Traditionally the study of fish hearing is achieved either by psychophysical method (e.g., behavioral training) or invasive electrophysiological recording (e.g., microphonics, single unit recording). A non-invasive, the auditory brainstem response (ABR) recording method is developed to study fish hearing. With the use of the ABR method and the removal of gas from various gas holding structures,...

We propose an end-to-end rate-based congestion avoidance scheme for ABR traac on ATM networks using explicit rate indication to sources. The scheme uses a new congestion detection technique and an O(1) switch algorithm to provide high thoughput, low queues, fair operation, quick convergence and a small set of well understood parameters.

UNLABELLED Evidence from animal and human studies suggests that moderate acoustic exposure, causing only transient threshold elevation, can nonetheless cause "hidden hearing loss" that interferes with coding of suprathreshold sound. Such noise exposure destroys synaptic connections between cochlear hair cells and auditory nerve fibers; however, there is no clinical test of this synaptopathy in ...

Although sensory neural hearing loss stemming from hypercholesterolemia has received attention in recent years, no information is available about inner ear injuries resulting from this condition. In this study, we prepared guinea pig models at hypercholesterolemia and observed the inner ear with a transmission electron microscope, and also investigated the effect of vitamin E (Vit. E) on these ...

Infants with autism spectrum disorder (ASD) were recently found to have prolonged auditory brainstem response (ABR); however, at older ages, findings are contradictory. We compared ABR differences between participants with ASD and controls with respect to age using a meta-analysis. Data sources included MEDLINE, EMBASE, Web of Science, Google Scholar, HOLLIS, and ScienceDirect from their incept...

BACKGROUND The analysis of the Auditory Brainstem Response (ABR) is of fundamental importance to the investigation of the auditory system behaviour, though its interpretation has a subjective nature because of the manual process employed in its study and the clinical experience required for its analysis. When analysing the ABR, clinicians are often interested in the identification of ABR signal...

BACKGROUND Multiple sclerosis (MS) has numerous neurologic signs and symptoms, including hearing impairment. The reports concerning the type and severity of hearing loss in MS patients vary and little is known about an association of the disease characteristics with changes in hearing status. OBJECTIVE To find the otologic and neuro-otologic manifestations of MS with the use of routine hearin...

Population responses such as the auditory brainstem response (ABR) are commonly used for hearing screening, but the relationship between single-unit physiology and scalp-recorded population responses are not well understood. Computational models that integrate physiologically realistic models of single-unit auditory-nerve (AN), cochlear nucleus (CN) and inferior colliculus (IC) cells with model...

UNLABELLED Auditory Brainstem Response (ABR) is important for the early diagnosis of hearing impairment in infants. AIM To compare ABR responses in full-term and premature infants; gender and ear were taken into account. METHODS A cross-sectional prospective cohort study was carried out. We evaluated 36 full-term and 30 premature infants that had passed the Transient Otoacoustic Emissions t...

In rodents, exposure to high-level noise can destroy synapses between inner hair cells and auditory nerve fibers, without causing hair cell loss or permanent threshold elevation. Such "cochlear synaptopathy" is associated with amplitude reductions in wave I of the auditory brainstem response (ABR) at moderate-to-high sound levels. Similar ABR results have been reported in humans with tinnitus a...
