Is the frontal eye field in the prefrontal cortex?

Is the frontal eye field in the 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.

What part of the brain controls eye movements?

frontal lobe
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).

Is the frontal lobe located in the cerebral cortex?

Share on Pinterest The frontal lobe is located near the forehead and plays a vital role in motivation and memory. The frontal lobe is part of the brain’s cerebral cortex. Individually, the paired lobes are known as the left and right frontal cortex.

What does the frontal eye field of the brain do?

Function. The cortical area called frontal eye field (FEF) plays an important role in the control of visual attention and eye movements. The frontal eye field is reported to be activated during the initiation of eye movements, such as voluntary saccades and pursuit eye movements.

What is the frontal eye field involved in?

The frontal eye field (FEF) is an area of the frontal cortex in animals over which electrical stimulation is able to trigger eye movements. Finally, subcortical structures, such as the superior colliculus (SC) in the midbrain are also considered essential to trigger eye movements.

What does the frontal lobe of the brain control?

The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one’s responses in order to achieve a goal.

What is the function of the frontal eye fields?

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 does the frontal lobe consist of?

The frontal lobe is covered by the frontal cortex. The frontal cortex includes the premotor cortex, and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex.

Where is the frontal lobe of the brain?

The frontal lobes are located directly behind the forehead. The frontal lobes are the largest lobes in the human brain and they are also the most common region of injury in traumatic brain injury.

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).

How is the frontal eye field related to extrastriate visual areas?

Extrastriate visual areas are reciprocally connected with the frontal eye field. The frontal eye field is also connected with areas in the frontal lobe such as dorsolateral prefrontal cortex (DLPFC) and the supplementary eye field (SEF).

Who is the founder of the frontal eye field?

The frontal eye field (FEF) was described first in the late 1800s by David Ferrier, who discovered that electrical stimulation of a portion of the frontal lobe of macaque monkeys elicited movements of the eyes. Today we know that the FEF exists in all primates, including humans. A homolog of the FEF has been described in cats and owls too.

Where is the FEF located in the human brain?

In humans, the FEF is located in the rostral bank of a portion of the precentral sulcus at the caudal end of the middle frontal gyrus (Figure 1(b)). In macaque monkeys, the animal of choice for investigations of this part of the brain, the FEF occupies the rostral bank of the arcuate sulcus (Figure 1(a)).

When did David Ferrier discover the frontal eye field?

The frontal eye field (FEF) was described first in the late 1800s by David Ferrier, who discovered that electrical stimulation of a portion of the frontal lobe of macaque monkeys elicited movements of the eyes.
