Effects of head blow on the development of hearing loss.
The effects of the direction and intensity of the head blow and the effects of the lapse of time after a head blow on the development of hearing loss were studied in guinea pigs. The electrical responses from the right inferior colliculus (ER) and from the left round window (CP) to acoustic stimuli were measured. The elevation in threshold of the ER in the presence of normal CP in guinea pigs after a head blow suggests that the site of the lesion is central to the cochlea.
