Non-Stationarity in Multisensory Neurons in the Superior Colliculus

Frontiers in Psychology, 2011
The superior colliculus (SC) integrates information from multiple sensory modalities to facilitate the detection and localization of salient events. The efficacy of multisensory integration is traditionally measured by comparing the magnitude of the ...

Population Coding of Interaural Time Differences in Gerbils and Barn Owls [PDF]

, 2010
Interaural time differences (ITDs) are the primary cue for the localization of low-frequency sound sources in the azimuthal plane. For decades, it was assumed that the coding of ITDs in the mammalian brain was similar to that in the avian brain, where ...

Effective connectivity in subcortical visual structures in de novo Patients with Parkinson’s Disease

NeuroImage: Clinical, 2022
Background: Parkinson’s disease (PD) manifests with the appearance of non-motor symptoms before motor symptoms onset. Among these, dysfunctioning visual structures have recently been reported to occur at early disease stages.

Functional cell types in the mouse superior colliculus

eLife, 2023
The superior colliculus (SC) represents a major visual processing station in the mammalian brain that receives input from many types of retinal ganglion cells (RGCs). How many parallel channels exist in the SC, and what information does each encode? Here,

Stimulus edges induce orientation tuning in superior colliculus

Nature Communications, 2023
Orientation columns exist in the primary visual cortex (V1) of cat and primates but not mouse. Intriguingly, some recent studies reported the presence of orientation and direction columns in the mouse superficial superior colliculus (sSC), while others ...

Multisensory Information Facilitates Reaction Speed by Enlarging Activity Difference between Superior Colliculus Hemispheres in Rats

, 2011
Animals can make faster behavioral responses to multisensory stimuli than to unisensory stimuli. The superior colliculus (SC), which receives multiple inputs from different sensory modalities, is considered to be involved in the initiation of motor ...

Prenatal VPA exposure and changes in sensory processing by the superior colliculus

Frontiers in Integrative Neuroscience, 2011
Disorders involving dysfunctional sensory processing are characterized by an inability to filter sensory information, particularly simultaneously arriving multimodal inputs. We examined the effects of prenatal exposure to valproic acid (VPA), a teratogen

Neural delays shape selectivity to interaural intensity differences in the lateral superior olive [PDF]

, 1996
Neurons in the lateral superior olive (LSO) respond selectively to interaural intensity differences (IIDs), one of the chief cues used to localize sounds in space.

Superior Colliculus: A Vision for Orienting [PDF]

Current Biology, 2018
The superior colliculus contains neurons sensitive to motion direction. New research shows that these neurons are anatomically clustered: those representing the region of visual space 'seen' by both eyes preferentially respond to nasal motion directions and others to opposite directions.

Superior sensation: superior colliculus participation in rat vibrissa system

BMC Neuroscience, 2007
Background The superior colliculus, usually considered a visuomotor structure, is anatomically positioned to perform sensorimotor transformations in other modalities.
