An inferior-superior colliculus circuit controls auditory cue-directed visual spatial attentionFei HuYang Dan
Structure and Function The superior colliculus (SC) is a layered structure, whereby the dorsal layers receive visual input and the intermediate and deep layers give rise to descending projections essential for the generation of an orienting response to an object of visual or auditory interest (Figure...

In terms of output or efferents, both superior colliculi have axonal projections into various subcortical structures, such as the, reticular formation, spinal cord, lateral geniculate nucleus, and pulvinar of the thalamus. The pulvinar is regarded as a center of image interpretation that helps the ...
In the guinea-pig two subcortical structures have been shown to contain representations of auditory space, the deep layers of the superior colliculus (SC) and the external nucleus of the inferior colliculus (ICX). The following investigation was undertaken to determine if the ICX influences the dev...
Contribution of striate cortex and the superior colliculus to visual function in area MT, the superior temporal polysensory area and inferior temporal cortex We studied the visual responses of single neurons in three extra-striate visual areas of the macaque following lesions of striate cortex, lesion...
Pax7 encodes a transcription factor well-established as an important determinant of mesencephalic identity and superior collicular development. Pax7 mutant mice, however, present with no obvious morphological impairments to the superior colliculus. This
The largest targets of retinal input in mammals are the dorsal lateral geniculate nucleus (dLGN), a relay to the primary visual cortex (V1), and the superior colliculus. V1 innervates and influences the superior colliculus. Here, we find that, in turn, superior colliculus modulates responses...
Excitatory–excitatory interactions in the MSO are associated with peak-type responses, and excitatory–inhibitory interactions in the LSO are associated with trough-type responses. There are also neurons with responses intermediate between peak- and trough-type. In the inferior colliculus (IC), the ...
Normal projection development from the medial superior olive (MSO) to the inferior colliculus (IC) was examined by injecting Fluoro-Gold (FG), a retrograde tracer, into the IC unilaterally at postnatal days 0 (P0), P3, P7 and maturity. The rats were killed 1 day after FG injection. At ...
