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...

4 CSA News June 2014 related to ABR, from the development of superbugs like methicillin-resistant Staphylococcus aureus (MRSA) to speculation about the overuse of biocides like triclosan in hand soaps. A report published in 2000 by the World Health Organization (WHO) identified ABR as one of the most critical human health challenges of the 21st century. The report observed that more than two mi...

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...

We recorded the auditory brainstem response (ABR) in four dolphins (Tursiops truncatus and Delphinus delphis). The ABR evoked by clicks consists of seven waves within 10 msec; two waves often contain dual peaks. The main waves can be identified with those of humans and laboratory mammals; in spite of a much longer path, the latencies of the peaks are almost identical to those of the rat. The do...

In this paper we consider a single Asynchronous Transfer Mode (ATM) transmission link, to which Constant Bit Rote (CBR) or Variable Bit Rate (VBR) and Available Bit Rate (ABR) or UnspeciJied Bit Rate (UBR) calls arrive according to independent Poisson processes. CBR/VBR calls (characterized by their equivalent bandwidth) are blocked and leave the system if the availablelink capacity is less tha...

This paper discusses some issues and possibilities for more eeective ABR (Available Bit Rate) traac management which arise from a careful consideration of various time scales present in an ATM networking environment. Since the ABR applications will typically use the remaining resources after CBR (Constant Bit Rate) and VBR (Variable Bit Rate) applications have been accommodated, the ABR rate sh...

PURPOSE The aim of this study is to rigorously evaluate the role of auditory brainstem response (ABR) testing in the diagnosis of vestibular schwannomas (VS). MATERIALS AND METHODS Searches were conducted in multiple online databases, supplemented by hand searches. From the studies chosen for final inclusion, relevant data were extracted and meta-analysis of pooled data was performed. RESUL...

AbstructABR service relies on a feedback from the network, therefore i t strongly suffers from the long propagation delays characterizing satellite networks. In fact, i t has been shown that the high delay, in combination with high bandwidth, can deceive ABR sources and make them falsely believe that a break occurred somewhere in the path. Since ABR sources respond to breaks by reducing their c...
