Functional modulation of primary visual cortex by the superior colliculus in the mouse
Nature Communications, 2018 The role of the superior colliculus (SC) in modulating V1 cortical activity is not clear. Here, the authors demonstrate the functional role of SC in modulating V1 responses through an excitatory pathway via the dorsal lateral geniculate nucleus.

The sifting of visual information in the superior colliculus
eLife, 2020 Much of the early visual system is devoted to sifting the visual scene for the few bits of behaviorally relevant information. In the visual cortex of mammals, a hierarchical system of brain areas leads eventually to the selective encoding of important ...

Superior sensation: superior colliculus participation in rat vibrissa system [PDF]
BMC Neuroscience, 2007 Background The superior colliculus, usually considered a visuomotor structure, is anatomically positioned to perform sensorimotor transformations in other modalities.

Whisker-related afferents in superior colliculus.
Journal of Neurophysiology, 2016 Rodents use their whiskers to explore the environment, and the superior colliculus is part of the neural circuits that process this sensorimotor information. Cells in the intermediate layers of the superior colliculus integrate trigeminotectal afferents from trigeminal complex and corticotectal afferents from barrel cortex.

Superior colliculus and visual spatial attention. [PDF]
Annual Review of Neuroscience, 2013 The superior colliculus (SC) has long been known to be part of the network of brain areas involved in spatial attention, but recent findings have dramatically refined our understanding of its functional role. The SC both implements the motor consequences of attention and plays a crucial role in the process of target selection that precedes movement ...

Nature Communications, 2017 Models of visual attention postulate the existence of a saliency map whose function is to guide attention and gaze to the most conspicuous regions in a visual scene.

Preference-independent saliency map in the mouse superior colliculus [PDF]
Communications BiologyDetecting salient stimuli in a visual scene is crucial for animal survival, yet how the brain encodes visual saliency remains unclear. Here, using two-photon calcium imaging, we reveal a preference-independent saliency map in the superficial superior ...

Intrinsic connectivity of human superior colliculus [PDF]
Experimental Brain Research, 2005 The superior colliculus (SC) is believed to play an important role in sensorimotor integration and orienting behavior. It is classically divided into superficial layers predominantly containing visual neurons and deep layers containing multisensory and premotor neurons.

Preference for concentric orientations in the mouse superior colliculus
Nature Communications, 2015 The superior colliculus is a layered structure important for body- and gaze-orienting responses. Its superficial layer is, next to the lateral geniculate nucleus, the second major target of retinal ganglion axons and is retinotopically organized. Here we
