Where is the supramarginal gyrus located?
The supramarginal gyrus is located just anterior to the angular gyrus allowing these two structures (which compose the inferior parietal lobule) to form a multimodal complex that receives somatosensory, visual, and auditory inputs from the brain.
Is the left supramarginal gyrus a multimodal hub for spatial information?
Hence, the left supramarginal gyrus would then be a hub where visual spatial information is processed. Such a modality-specific hub fits with a multimodal representation of spatial information. However, if the left supramarginal gyrus also processes nonvisual spatial information, then a supramodal representation seems more plausible.
What happens when the right supramarginal gyrus is damaged?
Research has shown that disrupting the neurons in the right supramarginal gyrus causes humans to project emotions on others, inhibiting the ability to be empathetic. In addition, this disruption also causes people to be more egocentric, mainly because they are not able to perceive the emotions of those around them.
Why is the supramarginal gyrus important for reading comprehension?
Because the supramarginal gyrus and is one of the main areas together with the angular of the integration between visual and auditory material, its injury or dysfunction and are linked to alexia, which suppose the existence of severe difficulties when it comes to power interpret or read a text.
What is the angular gyrus responsible for?
The angular gyrus is a region of the brain in the parietal lobe, that lies near the superior edge of the temporal lobe, and immediately posterior to the supramarginal gyrus; it is involved in a number of processes related to language, number processing and spatial cognition, memory retrieval, attention, and theory of ...
What sulcus is surrounded by supramarginal gyrus?
The part surrounding the upturned end of the posterior ramus is known as the supramarginal gyrus, the part surrounding the superior temporal sulcus is known as the angular gyrus, and the part surrounding the posterior end of the inferior temporal sulcus known as pars temporal-occipitalis (6–9).
Is Wernicke's area in supramarginal gyrus?
Wernicke's area, of which the temporal planum is a key anatomical component, is located on the superior temporal gyrus, in the superior portion of Brodmann area 22.
What would happen if your angular gyrus was damaged?
Lesions causing damage to the angular gyrus can give rise to a constellation of symptoms. The classic symptoms include alexia with agraphia, constructional disturbances with or without Gerstmann's tetrad and behavioural manifestations such as depression, poor memory, frustration and belligerence.
What does the right supramarginal gyrus do?
The right supramarginal gyrus ensures that we can decouple our perception of ourselves from that of others. When the neurons in this part of the brain were disrupted in the course of this task, the participants found it difficult not to project their own feelings onto others.

What is the difference between Wernicke's and Broca's area?
Broca's and Wernicke's areas are cortical areas specialized for production and comprehension, respectively, of human language. Broca's area is found in the left inferior frontal gyrus and Wernicke's area is located in the left posterior superior temporal gyrus.
Is the Supramarginal gyrus in both hemispheres?
The supramarginal and angular gyri in the dominant hemisphere are known to participate to complex cognitive functions, such as calculation. In patients harboring left posterior parietal LGG, both multiplication and subtraction have been tested using IESM.
What is Wernicke's area responsible for?
Wernicke area, region of the brain that contains motor neurons involved in the comprehension of speech.
Where is the supramarginal gyrus located?
parietal lobeThe 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 artery supplies the angular gyrus?
the middle cerebral arteryThe blood supply to the angular gyrus arises from the middle cerebral artery; a primary branch of the internal carotid artery.
What causes left right disorientation?
The Gerstmann syndrome of dyscalculia, dysgraphia, left-right confusion, and finger agnosia is generally attributed to lesions near the angular gyrus of the dominant hemisphere.
