Developmental Changes of Auditory Evoked Responses in Normal and Kanamycin Treated Rats
Auditory function is well developed at the time of birth in most animals, but in such animals as mice and rats, hearing is not functioning at birth and the ear is completed postnatally. In this study carried out on rats, auditory evoked cortical and brain stem responses were recorded to elucidate differences in the response to sound stimuli between early postnatal periods and the adult ages, and also to demonstrate the presence of a specially susceptible period to aminoglycosidic antibiotics at the time of initial appearance of auditory function.
