Frontal eye field. The frontal eye field is a posterior part of the middle frontal gyrus and is involved in the control of saccadic, contralateral and conjugate eye movement. This area receives its main inputs from both the occipital cortex and dorsal thalamus. [6] Broca's area
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. [ 2 ]
Brodmann area 8, or BA8, is part of the frontal cortex in the human brain. Situated just anterior to the premotor cortex , it includes the frontal eye fields (so-named because they are believed to play an important role in the control of eye movements). Damage to this area, by stroke, trauma or infection, causes tonic deviation of the eyes ...
Symptoms may happen spontaneously, or be due to a lesion or injured area of the occipital lobe. [4] For visual symptoms, these may include simple to complex hallucinations, blindness, visions, and palinopsia (seeing a visual stimulus after it has been removed from the visual field). These are usually brief, but can be experienced from 1–3 ...
Frontal release signs are primitive reflexes traditionally held to be a sign of disorders that affect the frontal lobes. The appearance of such signs reflects the area of brain dysfunction rather than a specific disorder which may be diffuse, such as a dementia, or localised, such as a tumor. [1] One reflex thought to have good localizing value ...
Foster Kennedy syndrome is a constellation of findings associated with tumors of the frontal lobe. [1]Although Foster Kennedy syndrome is sometimes called "Kennedy syndrome", [2] it should not be confused with Kennedy disease, or spinal and bulbar muscular atrophy, which is named after William R. Kennedy.
If any part of the brain that controls eye movement becomes damaged, then OMA may develop. [2] One of the potential causes is bifrontal hemorrhages. In this case, OMA is associated with bilateral lesions of the frontal eye fields (FEF), located in the caudal middle frontal gyrus. The FEF control voluntary eye movements, including saccades ...
Frontal lobe injuries have been shown to cause decreased ability in combining events that are temporally separated (separated by time), as well as recalling information in its correct context. However, standardized testing may mask or exaggerate a possible impairment because the patients are strictly regulated, as are their discretionary behaviors.
