Supplementary eye field

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.

Figure 2. Ferrier's Monkey Brain Map (1874).
The highlighted area labeled 'EF' is the area he observed to cause eye and head movements when electrically stimulated.[9]

Figure 3. Brodmann Brain Map: The SEF is located in the rostral supplementary motor area which corresponds to Area 6 in the above map. For reference, the FEF is located in Area 8.

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. Current research strives to explore the SEF's contribution to visual search and its role in visual salience. The SEF constitutes together with the frontal eye fields (FEF), the intraparietal sulcus (IPS), and the superior colliculus (SC) one of the most important brain areas involved in the generation and control of eye movements, particularly in the direction contralateral to their location. Its precise function is not yet fully known. Neural recordings in the SEF show signals related to both vision and saccades somewhat like the frontal eye fields and superior colliculus, but currently most investigators think that the SEF has a special role in high level aspects of saccade control, like complex spatial transformations, learned transformations, and executive cognitive functions.
