The Influence of a Memory Delay on Spatial Coding in the Superior Colliculus: Is Visual Always Visual and Motor Always Motor?

Frontiers in Neural Circuits, 2018
The memory-delay saccade task is often used to separate visual and motor responses in oculomotor structures such as the superior colliculus (SC), with the assumption that these same responses would sum with a short delay during immediate “reactive ...

Increased Resting-State Positron Emission Tomography Activity After Cochlear Implantation in Adult Deafened Cats [PDF]

Clinical and Experimental Otorhinolaryngology, 2023
Objectives. Cochlear implants are widely used for hearing rehabilitation in patients with profound sensorineural hearing loss. However, Cochlear implants have variable results, and central neural plasticity is considered to be a reason for this ...

Acquired ptosis associated with oculomotor and contralateral facial nerve synkinesis: the first reported case [PDF]

, 2017
Evidence of oculomotor nerve (ON) synkinesis is a common occurrence following both acquired and congenital III nerve palsy. It is generally accepted that aberrant regeneration is the likely aetiology of synkinesis in acquired III nerve palsy, following ...

Assesment of Superior Colliculus in Audiogenic Epilepsy-Prone Wistar Rats Using A Stereological Method

Archives of Epilepsy, 2017
Objectives:Audiogenic seizures are generated in the brainstem and involve the inferior and superior colliculi in their expression. Aim of the present study was to estimate total number of neurons in the right and left superior colliculi in genetically ...

Functional connectome of brainstem nuclei involved in autonomic, limbic, pain and sensory processing in living humans from 7 Tesla resting state fMRI

NeuroImage, 2022
Despite remarkable advances in mapping the functional connectivity of the cortex, the functional connectivity of subcortical regions is understudied in living humans.

Geometry of the superior colliculus mapping and efficient oculomotor computation [PDF]

, 2007
International audienceNumerous brain regions encode variables using spatial distribution of activity in neuronal maps. Their specific geometry is usually explained by sensory considerations only.

Superior colliculus responses to attended, unattended, and remembered saccade targets during smooth pursuit eye movements.

Frontiers in Systems Neuroscience, 2016
In realistic environments, keeping track of multiple visual targets during eye movements likely involves an interaction between vision,top-down spatial attention, memory, and self-motion information.

MR-based PET motion correction procedure for simultaneous MR-PET neuroimaging of human brain. [PDF]

PLoS ONE, 2012
Positron Emission Tomography (PET) images are prone to motion artefacts due to the long acquisition time of PET measurements. Recently, simultaneous magnetic resonance imaging (MRI) and PET have become available in the first generation of Hybrid MR-PET ...

A computerized analysis of the entire retinal ganglion cell population and its spatial distribution in adult rats [PDF]

, 2008
In adult albino (SD) and pigmented (PVG) rats the entire population of retinal ganglion cells (RGCs) was quantified and their spatial distribution analyzed using a computerized technique. RGCs were back-labelled from the optic nerves (ON) or the superior

Protracted treatment with MDMA induces heteromeric nicotinic receptor up-regulation in rat brain: an autoradiography study. [PDF]

, 2014
Previous studies indicate that 3,4-methylenedioxy-methamphetamine (MDMA, ecstasy) can induce heteromeric nicotinic acetylcholine receptor (nAChR, mainly of α4β2 subtype) up-regulation.
