Anatomical structure in the human brain
The middle frontal gyrus is a part of the frontal lobe of the human brain. It is located between the superior frontal gyrus and the inferior frontal gyrus. The middle frontal gyrus plays a significant role in various cognitive functions, including attention, working memory, and executive functions.
Anatomy[edit]
The middle frontal gyrus is situated in the frontal lobe, which is the largest lobe of the brain. It is bounded by the superior frontal sulcus above and the inferior frontal sulcus below. The gyrus extends from the precentral sulcus in the anterior direction towards the frontal pole.
Structure[edit]
The middle frontal gyrus is composed of gray matter, which contains the cell bodies of neurons. It is part of the cerebral cortex, the outermost layer of the brain responsible for higher-order brain functions. The gyrus is involved in the integration of sensory and motor information and is crucial for planning and decision-making processes.
Function[edit]
The middle frontal gyrus is involved in several cognitive processes:
- Attention and Working Memory: It plays a role in maintaining attention and working memory, which are essential for tasks that require the temporary storage and manipulation of information.
- Executive Functions: The gyrus is involved in executive functions, which include planning, decision-making, and problem-solving.
- Language Processing: Although not primarily a language area, the middle frontal gyrus contributes to language processing and comprehension.
Clinical Significance[edit]
Damage to the middle frontal gyrus can result in deficits in attention, working memory, and executive functions. Lesions in this area may lead to difficulties in planning and organizing tasks, as well as impairments in decision-making abilities.
Imaging[edit]
The middle frontal gyrus can be visualized using various neuroimaging techniques such as MRI and CT scan. These imaging modalities help in assessing the structure and function of the gyrus in both healthy and diseased states.
