Sound pressure fluctuations striking the ear are conveyed to the cochlea, where they vibrate
the basilar membrane on which sit hair cells, the mechanoreceptors of the inner ear …

All acoustic information from the periphery is encoded in the timing and rates of spikes in the
population of spiral ganglion neurons projecting to the central auditory system …

Aging listeners, even in the absence of overt hearing loss measured as changes in hearing
thresholds, often experience impairments processing temporally complex sounds such as …

The spiking activity of auditory nerve fibers (ANFs) transmits information about the acoustic
environment from the cochlea to the central auditory system. Increasing age leads to …

The cochlea maps tones with different frequencies to distinct anatomical locations. For
instance, a faint 5000-hertz tone produces brisk responses at a place approximately 8 …

Almost all patients who receive cochlear implants have some acoustic hearing prior to
surgery. Electrocochleography (ECoG), or electrophysiological measures of cochlear …

Introduction Understanding speech in a noisy environment, as opposed to speech in quiet,
becomes increasingly more difficult with increasing age. Using the quiet-aged gerbil, we …

Human speech primarily contains low frequencies. It is well established that such
frequencies maximally excite the cochlea near its apex. But, the micromechanics that …

Electrocochleography (ECochG) is a potential clinically valuable technique for predicting
speech perception outcomes in cochlear implant (CI) recipients, among other uses. Current …

The trapezoid body (TB) contains axons of neurons residing in the anteroventral cochlear
nucleus (AVCN) that provide excitatory and inhibitory inputs to the main monaural and …
