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 ...
The maps for visual areas are retinotopic, meaning that they reflect the topography of the retina: the layer of light-activated neurons lining the back of the eye. In this case too, the representation is uneven: the fovea—the area at the center of the visual field—is greatly overrepresented compared to the periphery. The visual circuitry in ...
The corticomesencephalic tract originates from the frontal eye field in the caudal part of the middle frontal gyrus and the inferior frontal gyrus (Brodmann's area 8). [2] It runs rostral to the pyramidal tract in the posterior limb of the internal capsule.
V5's outputs include V4 and its surrounding area, and eye-movement motor cortices (frontal eye-field and lateral intraparietal area). V5's functionality is similar to that of the other V's, however, it integrates local object motion into global motion on a complex level. V6 works in conjunction with V5 on motion analysis.
The frontal eye field plays a very important role when it comes to eye movements. [9] Particularly the frontal eye field is responsible for much of the saccadic eye movements that eyes make. [10] Once the frontal eye field is activated by the corollary discharge signal, it sends a predictive signal to the occipital lobe. This signal essentially ...
Interaction between dorsal and ventral attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation. [1]The dorsal attention network (DAN), also known anatomically as the dorsal frontoparietal network (D-FPN), is a large-scale brain network of the human brain that is primarily composed of the intraparietal sulcus (IPS) and frontal eye ...
In dichoptic visual masking, the target is presented to one eye and the mask to the other, whereas in monoptic visual masking, both eyes are presented with the target and the mask. It was found that the masking effect was just as strong in dichoptic as it was in monoptic masking, and that it showed the same timing characteristics. [6] [7] [8]
