Statistical shape modeling of the human inner ear through micro‐computed tomography imaging

The Anatomical Record, EarlyView.
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Relating the variability of tone-burst otoacoustic emission and auditory brainstem response latencies to the underlying cochlear mechanics [PDF]

, 2015
Forward and reverse cochlear latency and its relation to the frequency tuning of the auditory filters can be assessed using tone bursts (TBs). Otoacoustic emissions (TBOAEs) estimate the cochlear roundtrip time, while auditory brainstem responses (ABRs ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Electrophysiological Evaluation of the Auditory Nerve in Normal Hearing Patients with Absence of Stapedial Reflex

International Archives of Otorhinolaryngology, 2009
Introduction: The stapedial reflex is a stapedial muscle contraction located in the middle ear, induced by an intense acoustic stimulus. It is expected that individuals with auditory thresholds within the normality standards have stapedial reflexes once ...

Cellular and synaptic specializations for sub-millisecond precision in the mammalian auditory brainstem

Frontiers in Cellular Neuroscience
Audition in all animals relies on delicate sound pressure variations arriving at the ears, and these sound waves are intertwined representations of the complex auditory environment.

Modelling the influence of short term depression in vesicle release and stochastic calcium channel gating on auditory nerve spontaneous firing statistics

Frontiers in Computational Neuroscience, 2014
We propose several modifications to an existing computational model of stochastic vesicle release in inner hair cell ribbon synapses, with the aim of producing simulated auditory nerve fibre spiking data that more closely matches empirical data ...

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Visual Hypersensitivity as a Transdiagnostic Marker of Surgical Pain Response in Arthritis and Chronic Pain Syndromes

Arthritis &Rheumatology, EarlyView.
Objective Nociplastic pain is pain primarily driven by the central nervous system and, unlike nociceptive pain conditions, is thought to be refractory to peripherally directed therapies. Nociplastic pain is also associated with hypersensitivity to painful and other sensory stimuli (such as visual stimuli). Nonpainful sensory measures have not been well

A case of auditory neuropathy revealed by OTOF gene mutation analysis in a junior high school girl

Journal of Otology, 2017
Objective: Congenital auditory neuropathy (AN) affects hearing and speech development. The degree of hearing difficulty in congenital AN varies as a function of pathology at the inner ear hair cell (IHC) synapses or the auditory nerve.

Game‐based learning for undergraduate consolidation: A qualitative study of how game‐based learning provides much more than knowledge acquisition

Anatomical Sciences Education, EarlyView.
Abstract Game‐based learning (GBL) is increasingly used in medical education to supplement traditional didactic learning methods. Adult learners in particular may benefit from GBL, given the autonomous and iterative nature of a well‐designed educational game.
