Frontal eye fields
open-in-new
<p>The frontal eye fields (FEF) are a region located in the <a href="/facts/Frontal_cortex/RvokInmf">frontal cortex</a>, more specifically in <a href="/facts/Brodmann_area_8/3zPfsWTx">Brodmann area 8</a> or BA8, of the primate <a href="/facts/Brain/EKla9NkJ">brain</a>. In humans, it can be more accurately said to lie in a region around the intersection of the <a href="/facts/Middle_frontal_gyrus/tqMt8T6P">middle frontal gyrus</a> with the <a href="/facts/Precentral_gyrus/ljM2xtgB">precentral gyrus</a>, consisting of a frontal and parietal portion. The FEF is responsible for <a href="/facts/Saccade/0YxQJpk2">saccadic eye movements</a> for the purpose of visual field perception and awareness, as well as for voluntary eye movement. The FEF communicates with extraocular muscles indirectly via the <a href="/facts/Paramedian_pontine_reticular_formation/MDzEpW28">paramedian pontine reticular formation</a>. Destruction of the FEF causes deviation of the eyes to the ipsilateral side. </p>
