What is the superior temporal sulcus responsible for?
The superior temporal sulcus (STS) is implicated in a variety of social processes, ranging from language perception to simulating the mental processes of others (theory of mind). In a new study, Deen and colleagues use fMRI to show a regular anterior-to-posterior organization in the STS for different social tasks.
What is the posterior superior temporal sulcus?
The STS is located under the lateral fissure, which is the fissure that separates the temporal lobe, parietal lobe, and frontal lobe. The STS has an asymmetric structure between the left and right hemisphere, with the STS being longer in the left hemisphere, but deeper in the right hemisphere.
What happens if the superior temporal gyrus is damaged?
Disorders of auditory perception: Lesions of the left superior temporal gyrus produce problems of speech perception with difficulty in discriminating speech and the temporal order of sounds impaired. Lesions of the right superior temporal gyrus produce prosody.
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).
Is there a middle temporal sulcus?
The term middle temporal sulcus refers to the central of three short sulci on the ventrolateral surface of the temporal lobe of the macaque. The middle sulcus is topologically equivalent to the central part of the inferior temporal sulcus of the human ( Ono-1990 ). It is not found in the rat or mouse ( NeuroNames ).
Where is the superior temporal gyrus located?
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 sulcus located in the brain?
The superior temporal sulcus 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.
Where is posterior superior temporal sulcus?
Temporal Lobes The superior temporal sulcus lies above the superior temporal gyrus and electrical stimulation of this gyrus (especially in the posterior half) in the left hemisphere of typical right-handers often causes speech arrest or other alterations of language abilities.
Can temporal lobe damage be reversed?
While temporal lobe damage cannot be reversed, functions affected by the damage can be reorganized and relearned by healthy regions of the brain. The brain possesses a dynamic ability to heal itself and allow undamaged portions of the brain to take over control of damaged functions called neuroplasticity.
What can happen if the temporal lobes are damaged?
Right temporal damage can cause a loss of inhibition of talking. The temporal lobes are highly associated with memory skills. Left temporal lesions result in impaired memory for verbal material. Right side lesions result in recall of non-verbal material, such as music and drawings.
What are the symptoms of temporal lobe damage?
Damage to the temporal lobes can result in:
- Difficulty in understanding spoken words (Receptive Aphasia)
- Disturbance with selective attention to what we see and hear.
- Difficulty with identification and categorisation of objects.
- Difficulty learning and retaining new information.
- Impaired factual and long-term memory.
What makes up the superior temporal gyrus?
The superior temporal gyrus contains the auditory cortex, which is responsible for processing sounds. Specific sound frequencies map precisely onto the auditory cortex. The superior temporal gyrus also includes Wernicke’s area, which (in most people) is located in the left hemisphere.
What is the anatomical term for the superior temporal sulcus?
Anatomical terms of neuroanatomy. 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.
Which is part of the brain has superior sulcus?
The superior temporal sulcus is the sulcus separating the superior temporal gyrus from the middle temporal gyrus in the temporal lobe of the brain.
Which is the sulcus inferior to the lateral fissure?
Description. The superior temporal sulcus is the first sulcus inferior to the lateral fissure. The superior temporal sulcus runs from before backward across the temporal lobe, some little distance below, but parallel with, the posterior ramus of the lateral fissure; and hence it is often termed the parallel sulcus.
When does the superior temporal sulcus activate in autism?
In individuals without autism, 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.
