13. Behavioral, eletroacoustical and electrophysiological hearing evaluation in non progressive chronic infantile encephalopathy. / Avaliação comportamental, eletroacústica e eletrofisiológica da audição em encefalopatia crônica infantil não evolutiva.
In order to evaluate the hearing of children who have cerebral palsy disease the behavioral, eletroacoustical, electrophysiological evaluations were done in 61 people between three and six years and 11 months old, subdivided in experimental and control group. There were statistically significant differences when comparing the results obtained in both groups,

14. Suppression effect of transient evoked otoacoustic emissions in children with auditory processing disorder / "Efeito de supressão das emissões otoacústicas transientes em crianças com distúrbio de processamento auditivo"
This study concerns the suppression of transient evoked otoacoustic emissions by contralateral white noise in children with auditory processing disorder. Fifty-one children between 7 and 11 years old were assessed, being 15 children without auditory complaints (control group) and 36 with auditory processing disorder (divided in two experimental groups). The

15. Effects of salicylates and aminoglycosides on spontaneous otoacoustic emissions in the Tokay gecko
The high sensitivity and sharp frequency discrimination of hearing depend on mechanical amplification in the cochlea. To explore the basis of this active process, we examined the pharmacological sensitivity of spontaneous otoacoustic emissions (SOAEs) in a lizard, the Tokay gecko. In a quiet environment, each ear produced a complex but stable pattern of emis

16. Comparison of a hair bundle's spontaneous oscillations with its response to mechanical stimulation reveals the underlying active process
Hearing relies on active filtering to achieve exquisite sensitivity and sharp frequency selectivity. In a quiet environment, the ears of many vertebrates become unstable and emit one to several tones. These spontaneous otoacoustic emissions, the most striking manifestation of the inner ear's active process, must result from self-sustained mechanical osc

17. A masculinizing effect on the auditory systems of human females having male co-twins.
Spontaneous otoacoustic emissions (SOAEs) are continuous, essentially tonal sounds that are produced by many normal-hearing cochleas. In humans, females generally exhibit more SOAEs than males, a sex difference that exists from birth. However, it is shown here that females having male co-twins [opposite-sex dizygotic (OSDZ) females] exhibit about half the av

18. Active hair-bundle movements can amplify a hair cell’s response to oscillatory mechanical stimuli
To enhance their mechanical sensitivity and frequency selectivity, hair cells amplify the mechanical stimuli to which they respond. Although cell-body contractions of outer hair cells are thought to mediate the active process in the mammalian cochlea, vertebrates without outer hair cells display highly sensitive, sharply tuned hearing and spontaneous otoacou
