Masked auditory thresholds in three species of birds, as measured by the auditory brainstem response (L).
Auditory brainstem responses (ABRs) were recorded in adult budgerigars, canaries, and zebra finches in quiet and in three levels of white noise for tone stimuli between 1 and 4 kHz. Similar to behavioral results, masked ABR thresholds increased linearly with increasing noise levels. When the three species are considered together, ABR-derived CRs were higher than behavioral CRs by 18-23 dB betwe...
متن کاملAuditory brainstem response in dolphins.
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...
متن کاملAUDITORY BRAINSTEM RESPONSES (ABR) IN HYPERBILIRUBINEMIC NEWBORNS
To evaluate the changes of ABR values in hyperbilirubinemic newborns, 85 cases with severe jaundice (total bilirubin levels over 16 mg/dL and direct bilirubin less than 2 mg/dL) were selected from those admitted to Children's Medical Center by simple sampling method. These infants had no other problem except jaundice. ABR was taken before treatment in all cases and in some (10 cases) after...
متن کاملThe Relationship between Severe Hyperbilirubinemia and Abnormal Auditory Brainstem Response in children
Abstract:Background : Hyperbilirubinemia is one of the most common cause of congenital sensory neuronal hearing loss. These patients are screened by auditory brainstem response (ABR) test at bilirubin levels higher than 1% of gestational weight. Aim: to determine whether hyperbilirubinemia less than 1% of gestational weight could induce hearing loss and abnormal auditory brainstem response (ABR...
متن کاملMouse Auditory Brainstem Response Testing.
The auditory brainstem response (ABR) test provides information about the inner ear (cochlea) and the central pathways for hearing. The ABR reflects the electrical responses of both the cochlear ganglion neurons and the nuclei of the central auditory pathway to sound stimulation (Zhou et al., 2006; Burkard et al., 2007). The ABR contains 5 identifiable wave forms, labeled as I-V. Wave I represe...
