Fef brain area
WebNov 11, 2016 · The frontal eye field (FEF) is an important brain area for making saccades to remembered locations. FEF neurons increase their firing rate during three epochs of memory-guided saccades: (i) target presentation, (ii) delay period, and (iii) motor preparation.Pharmacological inactivation of the FEF impairs memory-guided saccades (1 … WebWe tested whether the frontal eye field (FEF) is critical in controlling visual processing in posterior visual brain areas during the orienting of spatial attention.
