Visual Functions of the Primate Superior Colliculus
Annual Review of Vision Science, 2023 The superior colliculus (SC) is a subcortical brain structure that is relevant for sensation, cognition, and action. In nonhuman primates, a rich history of studies has provided unprecedented detail about this structure's role in controlling orienting behaviors; as a result, the primate SC has become primarily regarded as a motor control structure ...

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.

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 ...

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 ...

Involvement of the Superior Colliculus in SIDS Pathogenesis
Biomedicines, 2023 The aim of this study was to investigate the involvement of the mesencephalic superior colliculus (SC) in the pathogenetic mechanism of SIDS, a syndrome frequently ascribed to arousal failure from sleep.

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
