The comparative anatomy of frontal eye fields in primates
2019, CortexCitation Excerpt :Dozens of studies have since come to corroborate this description both in PET and with the advent of fMRI (Fig. 4). Thanks to its higher spatial resolution, fMRI allowed to progressively restrict the site hosting the FEF along the precentral sulcus (Darby et al., 1996; Müri et al., 1996), at the junction with the superior frontal sulcus (Berman et al., 1999; Gitelman, Parrish, Labar, & Mesulam, 2000; Petit, Clark, Ingeholm, & Haxby, 1997). Interestingly, Luna et al. observed that performing visually-guided saccades co-activates the peri-precentral cortex at the junction with the superior frontal sulcus and to a lesser extent, more laterally, in the convexity of the precentral gyrus (Luna et al., 1998).

2018, Multiple Sclerosis and Related DisordersCitation Excerpt :According to functional studies, BA 17 clearly participates in the detection of light intensity (Goodyear and Menon, 1998; Morita et al., 2000), color recognition (Claeys et al., 2004; Schluppeck and Engel, 2002) and detection of visual patterns (Fokin et al., 2007). It also participates in movement tracking (Darby et al., 1996) and visual attention (Ciaramitaro et al., 2007; Silver et al., 2007). The cerebellum is a structure located in the posterior part of the brain, underlying the occipital and temporal lobes of the cerebral cortex.
Instruction dependent activation during optokinetic nystagmus (OKN) stimulation: An FMRI study at 3 T
2010, Brain ResearchCitation Excerpt :We found significant activation for look OKN in the cingulate gyrus which has previously been associated with voluntary smooth pursuit eye movements (Tanabe et al., 2002). Also, activation was seen for look OKN in the precuneus, which is known to be activated in voluntary saccadic (Anderson et al., 1994; Darby et al., 1996; Luna et al., 1998; Petit et al., 1996) and voluntary pursuit (Petit and Haxby, 1999) eye movements. The current study results agree with previous studies of voluntary eye movements as they relate to look OKN and provide external validity for the look OKN portion of the study.
