Frontal eye fields

Information about Frontal eye fields

Brain:
Frontal eye fields is roughly equivalent to regions (at upper left) #6, #8 (in particular), and #9
Dorlands/Elsevier f_07/12363804
The frontal eye fields (FEF) is a region located in the dorsolateral frontal cortex of the primate brain reported to be activated during the initiation of eye movements, such as voluntary saccades and pursuit eye movements. The FEF constitutes together with the supplementary eye fields (SEF) and the intraparietal sulcus (IPS) one of the three most important cortical areas involved in the generation of eye movements.

The frontal eye fields show weak topographic organization, unlike the superior colliculus and parietal cortex that are also involved in saccadic eye movements.
