Supplementary eye field (SEF) is the name for the anatomical area of the dorsal medial frontal lobe of the primate cerebral cortex that is indirectly involved in the control of saccadic eye movements. Evidence for a supplementary eye field was first shown by Schlag, and Schlag-Rey. [1]
Medial eye fields are areas in the frontal lobe of the primate brain that play a role in visually guided eye movement. [1] Most neuroscientists refer to this area as the supplementary eye fields . Eye fields are divided into two hemispheres regulated by s onic hedgehog ( Shh ) and Six3 .
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 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).
Saccadic eye movements and anti-saccadic eye movements are carried out by similar regions of the brain: the frontal eye field (FEF), the supplementary motor area (SMA), the thalamus and putamen. Anti-saccades involve two important cognitive functions: the ability to form an intention and the ability to inhibit a reflexive response.
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 ...
