Facial Nerve Schwannoma: The Rare/Great Mimicker of Vestibular Schwannoma/Neuroma
Indian Journal of Radiology and Imaging, 2021 Schwannomas are benign tumors arising from Schwann cells which are a protective casing of nerves, composing myelin sheath and can develop in any nerve where Schwann cells are present. Most common are vestibulocochlear nerve schwannomas.

Early diffusion evidence of retrograde transsynaptic degeneration in the human visual system [PDF]
, 2016 We investigated whether diffusion tensor imaging (DTI) indices of white matter integrity would offer early markers of retrograde transsynaptic degeneration (RTD) in the visual system after stroke Objective: We investigated whether diffusion tensor ...

The Current Situation and Development of Endoscopic Ear Surgery in China
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Endoscopic ear surgery has been widely performed in China since 2015 due to the development and rapid popularization of endoscopic technology. Due to the relative shortness of the auditory meatus, only a fixed endoscope is required in many cases, rather than a motion similar to a nasal endoscope, and uncontrollable bleeding is virtually non ...

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 ...

Spatiotemporal adaptation through corticothalamic loops: A hypothesis [PDF]
, 2000 The thalamus is the major gate to the cortex and its control over cortical responses is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic processing has been ...

Brain Pathology, EarlyView.We investigated neuropathological manifestations of hypothermia in 168 cases. Patients aged 65 years or more constituted 80% of the total cohort. Alzheimer's disease was the most common comorbidity, affecting 40% of all patients. Abstract There is a paucity of autopsy‐based studies providing detailed neuropathological characteristics of fatal ...

Amacrine cell inputs to OFF midget ganglion cells in macaque retina
The Journal of Physiology, EarlyView.Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...

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

A Neural Model of Surface Perception: Lightness, Anchoring, and Filling-in [PDF]
, 2003 This article develops a neural model of how the visual system processes natural images under variable illumination conditions to generate surface lightness percepts. Previous models have clarified how the brain can compute the relative contrast of images
