Involvement of the Superior Colliculus in SIDS Pathogenesis [PDF]

open access: yesBiomedicines, 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.

Detecting biological motion signals in human and monkey superior colliculus: a subcortical-cortical pathway for biological motion perception [PDF]

open access: yesNature Communications
Most 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.

Functional cell types in the mouse superior colliculus [PDF]

open access: yeseLife, 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,

Preference-independent saliency map in the mouse superior colliculus [PDF]

open access: yesCommunications Biology
Detecting 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]

open access: yesNature Communications
The visual continuity illusionĀ 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.

Stronger premicrosaccadic sensitivity enhancement for dark contrasts in the primate superior colliculus [PDF]

open access: yesScientific Reports
Microsaccades 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.

Inhibitory effects of prepulse stimuli on the electrophysiological responses to startle stimuli in the deep layers of the superior colliculus [PDF]

open access: yesFrontiers in Neuroscience
BackgroundPrepulse 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 ...

The connections of the inferior colliculus and the organization of the brainstem auditory system in the greater horseshoe bat (Rhinolophus ferrumequinum) [PDF]

open access: yes, 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 human superior colliculus: Neither necessary, nor sufficient for consciousness? [PDF]

open access: yes, 2007
Non-invasive neuroimaging in humans permits direct investigation of the potential role for mesodiencephalic structures in consciousness. Activity in the superior colliculus can be correlated with the contents of consciousness, but it can be also ...

Orientation and Contrast Tuning Properties and Temporal Flicker Fusion Characteristics of Primate Superior Colliculus Neurons

open access: yesFrontiers in Neural Circuits, 2018
The primate superior colliculus is traditionally studied from the perspectives of gaze control, target selection, and selective attention. However, this structure is also visually responsive, and it is the primary visual structure in several species ...
