The superior frontal gyrus (SFG) may play a role in executive functions such as self-monitoring, working memory, organization, and planning. In a 2006 study, patients with left prefrontal lesions on the SFG exhibited poorer results on working memory tasks than the control group.
Brodmann area 8. The frontal eye fields (FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [1] of the primate brain.In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus, consisting of a frontal and parietal portion.

The inferior frontal gyrus includes Broca's area. On the inferior or ventral surface of the frontal lobe including the orbitofrontal cortex is the orbital gyrus. This is also called the orbital gyri because it is separated into four sections or gyri: anterior, posterior, lateral, and medial. The most medial gyrus of the frontal lobes on the ...
The frontal lobe can be divided into a lateral, polar, orbital (above the orbit; also called basal or ventral), and medial part. Each of these parts consists of a particular gyrus: Lateral part: lateral part of the superior frontal gyrus, middle frontal gyrus, and inferior frontal gyrus
Gerstmann's syndrome is caused by a lesion of the dominant (usually the left) parietal lobe, usually an angular gyrus lesion. [3] Apraxic agraphia with ideomotor apraxia is typically caused by damage to the superior parietal lobe (where graphomotor plans are stored) or the premotor cortex (where the plans are converted into motor commands). [1]
The results showed that a lesion in the subcortical white matter of the superior frontal gyrus was the cause of utilization behavior in the patient. A coronal section of the brain confirmed an infarct, tissue death due to lack of oxygen, in the left superior frontal gyrus with the main lesion in the subcortical white matter. [1]
The tumor and the surgery destroyed the left inferior and middle frontal gyrus, the head of the caudate nucleus, the anterior limb of the internal capsule, and the anterior insula. However, there were minimal language problems three months after removal and the individual returned to his professional work.
In this image, the angular gyrus is denoted by the double asterisk ** The angular gyrus is a region of the brain lying mainly in the posteroinferior region of the parietal lobe, occupying the posterior part of the inferior parietal lobule. [1] It represents the Brodmann area 39. [1]
