Nonlinear visuoauditory integration in the mouse superior colliculus.
PLoS Computational Biology, 2021 Sensory information from different modalities is processed in parallel, and then integrated in associative brain areas to improve object identification and the interpretation of sensory experiences.

Frontiers in Neural Circuits, 2021 Dopamine (DA) modulates the activity of nuclei within the ascending and descending auditory pathway. Previous studies have identified neurons and fibers in the inferior colliculus (IC) which are positively labeled for tyrosine hydroxylase (TH), a key ...

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 ...

Spatial frequency sensitivity in macaque midbrain
Nature Communications, 2018 In primates, the superior colliculus (SC) contributes to rapid visual exploration with saccades. Here the authors show that the superior colliculus preferentially represents low spatial frequencies, which are the most prevalent in natural scenes.

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 ...

Superior Colliculus Control of Vibrissa Movements [PDF]
Journal of Neurophysiology, 2008 This study tested the role of the superior colliculus in generating movements of the mystacial vibrissae—whisking. First, we compared the kinematics of whisking generated by the superior colliculus with those generated by the motor cortex. We found that in anesthetized rats, microstimulation of the colliculus evoked a sustained vibrissa protraction ...

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

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.
