Text contexts

An analysis of effective connectivity demonstrated that the search-dependent variance in the activity of the superior colliculus was significantly influenced by the activity in a network of cortical regions including the right frontal eye fields and bilateral parietal and occipital corticesDarren R. Gitelman; Todd B. Parrish; Karl J. Friston; M-Marsel Mesulam. Functional anatomy of visual search: regional segregations within the frontal eye fields and effective connectivity of the superior colliculus. NeuroImage 15(4):970-82, 2002. PMID: 11906237. DOI: 10.1006/nimg.2001.1006. WOBIB: 3.
These experiments also revealed the presence of a mosaic of activated sites within the frontal eye field region wherein saccadic eye movements, covert shifts of attention, and visuomotor search elicited overlapping but not identical zones of activationDarren R. Gitelman; Todd B. Parrish; Karl J. Friston; M-Marsel Mesulam.

Pursuit performance, relative to visual fixation, elicited activation in three areas known to contribute to eye movements in humans and in nonhuman primates: the frontal eye field, supplementary eye field, and intraparietal sulcusR.

Human Brain Mapping 8(4):209-25, 1999. PMID: 10619415. WOBIB: 46.
The spatial extent of activation was similar for saccades and pursuit in all but two regions: spatial extent was greater for saccades in the superior branch of the frontal eye field and greater for pursuit in posterior cingulate cortexR.

Human Brain Mapping 8(4):209-25, 1999. PMID: 10619415. WOBIB: 46.
The most notable activation during the saccade suppression task, compared to central fixation alone, was a bilateral activation of the parietal cortex with a right-sided preponderance, activation of the supplementary eye field/caudal cingulate regions, and activation of frontal regions close to the frontal eye fieldsIan Law; Claus Svarer; Søren Holm; Olaf B. Paulson. The activation pattern in normal humans during suppression, imagination and performance of saccadic eye movements. Acta Physiologica Scandinavica 161(3):419-434, 1997. PMID: 9401596. FMRIDCID: . WOBIB: 135.
Imagined performance of eye movements without overt eye movements activated the supplementary eye field and frontal eye fields identically to regions involved in overt eye movements, thus demonstrating that over eye movements are not a prerequisite of the activation of these regions in normal humansIan Law; Claus Svarer; Søren Holm; Olaf B. Paulson. The activation pattern in normal humans during suppression, imagination and performance of saccadic eye movements. Acta Physiologica Scandinavica 161(3):419-434, 1997. PMID: 9401596.
