AIM To study the effects of ciliary neurotrophic factor (CNTF) on the expressions of gentamicin ototoxicity in guinea pigs. METHODS The auditory function of pigmented guinea pigs was examined using auditory brainstem response (ABR), cochlea microphonic potential (CM), and action potential of auditory nerve (AP). RESULTS In animals injected gentamicin (80 mg.kg-1.d-1, i.m.), ABR threshold be...

background and aim: omega 3 of essential fatty acids, especially in fish oil form plays an important role in structural, functional, and biological aspects in body. omega 3 deficiency can have devastating effects on the nervous system and auditory. this study aimed to evaluate auditory threshold in n-3 fatty acid-deficient rat pups following supplementation of fish oil consumption during the suc...

The recent discovery of the contribution of alpha synuclein in the auditory system prompted further investigation of its functional role. Auditory brainstem response (ABR) and gap detection testing were completed on wild-type and transgenic M83 mice to assess the role of alpha synuclein in noise-induced hearing loss and central auditory function.

The click-evoked auditory brainstem response (ABR) is widely used in clinical settings, partly due to its predictability and high test-retest consistency. More recently, the speech-evoked ABR has been used to evaluate subcortical processing of complex signals, allowing for the objective assessment of biological processes underlying auditory function and auditory processing deficits not revealed...

One of the most important applications of the Brainstem evoked response audiometry (ABR) is in the evaluation of hearing loss in children. Today the ABR is also indicated in the screening of cochleo-vestibular syndromes to detect retrocochlear lesions, to monitor patients in a coma (brain death), in monitoring the brainstem during skull base surgery, etc. Among the many BERA qualities, is its c...

The auditory brainstem response (ABR) was used to study the development of 8th nerve and auditory brainstem function in 71 unanesthetized gerbils. Initial replicable responses were observed on day 14. Six vertex-positive waves and a slow negative response (SNR) were obtained in response to a 100 dB HL (re adult threshold) click stimulus on day 20. A general pattern of development characterized ...
