|The superior colliculus showed prominent activation in the search versus eye movement contrast, demonstrating, for the first time in humans, activation of this region specifically related to an exploratory attentional contingency||Darren 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.|
|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 cortices||Darren 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.

|Enhanced haemodynamic responses during attentive conditions defined an occipitoparietofrontal system, including sensory and association areas, as well as the medial thalamus and superior colliculus||Christian Büchel; Oliver Josephs; G. Rees; R. Turner; C. D. Frith; Karl J. Friston. The functional anatomy of attention to visual motion. A functional MRI study. Brain 121 ( Pt 7):1281-94, 1998. PMID: 9679780. WOBIB: 24.|
|We observed an interaction between the predictability of stimuli and self-generated actions in several areas, including the medial posterior cingulate cortex, left insula, dorsomedial thalamus, superior colliculus and right inferior temporal cortex||S. J. Blakemore; G. Rees; C. D. Frith. How do we predict the consequences of our actions? A functional imaging study. Neuropsychologia 36(6):521-9, 1998. PMID: 9705062. WOBIB: 82.|
