The involvement of the superior colliculi in hemispherectomized subjects with blindsight
Journal of Vision, 2010 Purpose: The ability in cortically blind patients to respond to visual stimuli without consciously experiencing has been termed ‘blindsight’. The goal of this study is to investigate the involvement of the superior colliculi (SC) in mediating blindsight ...

Functional MRI of postnatal visual development in normal rat superior colliculi [PDF]
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009 Theme: Engineering the Future of BiomedicineThis study employed blood oxygenation level-dependent functional MRI (BOLD-fMRI) to evaluate the visual responses in the superior colliculus of the developing rat brain from the time of eyelid opening to ...

Visual pattern discrimination in cats after removal of the superior colliculi [PDF]
Psychonomic Science, 1971 Two groups of cats were trained to make a visual discrimination between two patterns in a standard discrimination apparatus. Animals in Group I were trained until they reached a criterion level of 90% correct responding, had bilateral lesions made in the superior colliculi (SC), and were retrained.

Effects of damage to superior colliculi and pre-tectum on movement discrimination in rhesus monkeys [PDF]
Experimental Brain Research, 1984 Eight rhesus monkeys (Macaca mulatta) were trained to detect an instantaneous lateral displacement of a small spot of light. The smallest movement for 79% correct performance was then determined. Severing the splenium of the corpus callosum, which has to be done to reveal the superior colliculi, had no effect on the movement threshold.

The Journal of Physiology, 1976 1. Irregular light falshes were played on to one eye of dark adapted rabbits for periods of 20‐80 min. The concentration of 5‐hydroxyindol‐3‐ylacetic acid (5‐HIAA) and of 5‐hydroxytryptamine (5‐HT) were estimated in left and right superior colliculi, thalami and hippocampi. 2.

Origin and terminal distribution of the trigeminal projections to the inferior and superior colliculi in the lesser hedgehog tenrec [PDF]
European Journal of Neuroscience, 1998 AbstractThe trigemino‐tectal projections were investigated with anterograde and retrograde tracing techniques in the Madagascan lesser hedgehog tenrec, Echinops telfairi. There were prominent contralateral projections to the inferior colliculus (CoI) and the superior colliculus (CoS), each showing its own characteristic pattern of terminations.
