Electrocochleographic Changes Predict an Early Sign of Cochlear Degeneration

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 1, Page 89-100, February 2026.
ABSTRACT Objectives The purpose of this study is to identify the earliest appearing auditory electrophysiological indicators that change with age progression in young adults with normal hearing, and to analyze the frequency distribution patterns of these markers in the cochlear.

Distortion product otoacoustic emissions: challenging existing theory

, 2010
Distortion product otoacoustic emissions (DPOAE or DP) are generated using two primary tones at frequencies f1 and f2 at levels L1 and L2; the two most prominent DP are cubic distortion products at the frequencies 2f1f2 and 2f2f1.

Altered Auditory Maturation in Fragile X Syndrome and Its Involvement in Audiogenic Seizure Susceptibility

Autism Research, Volume 19, Issue 1, January 2026.
ABSTRACT Auditory hypersensitivity is a prominent symptom in Fragile X syndrome (FXS), the most prevalent monogenic cause of autism and intellectual disability. FXS arises through the loss of the protein encoded by the FMR1 (Fragile X Messenger Ribonucleoprotein 1) gene, FMRP, required for normal neural circuit excitability.

SUFU Loss‐of‐Function Heterozygous Variants Cause a Distinct Neurodevelopmental Delay With Simultaneous Effects on Brain Size

Human Mutation, Volume 2026, Issue 1, 2026.
Heterozygous loss‐of‐function variants in SUFU are associated with Gorlin syndrome (MIM:620343) and tumor predisposition, while biallelic missense variants underlie recessive Joubert syndrome (JS; MIM:617757). Interestingly, emerging evidence suggests that SUFU haploinsufficiency also contributes to neurodevelopmental disorders (NDDs).

Prolonged Exposure of CBA/Ca Mice to Moderately Loud Noise Can Cause Cochlear Synaptopathy but Not Tinnitus or Hyperacusis as Assessed With the Acoustic Startle Reflex

Trends in Hearing, 2018
Hearing loss changes the auditory brain, sometimes maladaptively. When deprived of cochlear input, central auditory neurons become more active spontaneously and begin to respond more strongly and synchronously to better preserved sound frequencies.

Revealing Pathological Auditory Central Inhibition in Tinnitus Using Cortical Auditory Evoked Potentials Responses to Contralateral Acoustic Stimulation

Brain and Behavior, Volume 15, Issue 11, November 2025.
Chronic tinnitus shows weakened contralateral suppression of cortical auditory evoked potentials, pointing to deficient central inhibition. Personalized masking therapy partially restores this inhibition, and the recovery of contralateral‐suppressed P300 amplitude closely tracks symptom relief—highlighting P300 CS as a biomarker for diagnosis and ...
