Reorganization of auditory cortex after neonatal high frequency cochlear hearing loss.

abstract：:Temperature sensitive auditory neuropathy is a very rare and puzzling disorder. In the present study, we reported three unrelated 2 to 6 year-old children who were diagnosed as auditory neuropathy patients who complained of severe hearing loss when they had fever. Their hearing thresholds varied from the morning to th...

abstract：:The ear of the goldfish (Carassius auratus) contains three otolithic endorgans: the saccule, lagena, and utricle. The saccule has an auditory function in most teleost fishes for whom data are available, and there is evidence that the lagena is also an auditory endorgan in the goldfish. This study was conducted to comp...
