Organization of the inputs and outputs of the mouse superior colliculus

Nature Communications, 2021
The superior colliculus (SC) receives diverse cortical inputs to drive many behaviors. Here, based on comprehensive mapping of cortico-tectal projections, the authors refined the superior colliculus into medial, centromedial, centrolateral, and lateral ...

High-density electrode recordings reveal strong and specific connections between retinal ganglion cells and midbrain neurons

Nature Communications, 2022
The superior colliculus receives visual information from retinal ganglion cells, but it remains unclear how this information is organized and integrated in vivo.

Effects of Transcranial Ultrasound Stimulation on Trigeminal Blink Reflex Excitability

Brain Sciences, 2021
Recent evidence indicates that transcranial ultrasound stimulation (TUS) modulates sensorimotor cortex excitability. However, no study has assessed possible TUS effects on the excitability of deeper brain areas, such as the brainstem.

Superior colliculus modulates cortical coding of somatosensory information

Nature Communications, 2020
While there is no direct pathway from the superior colliculus to the cortex, the authors find that the superior colliculus modulates sensory-evoked responses in the somatosensory cortex.

The mechanism of saccade motor pattern generation investigated by a large-scale spiking neuron model of the superior colliculus. [PDF]

PLoS ONE, 2013
The subcortical saccade-generating system consists of the retina, superior colliculus, cerebellum and brainstem motoneuron areas. The superior colliculus is the site of sensory-motor convergence within this basic visuomotor loop preserved throughout the ...

The human superior colliculus: Neither necessary, nor sufficient for consciousness? [PDF]

, 2007
Non-invasive neuroimaging in humans permits direct investigation of the potential role for mesodiencephalic structures in consciousness. Activity in the superior colliculus can be correlated with the contents of consciousness, but it can be also ...

The superior colliculus [PDF]

Current Biology, 2004
Considerable progress has been made in understanding the sensory and motor functions of the superior colliculus and how these interact to produce behavioral responses. The organization of the sensory and motor maps, and the close relationship between them, has rendered this midbrain structure the region of choice for addressing a number of fundamental ...

The connections of the inferior colliculus and the organization of the brainstem auditory system in the greater horseshoe bat (Rhinolophus ferrumequinum) [PDF]

, 1981
The connections of the inferior colliculus, the mammalian midbrain auditory center, were determined in the greater horseshoe bat (Rhinolophus ferrumequinum), using the horseradish peroxidase method.

Orientation and Contrast Tuning Properties and Temporal Flicker Fusion Characteristics of Primate Superior Colliculus Neurons

Frontiers in Neural Circuits, 2018
The primate superior colliculus is traditionally studied from the perspectives of gaze control, target selection, and selective attention. However, this structure is also visually responsive, and it is the primary visual structure in several species ...

Motor Functions of the Superior Colliculus [PDF]

Annual Review of Neuroscience, 2011
The mammalian superior colliculus (SC) and its nonmammalian homolog, the optic tectum, constitute a major node in processing sensory information, incorporating cognitive factors, and issuing motor commands. The resulting action—to orient toward or away from a stimulus—can be accomplished as an integrated movement across oculomotor, cephalomotor, and ...
