The Superior Colliculi and Eye Movements
Archives of Neurology, 1966 FOR ALMOST a century the superior colliculi have been considered as important structures in oculomotor functions. This concept originated in 1870 when Adamiik observed conjugate eye movements upon electric stimulation of the tectum.1It was then that the hypothesis of a gaze "center" was introduced and remained unchallenged until Bernheimer2and Ferrier ...

Functions of the Superior Colliculi in Vision

Archives of Surgery, 1939 The function of the collicular bodies of the quadrigeminal plate in man, and particularly that of the superior (or anterior) colliculi, remains undetermined. Not only has little experimental work been devoted to the problem, but little suitable human material has been available for study.

Neurogenetic gradients in the superior and inferior colliculi of the rhesus monkey
Journal of Comparative Neurology, 1981 AbstractThe spatiotemporal patterns of neurogenesis in the superior colliculus (SC) and inferior colliculus (IC) were analyzed by plotting the positions of heavily labeled neurons in autoradiograms from a series of rhesus monkeys that had been exposed to 3H‐thymidine at various embryonic (E) days and killed either shortly thereafter or at 2–3 months ...

Superior Colliculi Involvement in Poststroke Unilateral Spatial Neglect: A Pilot Study
Topics in Stroke Rehabilitation, 2011 The neural mechanisms underlying unilateral spatial neglect (USN) are unclear. The superior colliculi (SC) may be involved in USN expression, and the spatial summation effect (SSE), where reaction times to bilateral stimuli are faster than to unilateral, may be a behavioral index of SC function.

Single‐cell responses associated with rhythmic slow‐wave potentials in rat superior colliculi
Journal of Neuroscience Research, 1975 AbstractThe present study was designed to investigate the features of rhythmic slow‐wave potentials in the superior colliculi of rats and to study the relationship between these potentials and the activity of single collicular neurons. In contrast to studies in other portions of the visual system, rhythmic slow‐wave potentials in the colliculi fell ...

Differential color responses from the superior colliculi of squirrel monkeys
Vision Research, 1966Abstract Color sensitivity of the superior colliculi was investigated in squirrel monkeys. Evoked potentials were recorded from the colliculi in response to red and blue light stimulation. Color sensitivity of the superior colliculus was indicated by: differences in latency of potentials evoked by different color stimuli, differences in amplitude of ...

Scrapie inoculation of mice: light and electron microscopy of the superior colliculi
Acta Neuropathologica, 1991Ultrastructural examination of the superior colliculi of mice intraocularly inoculated with the ME7 strain of scrapie showed vacuolation early in the course of infection. Brains were examined between 85-260 days after monocular inoculation with scrapie. The mean incubation period for the development of clinical disease was 302 days.

Inferior and Superior Colliculi
1992In the classical neuroanatomical literature, the inferior and superior colliculi, located on the roof of the midbrain, are grouped together as the corpora quadrigemina. However, modern research indicates that these structures have quite different functions.

Effects of ablations of the superior colliculi on spectral sensitivity in monkeys
Neuropsychologia, 1975Abstract Spectral sensitivity of rhesus monkeys was determined before and after the total ablation of the superior colliculi. The hypothesis tested was that photopic spectral sensitivity would not be affected by the colliculectomy whereas the monkeys would loose scotopic sensitivity. This hypothesis was derived from the fact that photopic sensitivity
