Neonatal auditory brainstem response thresholds to air- and bone-conducted clicks: 0 to 96 hours postpartum.
Auditory brainstem response (ABR) thresholds to air- and bone-conducted clicks were investigated in 40 full-term neonates. Subjects were divided into two groups of 20 according to postpartum age: less than 48 hours and between 49 and 96 hours. Mean ABR thresholds to air- and bone-conducted clicks for neonates less than 48 hours postpartum were 14.5 dB nHL (51.5 dB peak SPL) and 1.8 dB nHL (36.8...
متن کاملFrequency-specific auditory brainstem responses to bone-conducted stimuli.
The feasibility of recording bone-conducted auditory brainstem responses (ABRs) to 500-Hz and 2000-Hz tone bursts and clicks was investigated in normal-hearing adults. For all 3 stimuli, responses were detectable in all subjects at 30 dB nHL. At 20 dB nHL, the tone burst responses were detectable in 80-87% of the subjects, demonstrating that even the responses to 500-Hz tone bursts were relativ...
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 کاملEffects of rise-time of stimulus on auditory N1m to air-conducted, bone-conducted audible and bone-conducted ultrasonic sounds
condition elicited smaller N1m amplitude than the incongruent condition. In both hemispheres, the stepwise multiple regression revealed that the reduction rate of N1m amplitudes between the presented conditions correlated significantly with the source activities in motor and superior temporal areas. The present study suggested that some sensorimotor mediated prediction modulated auditory activi...
متن کاملAuditory brainstem responses to clicks and tone bursts in C57 BL/6J mice
In auditory research, hearing function of mouse mutants is assessed in vivo by evoked potential recording. Evaluation of the response parameters should be performed with reference to the evoked responses recorded from wild-type mice. This study reports normative data calculated on auditory brainstem responses (ABRs) obtained from 20 wild-type C57 BL/6J mice at a postnatal age between 21 and 45 ...
