Self-tuning to the Hopf bifurcation in fluctuating systems

, 2005
The problem of self-tuning a system to the Hopf bifurcation in the presence of noise and periodic external forcing is discussed. We find that the response of the system has a non-monotonic dependence on the noise-strength, and displays an amplified ...

Insights Into Elevated Distortion Product Otoacoustic Emissions In Sickle Cell Disease: Comparisons of Hydroxyurea-treated and Non-treated Young Children [PDF]

, 2006
Distortion product otoacoustic emissions (DPOAEs) were examined in 15 normal- hearing African-American children between the ages of 6 and 14 years with homozygous sickle cell disease (SCD), who were on a regimen of hydroxyurea (HDU), a drug that reduces ...

Response level of the transient-evoked otoacoustic emissions on infants having a gastroesophageal reflux

International Archives of Otorhinolaryngology, 2011
Introduction: The transient-evoked otoacoustic emissions (TEOAE) have been the most widespread technique to perform neonatal hearing screening. Scrutinizing their measures by way of an association with other alterations that may impair the infant's ...

Sensory Systems as Cybernetic Systems that Require Awareness of Alternatives to Interact with the World: Analysis of the Brain-Receptor Loop in Norwich's Entropy Theory of Perception [PDF]

, 2009
Introduction & Objectives: Norwich’s Entropy Theory of Perception (1975 [1] -present) stands alone. It explains many firing-rate behaviors and psychophysical laws from bare theory.

Essential nonlinearities in hearing [PDF]

, 2000
Our hearing organ, the cochlea, evidently poises itself at a Hopf bifurcation to maximize tuning and amplification. We show that in this condition several effects are expected to be generic: compression of the dynamic range, infinitely shrap tuning at ...

Efferent auditory system: its effect on auditory processing

Brazilian Journal of Otorhinolaryngology, 2008
Summary: Auditory processing depends on afferent and efferent auditory pathways integrity. The efferent auditory system may be assessed in humans by two non-invasive and objective methods: acoustic reflex and otoacoustic emissions suppression.

Otoacoustic emissions in patients with hypotension

The Journal of Laryngology & Otology, 2003
The aim of this study was to investigate the relation between hypotension and slowly developing hearing impairment, using otoacoustic emissions. A group of 42 patients was examined, with diastolic blood pressure ≤60 mmHg and systolic blood pressure ≤105 mmHg.
