Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

open access: yes, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

Tick on the tympanic membrane

open access: yesMedicinski pregled, 2014
Introduction. Different foreign bodies can reach the lumen of the external auditory canal. Clinical presence of the foreign bodies depends on the nature of the foreign body, localization, morphological features, and the presence of pathological process. Case Report.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Hearing in the Juvenile Green Sea Turtle (Chelonia mydas): A Comparison of Underwater and Aerial Hearing Using Auditory Evoked Potentials [PDF]

open access: yes, 2016
Sea turtles spend much of their life in aquatic environments, but critical portions of their life cycle, such as nesting and hatching, occur in terrestrial environments, suggesting that it may be important for them to detect sounds in both air and water.

Energy localisation and frequency analysis in the locust ear [PDF]

open access: yes, 2013
Animal ears are exquisitely adapted to capture sound energy and perform signal analysis. Studying the ear of the locust, we show how frequency signal analysis can be performed solely by using the structural features of the tympanum.

The endocannabinoid/cannabinoid receptor 2 system protects against cisplatin-induced hearing loss [PDF]

open access: yes, 2018
Previous studies have demonstrated the presence of cannabinoid 2 receptor (CB2R) in the rat cochlea which was induced by cisplatin. In an organ of Corti-derived cell culture model, it was also shown that an agonist of the CB2R protected these cells ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Endoscopic evaluation of tympanic isthmus patency and its effect on success rate of myringoplasty in tubotympanic type of chronic suppurative otitis media

open access: yesThe Egyptian Journal of Otolaryngology
Background Chronic suppurative otitis media (CSOM) involves persistent middle ear inflammation, often leading to tympanic membrane perforation and hearing loss. Tympanic isthmus patency is key to middle ear ventilation, influencing tympanoplasty outcomes.

Doppler optical coherence tomography as a promising tool for detecting fluid in the human middle ear

open access: yesCurrent Directions in Biomedical Engineering, 2016
The treatment of otitis media requires classifying the effusion in the tympanic cavity for choosing appropriate therapeutic strategies. Otoscopic examination of the middle ear depends on the expertise of the physician and is often hampered in case of ...

Cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission

open access: yes, 2014
A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and induces a pressure difference across the membrane.
