The deleterious effects of anemia on auditory nerve (AN) development have been well investigated; however, we have previously reported that significant functional consequences in the auditory brainstem response (ABR) can also occur as a consequence of marginal iron deficiency (ID). As the ABR has widespread clinical use, we evaluated the ability of this electrophysiological method to characteri...

ATM (Asynchronous Transfer Mode) networks make use of closed-loop rate-based feedback control in the ABR (Available Bit Rate) service in order to avoid network congestion. ABR mechanisms enable network designers to position node buffering requirements within their networks. End-user applications, such as Internet applications, benefit from the control action of ABR. ABR control attempts to main...

The purpose of this study was to revisit the two-channel, simultaneous click-evoked extratympanic electrocochleography and auditory brainstem response (ECoG/ABR) recording technique for clinical use in normal hearing participants. Recording the compound action potential (AP) of the ECoG simultaneously with ABR may be useful when Wave I of the ABR is small or diminished in patients with sensorin...

Results: ABR threshold for air and bone conduction were 66.53 ± 7.12 and 12.55 ± 6.96 dBnHL, respectively, in children with congenital EACA, as well as 25.32 ± 2.66 and 10.71 ± 4.51 dBnHL, respectively, in children with normal hearing. The two groups showed statistical difference in air-conduction ABR thresholds. Meanwhile, air–bone ABR threshold gap was greater in children with EACA than in ch...

The Available Bit Rate ABR service that is being standardized by the ATM Forum dynamically deter mines the maximum transmission rate the explicit rate of a connection A drawback of the dynamic control scheme for calculating the explicit rates is that it tries to allocate the same bandwidth to all ABR connections regardless of the application type of the connection In this study a multi level ex...

Gap detection is a commonly used measure of temporal resolution, although the mechanisms underlying gap detection are not well understood. To the extent that gap detection depends on processes within, or peripheral to, the auditory brainstem, one would predict that a measure of gap threshold based on the auditory brainstem response (ABR) would be similar to the psychophysical gap detection thre...

OBJECTIVE The goal of this study was to assess the effectiveness of auditory steady-state response (ASSR), determine the cut-off values for each frequency, and detect the best correlated frequencies when compared with the auditory brainstem response (ABR) thresholds in term babies under the age of 12 months. MATERIALS AND METHODS In total, 88 term babies with a mean age of 2.98 (1-11) months ...

BACKGROUND Antibiotic resistance (ABR) has become a major public health challenge in most parts of the world including Ghana and is a major threat to gain in bacterial disease control. The role of prescribers in the control of antibiotics is identified as crucial in developing interventions to control ABR. To guide policy recommendations on ABR, a study was carried out among prescribers to iden...
