Wave 1 on BAEPs: electrical signal of CN 8 after a patient is given an auditory stimulus.
– Wave 2-5-> brainstem regions that are part of the auditory sensory pathway.
– bilateral absence of all waves > than wave 1 on BAEPs after a hypoxic ischemic injury suggest poor neurological outcome and brain death.
– Prolonged 3-5 interpeak latency or decreased wave V amplitude can be seen in patients with MS
– Acoustic neuromas-> prolonged wave 1-3 interpeak latency
