Whole-body prepulse inhibition protocol to test sensorymotor gating mechanisms in monkeys. [PDF]
PLoS ONE, 2014 Prepulse inhibition (PPI) is the decrease of startle reflex amplitude when a slight stimulus is previously generated. This paradigm may provide valuable information about sensorimotor gating functionality.

Effect of hypoxia on the retina and superior colliculus of neonatal pigs. [PDF]
PLoS ONE, 2017 To evaluate the effect of hypoxia on the neonatal pig retina and brain, we analysed the retinal ganglion cells (RGCs) and neurons in the superior colliculus, as well as the response of astrocytes in both these central nervous system (CNS) structures ...

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 ...

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.

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 ...

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.

The Distinct Role of the Amygdala, Superior Colliculus and Pulvinar in Processing of Central and Peripheral Snakes. [PDF]
PLoS ONE, 2015 Visual processing of ecologically relevant stimuli involves a central bias for stimuli demanding detailed processing (e.g., faces), whereas peripheral object processing is based on coarse identification.
