Click-Evoked Potentials in a Large Marine Mammal, the Adult Male Northern Elephant Seal (Mirounga angustirostris) (L)
Auditory evoked potential (AEP) hearing studies in marine mammals should consider an expected size-dependent reduction in AEP amplitude. This study is the first to measure the click-evoked response in a large marine mammal, the adult male elephant seal (Mirounga angustirostris) . Click stimuli were...

Auditory evoked potential (AEP) hearing studies in marine mammals should consider an expected size-dependent reduction in AEP amplitude.
