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.

Possible plasticity in the rat superior colliculus
Nature, 1978THE potential for plasticity of the developing mammalian visual system has been the subject of several investigations1,2. I have now explored the plastic relationship between different sensory modalities. The rodent superior colliculus was chosen as the model as it receives overlapping visual, somatic and auditory inputs3,4.

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.

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: 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

Commissural connections of human superior colliculus
Neuroscience, 2002The superior colliculus of higher mammals is a laminated structure of the midbrain that receives visual input in superficial layers, and visual, auditory and somatosensory input in deep layers. The superior colliculi on either side are interconnected via the intercollicular commissure, which has been proposed to play a role in visual transfer and gaze ...

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 ...

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 ...

Visual System: Superior Colliculus
1978The primary visual brain of lower vertebrates is the optic lobe or optic tectum, an organ which receives visual input and helps generate visually guided behavior. The evolution of the cerebral cortex did not result in the elimination of the tectum, but instead, as the superior colliculus, the visual organ in the midbrain continues to play some function
