Multisensory Information Facilitates Reaction Speed by Enlarging Activity Difference between Superior Colliculus Hemispheres in Rats

, 2011
Animals can make faster behavioral responses to multisensory stimuli than to unisensory stimuli. The superior colliculus (SC), which receives multiple inputs from different sensory modalities, is considered to be involved in the initiation of motor ...

Increase by visual stimuli in turnover of 5‐hydroxytryptamine in the superior colliculi of the rabbit.

The Journal of Physiology, 1976
1. Irregular light falshes were played on to one eye of dark adapted rabbits for periods of 20‐80 min. The concentration of 5‐hydroxyindol‐3‐ylacetic acid (5‐HIAA) and of 5‐hydroxytryptamine (5‐HT) were estimated in left and right superior colliculi, thalami and hippocampi. 2.

White matter volume loss drives cortical reshaping after thalamic infarcts

NeuroImage: Clinical, 2022
Objective: The integration of somatosensory, ocular motor and vestibular signals is necessary for self-location in space and goal-directed action. We aimed to detect remote changes in the cerebral cortex after thalamic infarcts to reveal the thalamo ...

The effect of ablation of frontal eye-fields and superior colliculi on visual stability and movement discrimination in rhesus monkeys.

, 1980
The neurological basis of the maintenance of a stable visual scene by means of a corollary discharge mechanism was investigated. Monkeys were trained to detect and respond to sudden rapid movement of a small spot of light in an otherwise totally dark ...

High-Field fMRI Reveals Brain Activation Patterns Underlying Saccade Execution in the Human Superior Colliculus [PDF]

, 2010
Background: The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye-and head-movements. The knowledge about the function of this structure is mainly based on single-unit recordings in animals with ...

Unilateral enucleation of adult rats does not effect the synapse-to-neuron ratio within the stratum griseum superficiale of the superior colliculi

, 1998
Ninety-day-old hooded male rats were anaesthetised with an intraperitoneal injection of a mixture of xylazine and ketamine and had their right eyes removed. Groups of non-enucleated control and enucleated rats were killed at either 150 or 390 days of age

Unilateral eye enucleation in adult rats causes neuronal loss in the contralateral superior colliculus

, 1997
Several studies have reported the morphological changes induced by unilateral enucleation during early neonatal life on the developing visual system. This study has examined cellular changes in the superior colliculi by removal of a single eye in adult ...

Neurocognitive Development of the Resolution of Selective Visuo-Spatial Attention: Functional MRI Evidence From Object Tracking

Frontiers in Psychology, 2018
Our ability to select relevant information from the environment is limited by the resolution of attention – i.e., the minimum size of the region that can be selected.

Histological and Biochemical Alterations in the Superior Colliculus and Lateral Geniculate Nucleus of Juvenile Rats Following Prenatal Exposure to Marijuana Smoke

Basic and Clinical Neuroscience, 2021
Introduction: Prenatal exposure to Marijuana (MJN) has been associated with various brain deficits. The main activity in marijuana, Δ9-Tetrahydrocannabinol (THC), crosses the placenta and affects fetal brain development. Despite this, marijuana remains a
