OBJECTIVES We evaluated the central auditory pathways in workers with noise-induced tinnitus with normal hearing thresholds, compared the auditory brainstem response results in groups with and without tinnitus and correlated the tinnitus location to the auditory brainstem response findings in individuals with a history of occupational noise exposure. METHOD Sixty individuals participated in t...

healthy newborns due to its lower false-positive and referral rates, high specificity, and also its’ ability to diagnose auditory neuropathy spectrum disorder combination with Transient Evoked Otoacoustic Emissions test. On the other hand, the test time can be a disadvantage. With technological advancements, a new generation Automated Auditory Brainstem Response has been developed which is fast...

REVIEW Auditory neuropathy is a disorder characterised by preservation of outer hair cell function, with normal otoacoustic emissions and/or cochlear microphonics, but an absent or distorted auditory brainstem response. PURPOSE This study aimed to objectively assess hearing thresholds in patients with auditory neuropathy, using the auditory steady state response. MATERIALS AND METHODS Thirt...

Low threshold Ca2+ currents mediated by T-type channels underlie burst spike activities of relay neurons in the thalamus. We have previously reported that knock-out mice for T-type channels show an enhanced nociceptive response to visceral pain, accompanied by an increase in tonic spikes in the absence of burst spikes in thalamic relay neurons. These results raised a possibility that T-type cha...

UNLABELLED The differential diagnosis of hearing loss with air and bone Auditory Brainstem Response in small children has not been enough studied in Brazil. AIM To compare air and bone Auditory Brainstem Response results in children under 2 months of age with normal hearing. STUDY DESIGN clinical with transversal cohort. MATERIALS AND METHODS 12 children who passed the hearing screening w...
