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 ...

Parabigeminal projections to the superior colliculus in the cat
Brain Research, 1983Small amounts of horseradish peroxidase were injected into the superior colliculus of the cat and the distribution of labeled neurons in the parabigeminal nuclei was mapped. After injections placed dorsal to the stratum opticum in the superior colliculus, the parabigeminal nucleus is the only mesencephalic and/or rhombencephalic structure in which ...

Presenting information amassed from more than 30 years of research, this book gathers together the most important pieces of evidence regarding the structure and function of the superior colliculus. It explores the involvement of the superior colliculus in the control of gaze shift and rapid eye movements and provides a detailed discussion of structural

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 commissure of the superior colliculus in the hamster
Journal of Comparative Neurology, 2005AbstractThe development of the corpus callosum (CC) and the anterior commissure (CA) is well known in a wide variety of species. No study, however, has described the development of the commissure of the superior colliculus (CSC) from embryonic state to adulthood in mammals. In this study, by using the lipophylic tracer DiI, we investigated the ontogeny

Attentional Functions of the Superior Colliculus
2014The superior colliculus (SC) plays an important role in both overt and covert attention. In primates, the SC is well known to be a central component of the motor pathways that orient the eyes and head to important objects in the environment. Accordingly, neurons in the SC show enhanced responses that will be the target of orienting movements, compared ...

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 ...

Trigeminal projections to the superior colliculus of the rat
Journal of Comparative Neurology, 1981AbstractThe deep layers of the rodent superior colliculus contain a vibrissae‐related organization that is in “spatial register” with the overlying visuotopic organization (Dräger and Hubel, '76). The distribution of vibrissae‐related afferents and their cells of origin were determined with a number of anatomical techniques.

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

Movement Perception in the Colliculus Superior
IFAC Proceedings Volumes, 1977Summary Neurophysiological measurements on cats' colliculus superior show results which are dependent on the movement of visual stimuli and movement of the background as well as on the movement of stimulus and background n!lative to each other. The movement dependent problems involved in pattern recognition by space time filters as regards resolution
