What is superior temporal sulcus?
The superior temporal sulcus (STS) is the chameleon of the human brain. Several research areas claim the STS as the host brain region for their particular behavior of interest. Some see it as one of the core structures for theory of mind. For others, it is the main region for audiovisual integration.
What is the role of the superior temporal gyrus?
The superior temporal gyrus (STG) is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition.
What is the function of the fusiform gyrus?
The fusiform gyrus is a large region in the inferior temporal cortex that plays important roles in object and face recognition, and recognition of facial expressions is located in the fusiform face area (FFA), which is activated in imaging studies when parts of faces or pictures of facial expressions are presented to …
What is the superior border of the superior temporal gyrus?
The superior temporal gyrus is bounded by: the lateral sulcus above; the superior temporal sulcus (not always present or visible) below; an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly.
What is inferior temporal gyrus?
a ridge (gyrus) that extends along the lower surface of the temporal lobe of the brain, bounded above by the middle temporal sulcus. It has a role in language, semantic memory, visual processing, and sensory integration.
What happens if the superior temporal gyrus is damaged?
4.4 Damage to dorsal parietal areas Damage to the posterior parietal lobe (or superior temporal gyrus) can lead to a striking global modulation of visual awareness called neglect, in which a patient completely ignores or does not respond to objects in the contralateral hemifield (Driver & Mattingley, 1998).
Where is 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.
What is the superior temporal gyrus supplied by?
middle cerebral artery
Arterial supply The superior temporal gyrus receives blood from the middle cerebral artery via all four main temporal branches: the temporopolar artery; anterior temporal artery, middle temporal artery and posterior temporal artery 2.
What does the right inferior temporal gyrus do?
This region of the brain corresponds to the inferior temporal cortex and is responsible for visual object recognition and receives processed visual information.
How are gyrus describe?
In neuroanatomy, a gyrus (pl. gyri) is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci (depressions or furrows; sg. Gyri and sulci create the folded appearance of the brain in humans and other mammals.
Where are the fusiform and superior temporal sulcus located?
The primary focus was the measurement of activity in the fusiform gyrus (FG), which is located on the ventral surface of the temporal lobe, and in the superior temporal sulcus (STS), which is located in the lateral aspect of the temporal lobe.
What is the function of the superior temporal gyrus?
Superior temporal gyrus (STG) is the site of auditory association cortex (and a site of multisensory integration) and thus necessarily plays some role in spoken word recognition. Evidence that its role extends beyond that of higher-level perceptual processing was found as early as 1871 by Karl Wernicke.
What is the frontal fusiform gyrus?
frontal gyrus any of the three (inferior, middle, and superior) gyri of the frontal lobe. fusiform gyrus one on the inferior surface of the hemisphere between the inferior temporal and parahippocampal gyri, consisting of a lateral (lateral occipitotemporal gyrus) and a medial (medial occipitotemporal gyrus) part.
What is the fufu sulcus?
fu·si·form gy·rus. An extremely long convolution extending lengthwise over the inferior aspect of the temporal and occipital lobes, demarcated medially by the collateral sulcus from the lingual gyrus and the anterior part of the parahippocampal gyrus, laterally by the inferior temporal sulcus from the inferior temporal gyrus.
