Abstract

The finite difference calculations of Neely [E.D. thesis, California Institute of Technology, Pasadena, CA (1977)] and the WKB solution of Steele and Taber [J. Acoust. Soc. Am. 65, 1001-1006 (1979)] generally agree, except in the "phase plateau" region, where both are irregular. In the present work, an improvement in the accuracy of the WKB procedure is gained by using a closed-form integral which gives the phase and damping functions in the short wavelength region. The present results agree qualitatively with the preceding but show a smooth variation with frequency and distance along the cochlea.

Expression of S-100 protein in the human fetal inner ear.

The expression of S-100 protein was analyzed in the human fetal inner ear using immunohistochemical methods. In the 11-week-old human fetus, the cochlea was almost negative for S-100 protein, whereas in the 14- and 15-week-old fetuses, the spiral ligament, Reissner's membrane and spiral limbus were positive for the protein. These results suggest that S-100 protein may be a reliable marker for determining functional maturation of the fetal cochlea and the inner ear. In the 11-, 14- and 15-week fetuses, the epithelial cells of the endolymphatic sac were labelled with S-100 protein. These findings demonstrate that the endolymphatic sac, spiral limbus and spiral ligament in the fetal inner ear have a high activity of S-100 protein, with this presence possibly related to fluid and ion transport of endolymph.

A spectral network model of pitch perception.

A model of pitch perception, called the spatial pitch network or SPINET model, is developed and analyzed. The model neurally instantiates ideas from the spectral pitch modeling literature and joins them to basic neural network signal processing designs to stimulate a broader range of perceptual pitch data than previous spectral models. The components of the model are interpreted as peripheral mechanical and neural processing stages, which are capable of being incorporated into a larger network architecture for separating multiple sound sources in the environment. The core of the new model transforms a spectral representation of an acoustic source into a spatial distribution of pitch strengths. The SPINET model uses a weighted "harmonic sieve" whereby the strength of activation of a given pitch depends upon a weighted sum of narrow regions around the harmonics of the nominal pitch value, and higher harmonics contribute less to a pitch than lower ones. Suitably chosen harmonic weighting functions enable computer simulations of pitch perception data involving mistuned components, shifted harmonics, and various types of continuous spectra including rippled noise. It is shown how the weighting functions produce the dominance region, how they lead to octave shifts of pitch in response to ambiguous stimuli, and how they lead to a pitch region in response to the octave-spaced Shepard tone complexes and Deutsch tritones without the use of attentional mechanisms to limit pitch choices. An on-center off-surround network in the model helps to produce noise suppression, partial masking, and edge pitch. Finally, it is shown how peripheral filtering and short-term energy measurements produce a model pitch estimate that is sensitive to certain component phase relationships.

Antidiuretic hormone (ADH) and endolymphatic hydrops.

Plasma antidiuretic hormone (p-ADH) concentrations were determined with a radioimmunoassay, using a reversed-phase C18 silica column, in 300 patients with vertigo, dizziness and/or deafness; 119 of them had a diagnosis of Menière's disease. The p-ADH level was significantly elevated in patients with Meniere's disease and others with endolymphatic hydrops, e.g. cochlear Menière's disease or delayed hydrops. By contrast, the p-ADH level was not so high in cases without the endolymphatic hydrops. The increase in the p-ADH level was closely linked to vertigo attacks, the glycerol test results and an enhanced negative summating potential (-SP) in electrocochleogram (ECochG). These results lead to the assumption that disorders of ADH-dependent hormonal control in the inner ear may constitute the possible mechanism underlying vertiginous attacks and deafness in patients with endolymphatic hydrops.
