Role of astrocytes in the repair of auditory synapses in the cochlear nucleus after noise damage

open access: yesShanghai Jiaotong Daxue xuebao. Yixue ban
Objective·To investigate the pathological and physiological changes underlying noise-induced cochlear nucleus damage and the regulating function of astrocytes on the damage, using a combination of morphological analysis, and molecular biology techniques ...

Proximal Planar Cech Nerves. An Approach to Approximating the Shapes of Irregular, Finite, Bounded Planar Regions [PDF]

open access: yesarXiv, 2017
This article introduces proximal Cech nerves and Cech complexes, restricted to finite, bounded regions $K$ of the Euclidean plane. A Cech nerve is a collection of intersecting balls. A Cech complex is a collection of nerves that cover $K$. Cech nerves are proximal, provided the nerves are close to each other, either spatially or descriptively.

A case of cochlear-facial dehiscence revealed after bilateral cochlear implants

open access: yesRadiology Case Reports
The cochlear implant is an implanted auditory prosthesis that can restore severe and profound hearing loss. About 20% of patients with congenital sensorineural hearing loss have a malformation of the inner ear.

Stochastic Models for Cochlear Instabilities [PDF]

open access: yesarXiv, 2018
We investigate instabilities in a stochastic mathematical model of cochlear dynamics. The cochlea is modeled as a spatio-temporal dynamical system made up of a spatially distributed array of coupled oscillators, together with the cochlear amplification mechanism.

Light‐Activated Pharmacological Tools for Exploring the Cholinergic System

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Cholinergic transmission plays a critical role in both the central and peripheral nervous systems, affecting processes such as learning, memory, and inflammation. Conventional cholinergic drugs generally suffer from poor selectivity and temporal precision, leading to undesired effects and limited therapeutic efficacy. Photopharmacology aims to

Contribution of Coincidence Detection to Speech Segregation in Noisy Environments [PDF]

open access: yesarXiv
This study introduces a biologically-inspired model designed to examine the role of coincidence detection cells in speech segregation tasks. The model consists of three stages: a time-domain cochlear model that generates instantaneous rates of auditory nerve fibers, coincidence detection cells that amplify neural activity synchronously with speech ...

Proximal Nerve Complexes. A Computational Topology Approach [PDF]

open access: yesarXiv, 2017
This article introduces a theory of proximal nerve complexes and nerve spokes, restricted to the triangulation of finite regions in the Euclidean plane. A nerve complex is a collection of filled triangles with a common vertex, covering a finite region of the plane. Structures called $k$-spokes, $k\geq 1$, are a natural extension of nerve complexes.
