(7) Middle frontal gyrus - angular gyrus
: A region of the cerebral cortex involved in attention function.
Before the intervention found that areas related to anomia were the superior frontal gyrus, the angular gyrus
and the superior temporal gyrus and a half I left mainly hemisphere.
Right CAU had strong positive correlations with the right postcentral gyrus (POST), anterior cingulate gyrus (ACG), hippocampus (HIP), and INS, left THA, and bilateral frontal lobe, angular gyrus
(AG), supramarginal gyrus (SMG), occipital lobe, and PUT.
This condition leaves patients with preserved visual recognition and writing skills, but impaired ability to read due to a loss of visual input to the language area of the left angular gyrus
The activation map for correct naming before therapy showed the recruitment of a large set of areas, including bilateral activation of the angular gyrus
, superior parietal lobule, premotor cortex, left middle and inferior occipital gyri, and right cerebellum.
Significant decreased white matter volumes was found in the right angular gyrus
t(28)= 4.35, p<.0001 and in the right superior temporal gyrus t(28)= 3.93, p<.0001.
One of the branches supply the angular gyrus
while the other supplies the supramarginal gyrus, posterior superior temporal gyrus, and the parietooccipital arcus (Sulcus).
Recent findings from functional MRI scans (fMRI) and magnetoencephalography (MEG) have suggested the angular gyrus
, a region of the brain known to be involved in language, number processing and spatial cognition, memory retrieval and attention, as a potential hub for semantic memory integration, specifically the left angular gyrus
The implication of prefrontal structures and the angular gyrus
in emotional memory may indicate the relevance of these regions in autobiographical processing.
This bundle, which connects the angular gyrus
(AG) to the region of the temporo-occipital junction on the lateral surface, was considered the anterior and superficial edge to the occipital connectivity in our dissections.
The researchers said that the alteration in the connections between the posterior cingulate cortex and the right angular gyrus
is also observed in people with antisocial behavior and other cerebral areas that are usually activated when performing given cognitive tasks.
DMN involves PCC/PCUN, bilateral inferior parietal gyrus, angular gyrus
, middle temporal gyrus, superior frontal gyrus, and medial frontal gyrus .
