Brodmann area 8. 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]
contralateral frontal eye field of the middle frontal gyrus of the frontal lobe (via frontopontine fibers [6] The frontal eye field meanwhile receives afferents from the visual cortex. [7] superior colliculus [6] vestibular nuclei [6] other parts of the reticular formation. [6]
The FEF control voluntary eye movements, including saccades, smooth pursuit and vergence. OMA can also be associated with bilateral hemorrhages in the parietal eye fields (PEF). The PEF surround the posterior, medial segment of the intraparietal sulcus. They have a role in reflexive saccades, and send information to the FEF.
You don't necessarily need to see an eye doctor every year, but it's important to get checked out at some point, Dr. Alice Lorch, a comprehensive ophthalmologist at Mass Eye and Ear, tells Yahoo ...
Figure 1. Motor Cortex of the Monkey Brain: Pictured above are the approximate locations of the SEF and FEF in the monkey brain which we know today.. 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.
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 ...
