supramarginal gyrus

The supramarginal gyrus is a portion of the parietal lobe.

It also branches to the supramarginal gyrus.

Language switching is another task in which brain activation is high in Broca's area and the supramarginal gyrus.

Recent research has challenged this notion on the basis that patients with conduction aphasia more often have lesions in the supramarginal gyrus or deep parietal matter.

Parietal lobe also assists with verbal short term memory and damage to the supramarginal gyrus cause short term memory loss.

The Inferior parietal lobule is concerned with language, mathematical operations, and body image, particularly the supramarginal gyrus and the angular gyrus.

Functional imaging experiments suggest that the left anterior supramarginal gyrus (aSMG) of the human inferior parietal lobule exhibits an evolved specialization related to tool use.

Damage to the inferior parietal region including the anterior (supramarginal gyrus) and posterior (angular gyrus) regions resulted in reduced SCR.

One to the branches supply the angular gyrus while the other supplies the supramarginal gyrus, posterior superior temporal gyrus, and the parietooccipital arcus (sulcus).

The supramarginal gyrus part of Brodmann area 40 is the region in the inferior parietal lobe that is involved in reading both in regards to meaning and phonology.

One, the supramarginal gyrus, arches over the upturned end of the lateral fissure; it is continuous in front with the postcentral gyrus, and behind with the superior temporal gyrus.

We report here that comparisons of distribution of cerebral blood flow in these conditions localized the phonological store to the left supramarginal gyrus whereas the subvocal rehearsal system was associated with Broca's area.

An analysis of performance scores in a pitch memory task resulted in a significant correlation between good task performance and the supramarginal gyrus (SMG) as well as the dorsolateral cerebellum.

This involves some of the same sites - prefrontal cortex (PFC), supramarginal gyrus (SMG), and other association areas - involved in the semantic selection stage of verb generation.

A major observation is lack of left hemisphere lateralization in major language structures such as the (inferior frontal gyrus-opercularis, inferior frontal gyrus-triangularis, supramarginal gyrus and superior temporal gyrus.

Neuroimaging techniques such as fMRI's, have shown that at least four brain areas are involved in bilingual switching: dorsolateral prefrontal cortex, inferior frontal cortex, anterior cingulate, and supramarginal gyrus.

The inferior part of BA40 is in the area of the supramarginal gyrus, which lies at the posterior end of the lateral fissure, in the inferior lateral part of the parietal lobe.

SLF III is the ventral component and originates in the supramarginal gyrus (rostral portion of the inferior parietal lobe) and terminates in the ventral premotor and prefrontal cortex (Brodmann 6, 44, and 46).

Passive perception of phonemes activated BA 22/42 bilaterally, whereas a rhyming task and a similar phonological judgement task, all performed silently, also activated Broca's area (left BA 44) but not the left supramarginal gyrus (left BA 40).
