which runs from the posterior fusiform gyrus to the collateral sulcus. Within this region, specific areas respond maximally to different object categories (animals, objects, houses, faces, and words).
Where is the Occipitotemporal sulcus?
The occipitotemporal sulcus, also known as the lateral occipitotemporal sulcus, runs anteroposteriorly on the inferior surface of the temporal lobe, separating the inferior temporal gyrus laterally from the fusiform gyrus medially.
What is fusiform gyrus responsible for?
The right fusiform gyrus is responsible for facial recognition, and its activation is reduced in response to happy faces in comparison with HCs. Modulation of activity in the facial processing area has been suggested to contribute to changes in the salience of such emotional stimuli.
What is lateral Occipitotemporal gyrus?
The fusiform gyrus, also known as the lateral occipitotemporal gyrus is a structure that lies on the basal surface of the temporal and occipital lobes. It forms part of Brodmann area 37, along with the inferior and middle temporal gyri.

21 related questions foundIs the dentate gyrus part of the hippocampus?
The dentate gyrus is found in the temporal lobe, adjacent to the hippocampus. There is not a consensus, however, on how to anatomically demarcate the hippocampus and its neighboring regions, and some sources consider the dentate gyrus to be part of the hippocampus.
What is the Occipitotemporal cortex?
Human lateral occipitotemporal cortex (LOTC) supports action perception and knowledge. ... We propose that patterns of activity in LOTC form representational spaces, the dimensions of which capture perceptual, semantic, and motor knowledge of how actions change the state of the world.
Where is the Supramarginal gyrus located?
The supramarginal gyrus (plural: supramarginal gyri) is a portion of the parietal lobe of the brain. It is one of the two parts of the inferior parietal lobule, the other being the angular gyrus. It plays a role in phonological processing (i.e. of spoken and written language) and emotional responses.
What is the gyrus rectus?
The gyrus rectus, or straight gyrus, is located at the medial most margin of the inferior surface of frontal lobe 1,2. Its function is unclear but it may be involved in higher cognitive function (e.g. personality) 3.
Which gyrus lies posterior of the inferior frontal gyrus?
Considering its size, the frontal lobe has relatively few constant sulci and gyri (Fig. 1a). The most posterior gyrus is the precentral gyrus, which lies between the Rolandic and the precentral sulci and contains the motor cortex and part of the premotor cortex.
Where is the superior temporal gyrus?
Gross anatomy
The superior temporal gyrus is situated at the topmost aspect of the temporal lobe, lying inferior to the lateral sulcus and superior to the superior temporal sulcus.
What is the function of the superior temporal gyrus?
The superior temporal gyrus (STG) is implicated in the processing of eye movements, as well as in the visual analysis of social information conveyed by gaze and body movement (Allison et al., 2000; Hoffman and Haxby, 2000; Pelphrey et al., 2005; Puce et al., 1998).
Where is the right fusiform gyrus?
The fusiform gyrus is located on the basal surface of the occipital and temporal lobe. The fusiform gyrus is bounded medially by the collateral sulcus, which separates it from the parahippocampal gyrus.
Where is the visual area?
The primary visual cortex is found in the occipital lobe in both cerebral hemispheres. It surrounds and extends into a deep sulcus called the calcarine sulcus.
Where is the Broca's area located?
New research shows that Broca's area, located in the frontal cortex and shown here in color, plans the process of speech by interacting with the temporal cortex, where sensory information is processed, and the motor cortex, which controls movements of the mouth.
What connects Broca's and Wernicke's area?
Broca's area and Wernicke's area are connected by a large bundle of nerve fibres called the arcuate fasciculus.
What is the Broca's area function?
Broca's area is also known as the motor speech area. It is near the motor cortex and utilized in speech production, located in the inferior frontal gyrus. This area regulates breathing patterns while speaking and vocalizations required for normal speech.
When was the fusiform gyrus discovered?
The fusiform gyrus is first labeled in 1854 and the mid-fusiform sulcus in 1896.
Where is the dentate gyrus in the hippocampus?
The dentate gyrus is found in the temporal lobe, adjacent to the hippocampus. There is not a consensus, however, on how to anatomically demarcate the hippocampus and its neighboring regions, and some sources consider the dentate gyrus to be part of the hippocampus.
Is the dentate gyrus part of the limbic system?
The limbic system includes the hippocampal formation, amygdala, septal nuclei, cingulate cortex, entorhinal cortex, perirhinal cortex, and parahippocampal cortex. ... The term hippocampal formation typically refers to the dentate gyrus, the hippocampus proper (i.e., cornu ammonis), and the subicular cortex.
Where is the fusiform face area located?
Approximate location of the fusiform face area, inferior view (looking at the bottom of the brain). The fusiform face area, or FFA, is a small region found on the inferior (bottom) surface of the temporal lobe. It is located in a gyrus called the fusiform gyrus.
What does angular gyrus do?
The angular gyrus (AG) is a hub of several networks that are involved in various functions, including attention, self-processing, semantic information processing, emotion regulation, and mentalizing. Since these functions are required in music performance, it is likely that the AG plays a role in music performance.
