Otoacoustic emissions and medial olivocochlear system: patients with tinnitus and no hearing loss [PDF]

, 2005
BACKGROUND: tinnitus. AIM: to compare the results of otoacoustic emissions for transitory stimulus (TEOAE) and the functioning of the olivocochlear medial system, in individuals with normal hearing sensibility, with and without tinnitus.

Theta–Beta/Gamma Coupling Identifies Bothersome Tinnitus Induced by Thalamocortical Dysrhythmia

Brain and Behavior, Volume 15, Issue 6, June 2025.
The thalamocortical dysrhythmia (TCD) was observed in all patients with tinnitus, as evidenced by elevated PAC in the auditory cortex. Particularly, BT patients show characteristic theta–gamma PAC attenuation in the orbitofrontal cortex. ABSTRACT Background The phantom sound of tinnitus can be an extremely debilitating condition.

Study on suppression of otoacoustic emissions: lateral domain Estudo da supressão da amplitude das emissões otoacústicas: dominância lateral

Brazilian Journal of Otorhinolaryngology, 2011
A pon stimulation by contralateral, ipsilateral or bilateral noise, the medial olivocochlear efferent tract changes the amplitude of otoacoustic emissions relative to the tested ear, reducing or removing it; this resulted in a reduction/suppression ...

Impacts of perinatal nicotine exposure on nicotinic acetylcholine receptor expression and glutamatergic synaptic transmission in the mouse auditory brainstem

The Journal of Physiology, Volume 603, Issue 9, Page 2857-2876, 1 May 2025.
Abstract figure legend Developmental nicotine exposure is known to cause a myriad of health defects including auditory processing deficits. In human and animal studies, nicotine exposure can lead to impaired auditory temporal processing and disrupted glutamate synapse development within the auditory cortex.

Loss‐of‐Function CARS1 Variants in a Patient With Microcephaly, Developmental Delay, and a Brittle Hair Phenotype

Molecular Genetics &Genomic Medicine, Volume 13, Issue 2, February 2025.
We report a patient with biallelic cysteinyl‐tRNA synthetase (CARS1) variants that presents with hepatopathy, hypothyroidism, short stature, developmental delay, microcephaly muscular hypotonia, brittle hair, and ataxia. Functional studies revealed that the identified variants cause hypomorphic and loss‐of‐function effects, expanding the allelic and ...

Individual differences in auditory brainstem response wave characteristics : relations to different aspects of peripheral hearing loss [PDF]

, 2016
Little is known about how outer hair cell loss interacts with noise-induced and age-related auditory nerve degradation (i.e., cochlear synaptopathy) to affect auditory brainstem response (ABR) wave characteristics.

The Survey of Neonates in Pomerania: Design, Recruitment and Follow‐Up of the Second Cohort, 2013–2017

Paediatric and Perinatal Epidemiology, Volume 39, Issue 2, Page 207-217, February 2025.
ABSTRACT Background The Survey of Neonates in Pomerania (SNiP) is a birth cohort study conducted in Western Pomerania, Germany. SNiP‐I recruited participants at birth between the years 2002 and 2008 (5801 inclusions). Since SNiP‐I, population sociodemographic characteristics and the prevalence of early exposures, including overweight and gestational ...

Analyzing transient-evoked otoacoustic emissions by concentration of frequency and time

, 2018
The linear part of transient evoked (TE) otoacoustic emission (OAE) is thought to be generated via coherent reflection near the characteristic place of constituent wave components.
