The superior temporal sulcus, and often the temporoparietal junction, is a brain region that is important for numerous aspects of social cognition. This region is typically active during tasks of cognitive empathy and perspective-taking (Frith & Frith, 2006; Saxe & Kanwisher, 2003).
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).
What is the role 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 temporal sulcus?
The superior temporal sulcus (STS) is the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe of the brain.
What is the superior temporal cortex?
The superior temporal gyrus contains the auditory cortex, which is responsible for processing sounds. The superior temporal gyrus also includes Wernicke’s area, which (in most people) is located in the left hemisphere. It is the major area involved in the comprehension of language.
Why is the temporal lobe important?
The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception. The dominant temporal lobe, which is the left side in most people, is involved in understanding language and learning and remembering verbal information.
What disorders are associated with the temporal lobe?
Kolb & Wishaw (1990) have identified eight principle symptoms of temporal lobe damage: 1) disturbance of auditory sensation and perception, 2) disturbance of selective attention of auditory and visual input, 3) disorders of visual perception, 4) impaired organization and categorization of verbal material, 5) …
What makes up the superior temporal gyrus?
Where is the superior temporal gyrus?
temporal lobe
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.
Where is the superior temporal line?
The superior temporal line is an arching ridge along the lateral surface of the skull; it begins as a continuation of the upper posterior border of the zygomatic bone and continues as a broad arch along the frontal and parietal bones, above and roughly parallel to the upper edge of the temporal bone.
What is the superior temporal sulcus (STS)?
The superior temporal sulcus ( STS) is the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe of the brain. The superior temporal sulcus is the first sulcus inferior to the lateral fissure . Recent studies reveal multisensory processing capabilities.
Is the superior temporal sulcus activated in children with autism?
Children with high-functioning autism have been reported to have no significant change in superior temporal sulcus activation for biological motion compared to non-biological motion, which suggests that the superior temporal sulcus is not specifically activated in the processing of biological motion like it is in children without autism.
Why does the superior temporal sulcus activate when hearing human voices?
The superior temporal sulcus also activates when hearing human voices. It is thought to be a source of sensory encoding linked to motor output through the superior parietal-temporal areas of the brain inferred from the time course of activation.
What is the difference between the sulcus and gyrus?
A sulcus (plural sulci) is a deep groove that curves into the largest part of the brain, the cerebrum, and a gyrus (plural gyri) is the a ridge that curves outward of the cerebrum. The STS is located under the lateral fissure, which is the fissure that separates the temporal lobe, parietal lobe, and frontal lobe.
