Efferent modulation of stimulus frequency otoacoustic emission fine structure

open access: yesFrontiers in Systems Neuroscience, 2015
Otoacoustic emissions, sounds generated in the inner ear, have become a convenient non-invasive tool to examine the efferent modulation of cochlear mechanics.

A tympanal insect ear exploits a critical oscillator for active amplification and tuning [PDF]

open access: yes, 2013
SummaryA dominant theme of acoustic communication is the partitioning of acoustic space into exclusive, species-specific niches to enable efficient information transfer.

Comparison of healing of acute total tympanic membrane perforation between rats with and without excision of the mallear handle

open access: yesLaryngoscope Investigative Otolaryngology, Volume 8, Issue 6, Page 1648-1656, December 2023., 2023
(1) The upper halves of the annulus may be the main the epithelial cell proliferation center in SD rats, the excision or preservation of the malleus handle doesn’t affect the closure of total perforation. (2) The malleus handle contributes to accelerate the perforation closure by possible guide the migration of proliferative epithelial cell.

Scientific opinion on the tolerable upper intake level for manganese

open access: yesEFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract Following a request from the European Commission (EC), the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on the tolerable upper intake level (UL) for manganese. Systematic reviews of the literature of human and animal data were conducted to assess evidence regarding excess manganese ...

Otoacoustic Emissions in Smoking and Nonsmoking Young Adults [PDF]

open access: yesClinical and Experimental Otorhinolaryngology, 2015
ObjectivesThe present study investigates the usefulness of transiently evoked otoacoustic emissions (TEOAEs) and distortion product OAEs (DPOAEs) in detecting small changes in the hearing of young smoking adults.MethodsOtoacoustic emissions were acquired

Synchronization of Spontaneous Active Motility of Hair Cell Bundles. [PDF]

open access: yesPLoS ONE, 2015
Hair cells of the inner ear exhibit an active process, believed to be crucial for achieving the sensitivity of auditory and vestibular detection. One of the manifestations of the active process is the occurrence of spontaneous hair bundle oscillations in

Waves on Reissner's membrane: a mechanism for the propagation of otoacoustic emissions from the cochlea [PDF]

open access: yesCell Reports 1, 374-384 (2012), 2012
Sound is detected and converted into electrical signals within the ear. The cochlea not only acts as a passive detector of sound, however, but can also produce tones itself. These otoacoustic emissions are a striking manifestation of the cochlea's mechanical active process.

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

open access: yes, 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 ...
