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

open access: yesPLoS 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

Fractal features of dark, maintained, and driven neural discharges in the cat visual system [PDF]

open access: yesMethods 24, 377-394 (2001), 1999
We employ a number of statistical measures to characterize neural discharge activity in cat retinal ganglion cells (RGCs) and in their target lateral geniculate nucleus (LGN) neurons under various stimulus conditions, and we develop a new measure to examine correlations in fractal activity between spike-train pairs. In the absence of stimulation (i.e.,

Surgical Approaches to Pre‐Auricular Cutaneous Squamous Cell Carcinomas Extending to the Temporal Bone

open access: yesHead &Neck, Volume 47, Issue 6, Page 1736-1748, June 2025.
ABSTRACT Background Standardized surgical approaches to advanced pre‐auricular cutaneous squamous cell carcinomas (cSCC) are lacking. Methods Fifty–four patients who underwent lateral temporal bone resection (LTBR) for pre‐auricular cSCC were grouped into “Levels” of increasing disease spread.

The power ratio and the interval map: spiking models and extracellular data [PDF]

open access: yesarXiv, 1998
We describe a new, computationally simple method for analyzing the dynamics of neuronal spike trains driven by external stimuli. The goal of our method is to test the predictions of simple spike-generating models against extracellularly recorded neuronal responses. Through a new statistic called the power ratio, we distinguish between two broad classes

Glutamatergic Regulation of miRNA‐Containing Intraluminal Vesicle Trafficking and Extracellular Vesicle Secretion From Cortical Neurons

open access: yesJournal of Extracellular Vesicles, Volume 14, Issue 6, June 2025.
ABSTRACT Neuronal extracellular vesicles (microvesicles and exosomes) are emerging secreted vesicular signals that play important roles in the CNS. Currently, little is known about how glutamatergic signalling affects the subcellular localisation of exosome precursor intraluminal vesicles (ILVs), microRNA (miR) packaging into ILVs and in vivo spreading

Varicella-zoster virus reactivation from multiple ganglia: a case report

open access: yesJournal of Medical Case Reports, 2009
Introduction Simultaneous involvements of multiple cranial nerve ganglia (geniculate ganglion and peripheral ganglia of cranial nerves VIII, IX and X) by varicella-zoster virus and its subsequent activation may result in the characteristic eruptions of ...

Strong surround antagonism in the dLGN of the awake rat [PDF]

open access: yesarXiv, 2012
Classical center-surround antagonism in the early visual system is thought to serve important functions such as enhancing edge detection and increasing sparseness. The relative strength of the center and surround determine the specific computation achieved.

Changes in the Nationwide Incidence of Bell's Palsy in the General Population Before and After the COVID‐19 Pandemic: An Ecological Study

open access: yesJournal of Medical Virology, Volume 97, Issue 6, June 2025.
ABSTRACT This nationwide population‐based ecological study investigated changes in the incidence of Bell's palsy (BP) in South Korea during the COVID‐19 pandemic. Patients diagnosed with BP between January 2017 and December 2022 were analyzed. Considering the unique progression of the COVID‐19 pandemic and corresponding public health responses in South
