Visual Threat Location Impacts Brain‐Wide Visual Adaptation Networks

Journal of Comparative Neurology, Volume 534, Issue 7, July 2026.
Mancienne et al. explored the impacts of varying stimulus position on visual adaptation in zebrafish larvae. They found that responses to a looming stimulus in a particular visual position adapt quickly, but that looms elsewhere in the visual field have little impact on adaptation to the reference stimulus.

The sifting of visual information in the superior colliculus

eLife, 2020
Much of the early visual system is devoted to sifting the visual scene for the few bits of behaviorally relevant information. In the visual cortex of mammals, a hierarchical system of brain areas leads eventually to the selective encoding of important ...

Rat superior colliculus encodes the transition between static and dynamic vision modes

Nature Communications
The 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.

Stereological analysis of the vascular network in superior colliculi [PDF]

Scripta Medica, 2020
Background/Aim: Superior colliculi have an important role in the visual system, some motor functions and behaviour. Branches of the posterior cerebral artery and surrounding vessels form a collicular arterial network, which gives rise to several ...

Orientation columns in the mouse superior colliculus

Nature, 2014
More than twenty types of retinal ganglion cells conduct visual information from the eye to the rest of the brain. Each retinal ganglion cell type tessellates the retina in a regular mosaic, so that every point in visual space is processed for visual primitives such as contrast and motion.

The superior colliculus directs goal-oriented forelimb movements

Cell Reports
Summary: Skilled forelimb control is essential for daily living, yet our understanding of its neural mechanisms, although extensive, remains incomplete. Here, we present evidence that the superior colliculus (SC), a major midbrain structure, is necessary

Patterns of convergence in the central nucleus of the inferior colliculus of the Mongolian gerbil: organization of inputs from the superior olivary complex in the low frequency representation

Frontiers in Neural Circuits, 2013
Projections to the inferior colliculus from the lateral and medial superior olivary nuclei were studied in the gerbil (Meriones unguiculatus) with neuroanatomical tract-tracing methods. The terminal fields of projecting axons were labeled via anterograde

Functional modulation of primary visual cortex by the superior colliculus in the mouse

Nature Communications, 2018
The role of the superior colliculus (SC) in modulating V1 cortical activity is not clear. Here, the authors demonstrate the functional role of SC in modulating V1 responses through an excitatory pathway via the dorsal lateral geniculate nucleus.

Dbx1 is a dorsal midbrain-specific determinant of GABAergic neuron fate and regulates differentiation of the dorsal midbrain into the inferior and superior colliculi

Frontiers in Cell and Developmental Biology
The mechanism underlying the differentiation of the dorsal midbrain into two morphologically and functionally distinct compartments, the inferior colliculus (IC) and superior colliculus (SC), which process auditory and visual information, respectively ...

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

Frontiers 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 ...
