Long-term neuronal survival, regeneration, and transient target reconnection after optic nerve crush and mesenchymal stem cell transplantation

Stem Cell Research & Therapy, 2019
Background Retina and/or optic nerve injury may cause irreversible blindness, due to degeneration of retinal ganglion cells. We and others have previously shown that the intravitreal injection of mesenchymal stem cells (MSCs) protects injured retinal ...

Information transmission in oscillatory neural activity

, 2008
Periodic neural activity not locked to the stimulus or to motor responses is usually ignored. Here, we present new tools for modeling and quantifying the information transmission based on periodic neural activity that occurs with quasi-random phase ...

Can retinal ganglion cell dipoles seed iso-orientation domains in the visual cortex? [PDF]

, 2013
It has been argued that the emergence of roughly periodic orientation preference maps (OPMs) in the primary visual cortex (V1) of carnivores and primates can be explained by a so-called statistical connectivity model.

Case Report: MRI Diagnosis of Wilson's Disease in a 3‐Year‐Old Dalmatian

Veterinary Radiology &Ultrasound, Volume 66, Issue 5, September 2025.
ABSTRACT A 3‐year‐old Dalmatian was presented with anorexia, vomiting, and lethargy that progressed to neurological signs with a mixed hepatopathy. MRI identified bilaterally symmetric, ill‐defined hyperintensities in the thalamus, medial and lateral geniculate bodies, and red nuclei on T2‐weighted (T2W) and transverse T2W fluid‐attenuation inversion ...

Ramsay Hunt syndrome a case report and review of literature [PDF]

, 2013
This is a case report of a rather rare disorder i.e. Ramsay Hunt syndrome.  This is caused by Varicella zoster infections involving geniculate ganglion of facial nerve.  This syndrome is manifested by the presence of blebs in the external auditory canal,

Ocular changes as potential biomarkers for early diagnosis of Alzheimer's disease

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing,

Secondary post-geniculate involvement in Leber's hereditary optic neuropathy.

PLoS ONE, 2012
Leber's hereditary optic neuropathy (LHON) is characterized by retinal ganglion cell (RGC) degeneration with the preferential involvement of those forming the papillomacular bundle. The optic nerve is considered the main pathological target for LHON. Our

Modeling Reverse-Phi Motion-Selective Neurons in Cortex: Double Synaptic-Veto Mechanism [PDF]

, 2003
Reverse-phi motion is the illusory reversal of perceived direction of movement when the stimulus contrast is reversed in successive frames. Livingstone, Tsao, and Conway (2000) showed that direction-selective cells in striate cortex of the alert macaque ...

New strategies for neuroprotection in glaucoma,a disease that affects the central nervous system [PDF]

, 2016
Glaucoma is a disease where retinal ganglion cells (RGC) are specifically affected though a number of evidences endorse the hypothesis that glaucoma is a neuro-degenerative disorder of the central nervous system and suggest a possible connection between ...

Long‐term impact of white matter hyperintensities and amyloid beta on thalamic subregions in cerebral small vessel disease: A prospective cohort study

Alzheimer's &Dementia, Volume 21, Issue 8, August 2025.
Abstract INTRODUCTION Cerebral small vessel disease (CSVD) contributes to cognitive decline, yet the impact of white matter hyperintensity (WMH) distribution and plasma amyloid beta (Aβ) on thalamic subregions remains unclear. METHODS In this prospective study, 175 patients with CSVD and matched controls underwent high‐resolution magnetic resonance ...
