11,32) The difference has been attributed to the fact that the outer hair cell properties are considered to be mature at 32 weeks of gestation, (33) while it has been proposed that maturation of the medial olivocochlear efferent innervation of the outer hair cells occurs at 37 weeks.
Also included are two objective test methods for identifying outer hair cell changes and predicting audiogram changes using distortion-product otoacoustic emissions (DPOAEs).
This effect, which is probably linked to MLT's ability to reduce c-fos and TNF-alpha gene expression thereby preventing outer hair cell (OHC) loss, was even more pronounced in week 3.
While the distortion product otoacoustic emissions did not prove useful in this population for early identification of outer hair cell damage and hearing loss, the measures did match the permanent hearing threshold shifts at posttraining measurements.
Platinum compounds damage the stria vascularis (columnar epithelium with capillaries which secretes endolymph in the scala media) and cause outer hair cell death beginning at the basal turn of the cochlea.
DPOAEs are a measure of outer hair cell function in the inner ear and are another sensitive and specific measure of ototoxicity.
Furthermore, by studying mice with two, one and zero copies of the gene expressing prestin, Zuo and his colleagues have shown there is a surprisingly simple correlation between outer hair cell motility and amplification.
4) Bauer proposed that tinnitus is the result of reversible outer hair cell dysfunction and decoupling stereocilia from the tectorial membrane.
141) Salvi et al showed that leupeptin caused as much as a 60% reduction in outer hair cell loss from acoustic overstimulation (an octave-band noise centered at 4.
According to Spoendlin, three or four fibers end on each outer hair cell, but none ends directly on the inner hair cells.
When the outer hair cells become nonfunctional, the result is a reduction in hearing sensitivity, typically in the high-frequency region.
