Effects of anoxia on neural activity in the Xenopus laevis lateral line

Abstract

S1188th Meeting: Acoustical Society of America S11 epithelium of the cochlea. The results of this exposure can be divided into two groups. One group had a small 10--30-dB TTS which recovered completely by 30 days. The cochlea had no unusual hair-cell losses. The second group of chinchillas demonstrated as much as a 90-dB TTS across a broad range of frequencies which resolved to a 40--50-dB PTS. The cochleas of these animals had nearly total losses of outer hair cells throughout the entire cochlea, with scattered small losses of inner hair cells. The traumatic potential of this longterm exposure is in contrast with the relatively innocuous effects of exposure to the same impulses for one hour. 3:15 F6. Effect of combinations of sodium salicylate and noise on the auditory thresholds of the chinchilla. C.M. WoodfordThirty-nine monaural chinchillas were used to study the interaction between sodium salicylate and various TTS-producing noise paradigms. Five animals were included in each
