Ramsay Hunt syndrome and zoster laryngitis with multiple cranial nerve involvement

IDCases, 2015
Ramsay Hunt syndrome is characterized by varicella zoster virus infection affecting the geniculate ganglion of the facial nerve. It typically presents with vesicles in the external auditory canal associated with auricular pain and peripheral facial nerve

Gating Input to Visual Cortex by Feedback to LGN [PDF]

, 1998
Anatomical studies have documented massive back-projections from higher to lower visual cortices and to the lateral geniculate nucleus (LGN). The large number of synapses from these sources suggest that they should have a profound influence on the ...

The Visually Related Posterior Pretectal Nucleus in the Non-Percomorph Teleost Osteoglossum bicirrhosum Projects to the Hypothalamus [PDF]

, 1991
This study was done to elucidate the ancestral (plesiomorphic) condition for visual pathways to the hypothalamus in teleost fishes. Three patterns of pretectal organization can be discerned morphologically and histochemically in teleosts. Their taxonomic

Three and Four Courses of Radiation for Children with Recurrent Diffuse Intrinsic Pontine Glioma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Re‐irradiation (RT2) for children with diffuse intrinsic pontine glioma (DIPG) is increasingly used upon recurrence; however, limited data are available for evaluating additional courses of radiotherapy (RT) for DIPG. The purpose of this case series was to report our institutional experience in treating patients with recurrent DIPG ...

GanglionNet: Objectively Assess the Density and Distribution of Ganglion Cells With NABLA-N Network [PDF]

arXiv, 2020
Hirschsprungs disease (HD) is a birth defect which is diagnosed and managed by multiple medical specialties such as pediatric gastroenterology, surgery, radiology, and pathology. HD is characterized by absence of ganglion cells in the distal intestinal tract with a gradual normalization of ganglion cell numbers in adjacent upstream bowel, termed as the

Retinal adaptation and invariance to changes in higher-order stimulus statistics [PDF]

PLOS One 9 (2014): e85841, 2012
Adaptation in the retina is thought to optimize the encoding of natural light signals into sequences of spikes sent to the brain. However, adaptation also entails computational costs: adaptive code is intrinsically ambiguous, because output symbols cannot be trivially mapped back to the stimuli without the knowledge of the adaptive state of the ...

Characterisation of localised pigment accumulation in brains of eastern grey kangaroos (Macropus giganteus) after clinical disease due to chronic Phalaris species toxicosis

Australian Veterinary Journal, EarlyView.
A progressive tremorgenic syndrome characterised by ataxia and head nodding is well documented in sheep and cattle affected by chronic Phalaris toxicosis (CPT), and is increasingly documented in the eastern grey kangaroo {(EGK), Macropus giganteus} in southeastern Australia.

A precortical module for robust CNNs to light variations [PDF]

arXiv, 2022
We present a simple mathematical model for the mammalian low visual pathway, taking into account its key elements: retina, lateral geniculate nucleus (LGN), primary visual cortex (V1). The analogies between the cortical level of the visual system and the structure of popular CNNs, used in image classification tasks, suggests the introduction of an ...
