The superior colliculus (SC) is a midbrain center that integrates sensory input and transforms the information into a command signal to initiate behaviors, such as orienting to an object that attracts attention or escaping from a predator. It is a laminar structure composed of two primary layers: the superficial layer and the deeper layer.

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.

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 ...

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.

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 ...

Intrinsic processing in the mammalian superior colliculus
Current Opinion in Neurobiology, 2002The mammalian superior colliculus receives visual inputs from the retina and primary visual cortex in its superficial layers and sends descending motor commands from its deeper layers. It is now becoming clear that a connection exists between these layers, but the signal transmission through it is not robust.

The role of the superior colliculus in predatory hunting
Neuroscience, 2010Combining the results of behavioral, neuronal immediate early gene activation, lesion and neuroanatomical experiments, we have presently investigated the role of the superior colliculus (SC) in predatory hunting. First, we have shown that insect hunting is associated with a characteristic large increase in Fos expression in the lateral part of the ...
