Efficient Temporal Processing of Naturalistic Sounds [PDF]

, 2008
In this study, we investigate the ability of the mammalian auditory pathway to adapt its strategy for temporal processing under natural stimulus conditions.

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 ...

GABAergic inhibition controls neural gain in inferior colliculus neurons sensitive to interaural time differences

, 2005
We investigated the role of GABAergic inhibition on the responses of inferior colliculus (IC) neurons sensitive to interaural time differences (ITDs) in anesthetized guinea pigs.

Detectability index measures of binaural masking level difference across populations of inferior colliculus neurons.

, 1997
In everyday life we continually need to detect signals against a background of interfering noise (the “cocktail party effect”): a task that is much easier to accomplish using two ears.

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

Supermultipotency and unpredictability in the developing superior colliculus. [PDF]

Trends Neurosci
A recent study by Cheung, Pauler, Koppensteiner et al. combining lineage tracing with single-cell RNA sequencing (scRNA-seq) has revealed unexpected features of the developing superior colliculus (SC). Extremely multipotent individual progenitors generate all types of SC neurons and glial cells that were found to localize in a non-predetermined pattern,

Kainate receptor function in rodent subcortical visual processing.

, 2007
Glutamate is found throughout the central nervous system and has been shown to be an important excitatory neurotransmitter in the visual system. There are two subdivisions of receptor on which this ubiquitous neurotransmitter acts, metabotropic (mGluR ...

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
