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 ...

Current Biology
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 ...

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

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.

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

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.

Superior colliculus lesions preferentially disrupt multisensory orientation
Neuroscience, 2004The general involvement of the superior colliculus (SC) in orientation behavior and the striking parallels between the multisensory responses of SC neurons and overt orientation behaviors have led to assumptions that these neural and behavioral changes are directly linked.
