Define ABR Correct Answer - Auditory Brainstem Response - Measures neural response of the auditory pathway. - Synchronous activity of the auditory nerve and brainstem in response to an acoustic stimulus. Generator Sites of the ABR Correct Answer I - Distal CN VIII II - Proximal CN VIII III - Cochlear Nucleus IV - SOC V - Lateral Lemniscus 3 Factors that affect ABR Correct Answer - Noise - ME Disorders - Age/Gender Is ABR a test of hearing? Correct Answer - No, it's a test of th...

Auditory Brainstem Response Correct Answer - first published description by Jewett & Willston in 1971 - Early response, fast response, or short latency auditory evoked response - 5 major ABR waveforms represent synchronous neural activity - focuses on waves 1, 3, 5 - If this is present, hearing is good Neural Synchrony Correct Answer - Sharply peaked waveforms in the ABR represent this Wave I Neural Generator Correct Answer - Compound auditory nerve action potential - Distal cochlea...

What is AEP Correct Answer and auditory evoked potential What does ABR measure Correct Answer the series of "neuroelectric events" that represent sound traveling to the brain There is an immediate electrical response in the cochlea when Correct Answer a sound is introduced to the ear As the signal is propagated along the auditory pathway, it encounters Correct Answer a number of "relay stations" Time elapses as the signal Correct Answer travels between these relay stations on its...

False - ️️Skin electrode Impedance is best kept below 3000 ohms with no more that 1000 ohms difference between any two electrodes. True or False? can be used to stimulate an ABR response requires 5.4 N of pressure against the skull can be used with infants used to determine type of hearing loss - ️️Bone conduction (check all that apply). Select one or more: a. can be used to stimulate an ABR response b. requires 5.4 N of pressure against the skull c. can be used with inf...
