The superior colliculus ('colliculus'), or optic tectum, is a highly conserved area of the brain that is critical for the organization and control of attention and orienting behaviors. It lies at the top of the midbrain and our understanding of its structure and function is based on work from many vertebrate species including: lampreys, fish ...

Development of the Superior Colliculus
Annual Review of Neuroscience, 1984Reference is often made to a study by Adamiik (1872) to illustrate how long we have known that the superior colliculus (SC) plays a role in eye movements. The interest in the involvement of the SC in eye movements has not waned, but has actually increased as a result of recent work describing the activity of SC cells in behaving animals (for ...

Parvalbumin in rat superior colliculus
Neuroscience Letters, 1990Parvalbumin-like immunoreactivity (PA-LI) has been studied in sections of the superior colliculus (SC) of the rat and its distribution compared to the patterns of acetylcholinesterase (AChE) and cytochrome oxidase (CO) staining. In the intermediate layers it was found that PA-LI is spatially associated with AChE only in the medial part of the SC, but ...

Superior colliculus efferents to the hypothalamus
Neuroscience Letters, 1979The projection of the superior colliculus to the hypothalamus was studied in the rabbit and rat with light and electron microscopic techniques. This projection system, as demonstrated with the anterograde transport of tritiated leucine, proline, adenosine or horseradish peroxidase, is primarily to dendrites located in the ipsilateral optic and ...

Calcium Imaging in Mouse Superior Colliculus
Journal of Visualized Experiments, 2023The superior colliculus (SC), an evolutionarily conserved midbrain structure in all vertebrates, is the most sophisticated visual center before the emergence of the cerebral cortex. It receives direct inputs from ~30 types of retinal ganglion cells (RGCs), with each encoding a specific visual feature.

Journal of Comparative Neurology, 1977
AbstractThe rate of acquisition of visual form discriminations in cats with superior colliculus damage was measured in a testing apparatus requiring a minimal amount of stimulus localization in space. In animals with bilateral superior colliculus ablations, acquisition was impaired relative to acquisition in normal animals. In these animals, the extent

Visuovestibular interactions in the cat superior colliculus.
Journal of Neurophysiology, 19741. Single-unit recording has been performed from the superficial layers of the superior colliculus of regionally anesthetized cats. The response of the collicular units to a luminous bar moving in its receptive field has been analyzed as a function of the position of rotation of the animal about its longitudinal axis. 2.

Efferent projections of the superior colliculus in the opossum
Journal of Comparative Neurology, 1970AbstractThe Fink and Heimer technique was used to study the ascending and descending fiber degenerations resulting from unilateral electrolytic lesions in the superior colliculus of sixteen adult opossums. The ascending fiber degeneration left the colliculus by way of a small parabrachial bundle or with the brachium of the superior colliculus.

Superior Colliculus: Visuotopic-Somatotopic Overlap
Science, 1975A laminar organization was present in the superior colliculus of the cat, with upper layer cells exclusively visual, lower layer cells primarily somatic (or acoustic), and intermediate layers showing significant modality overlap. The close topographic correspondence between the visual and somatic representations observed within this laminar pattern and

Cholinergic innervation of the superior colliculus in the cat
Journal of Comparative Neurology, 1989AbstractThe superficial and intermediate gray layers of the superior colliculus are heavily innervated by fibers that utilize the neurotransmitter acetylcholine. The distribution, ultrastructure, and sources of the cholinergic innervation of these layers have been examined in the cat by using a combination of immunocytochemical and axonal transport ...
