What does the frontal eye field area do?
What does the frontal eye field area do?
The frontal eye field (FEF) is an area of the frontal cortex in animals over which electrical stimulation is able to trigger eye movements.
What happens if the frontal eye field is damaged?
Damage to the frontal eye fields will cause deficits in voluntary eye movement to the contralateral visual field (leading to active visual search deficits), but preserved passive eye movement (as in the following of a moving object).
What area of the brain is responsible for saccades?
The parietal lobe and more particularly its posterior part, the PPC, are involved in the control of saccades and attention.
Does the frontal lobe control eye movement?
In the frontal lobe, three main areas are involved in eye movement control [2]: the frontal eye field (FEF), the supplementary eye field (SEF) and the dorsolateral prefrontal cortex (DLPFC).
What stimulates frontal eye fields?
Electrical stimulation in the FEF elicits saccadic eye movements. The FEF have a topographic structure and represents saccade targets in retinotopic coordinates. The frontal eye field is reported to be activated during the initiation of eye movements, such as voluntary saccades and pursuit eye movements.
Where are frontal eye fields?
primate prefrontal cortex
The Frontal Eye Field (FEF) is a region of primate prefrontal cortex defined as the area in which low-current electrical stimulation evokes saccadic eye movements.
Where is frontal eye field located?
premotor cortex area 8
The frontal eye fields (FEFs), located in premotor cortex area 8, initiate contraversive horizontal eye deviation.
What are the 5 functional areas of the frontal lobe?
On its surface, the frontal lobe contains four principal gyri: the precentral, superior frontal, middle frontal, and the inferior frontal gyrus. The functions of the frontal lobe are numerous. It is associated with higher cognitive functions, such as decision making, motivation, problem-solving, planning and attention.
What causes eye saccades?
A reflexive saccade occurs when your eyes look at something new that appears in your field of vision, or when you hear something that causes you to react. These saccades are largely unconscious, driven by functions lower down in the brainstem.
Which part of the brain helps in eye movement?
Within the frontal cortex, the cortical structures of the saccadic systems include; the frontal eye field (FEF) and its role in saccade and pursuit eye movement control, the supplementary eye field (SEF) and the dorsolateral prefrontal cortex (dlPFC).
What part of the brain affects eye movement?
The cerebellum plays a pivotal role in the control of eye movements. Its core function is to optimize ocular motor performance so that images of objects of interest are promptly brought to the fovea – where visual acuity is best – and kept quietly there, so the brain has time to analyze and interpret the visual scene.
What is the frontal eye field of the brain?
The Frontal Eye Field (FEF) is a region of primate prefrontal cortex defined as the area in which low-current electrical stimulation evokes saccadic eye movements.
