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.

An Overview of Electrically Evoked Otoacoustic Emissions in the Mammalian Cochlea [PDF]

, 2006
Alternating currents injected into the cochlea are able to evoke outer hair cell-mediated basilar membrane motion, thus give rise to production of otoacoustic emissions.

Coupling of spontaneous emission from GaN/AlN quantum dots into silver surface plasmons [PDF]

, 2004
We have demonstrated surface-plasmon induced change in spontaneous emission rate in the ultraviolet regime at ~ 375-380 nm, using AlN/GaN quantum dots (QD). Using time-resolved and continuous-wave photoluminescence measurements, the recombination rate in AlN/GaN QD is shown to be enhanced when spontaneous emission is resonantly coupled to a metal ...

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 ...

Dynamics of Spontaneous Otoacoustic Emissions: Theory and Experiment [PDF]

Biophysical Journal, 2016
The vertebrate ear both responds to and emits sound. Sounds from the ear, known as otoacoustic emissions (OAEs), provide a means to probe the biophysics of auditory transduction and amplification. While the existence of spontaneous emissions (SOAEs) provides compelling evidence for an “active” ear, the mechanisms that produce them, and whether they ...

A novel TTC26 variant in a patient with hexadactyly, pituitary stalk interruption, hepatopathy, nephropathy, and bilateral lip‐palate cleft: A case report and expansion of the phenotype

American Journal of Medical Genetics Part A, Volume 194, Issue 5, May 2024.
Abstract Biallelic pathogenic variants in the TTC26 gene are known to cause BRENS (biliary, renal, neurological, skeletal) syndrome, an ultra‐rare autosomal recessive condition with only few patients published to date. BRENS syndrome is characterized by hexadactyly, severe neonatal cholestasis, and involvement of the brain, heart, and kidney, however ...

Prolonged Exposure of CBA/Ca Mice to Moderately Loud Noise Can Cause Cochlear Synaptopathy but Not Tinnitus or Hyperacusis as Assessed With the Acoustic Startle Reflex

Trends in Hearing, 2018
Hearing loss changes the auditory brain, sometimes maladaptively. When deprived of cochlear input, central auditory neurons become more active spontaneously and begin to respond more strongly and synchronously to better preserved sound frequencies.

Using Xenopus to discover new candidate genes involved in BOR and other congenital hearing loss syndromes

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 342, Issue 3, Page 212-240, May 2024.
Branchio‐oto‐renal syndrome (BOR), which results in hearing loss and craniofacial defects, is caused by mutations in either SIX1, SIX5, or EYA1. However, the underlying genetic cause is unknown in about 50% of patients. We used transcriptomics, proteomics, and yeast 2‐hybrid approaches in Xenopus embryos to identify new putative candidate genes of BOR.
