- Supplementary eye fields
Supplementary eye fields (SEF) are areas on the dorsal-medial surface of
frontal lobe of the primatebrain that are involved in planning and control of saccadiceye movements . The SEF was first characterized by John Schlag and colleagues as an area where low intensity electrical stimulation can evoke saccades, similar to the more lateralfrontal eye fields [Schlag J, Schlag-Rey M.(1987) Evidence for a supplementary eye field. J Neurophysiol. 57(1):179-200.] . More recently it was shown that SEF stimulation produces coordinated gaze movements of both the eyes and head [Martinez-Trujillo JC, Wang H, Crawford JD. (2003) Electrical stimulation of the supplementary eye fields in the head-free macaque evokes kinematically normal gaze shifts. J Neurophysiol. 89(6):2961-74.] . Neural recordings in the SEF show signals related to both vision and saccades somewhat like the frontal eye fields andsuperior colliculus , but currently most investigators think that the SEF has a special role in high level aspects of saccade control, like complex spatial transformations [Olson CR, Gettner SN. *1995) Object-centered direction selectivity in the macaque supplementary eye field. Science. 269(5226):985-8.] , learned transformations [Chen LL, Wise SP. (1995) Neuronal activity in the supplementary eye field during acquisition of conditional oculomotor associations. J Neurophysiol. 73(3):1101-21.] , and executive cognitive functions [Stuphorn V, Schall JD. (2006) Executive control of countermanding saccades by the supplementary eye field. Nat Neurosci. 9(7):925-31.] .Notes
