Involvement of the Superior Colliculus in SIDS Pathogenesis. [PDF]
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.

Characterization of primary visual cortex input to specific cell types in the superior colliculus. [PDF]
Front Neuroanat, 2023 The superior colliculus is a critical brain region involved in processing visual information. It receives visual input directly from the retina, as well as via a projection from primary visual cortex. Here we determine which cell types in the superficial

Functional cell types in the mouse superior colliculus. [PDF]
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,

Detecting biological motion signals in human and monkey superior colliculus: a subcortical-cortical pathway for biological motion perception. [PDF]
Nat CommunMost vertebrates, including humans, are highly adept at detecting and encoding biological motion, even when it is portrayed by just a few point lights attached to the head and major joints.

Stimulus edges induce orientation tuning in superior colliculus. [PDF]
Nat Commun, 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 ...

Preference-independent saliency map in the mouse superior colliculus. [PDF]
Commun BiolDetecting salient stimuli in a visual scene is crucial for animal survival, yet how the brain encodes visual saliency remains unclear. Here, using two-photon calcium imaging, we reveal a preference-independent saliency map in the superficial superior ...

Rat superior colliculus encodes the transition between static and dynamic vision modes. [PDF]
Nat CommunThe visual continuity illusion involves a shift in visual perception from static to dynamic vision modes when the stimuli arrive at high temporal frequency, and is critical for recognizing objects moving in the environment.

Inhibitory effects of prepulse stimuli on the electrophysiological responses to startle stimuli in the deep layers of the superior colliculus. [PDF]
Front NeurosciBackgroundPrepulse inhibition (PPI) is a phenomenon where a weak prepulse stimulus inhibits the startle reflex to a subsequent stronger stimulus, which can be induced by various sensory stimulus modalities such as visual, tactile, and auditory stimuli ...

Stronger premicrosaccadic sensitivity enhancement for dark contrasts in the primate superior colliculus. [PDF]
Sci RepMicrosaccades are associated with enhanced visual perception and neural sensitivity right before their onset, and this has implications for interpreting experiments involving the covert allocation of peripheral spatial attention.

Immunohistochemical localization of serotonin in the superior colliculus of porcupine (Hystrix cristata) [PDF]
QScience Connect, 2012 The distribution and localization of serotonin immunoreactive cells in the superior colliculus of the porcupine (Hystrix cristata) was studied using the peroxidase-antiperoxidase method and an antiserum against serotonin.
