The anatomic consequences of acoustic overstimulation are explored in this presentation,
and attention is directed toward issues where improvements in technology and empirical …

Located on the sensory epithelium of the sickle-shaped cochlea of a 7- to 10-d-old chick are
approximately 5,000 hair cells. When the apical surface of these cell is examined by …

Auditory evoked responses were recorded from the cochlear nuclei of chicks from D10 of
incubation to 3 weeks after hatching. Round window recordings of the cochlear microphonic …

Targeted mutagenesis in mice demonstrates that the POU-domain gene Brn4/Pou3f4 plays
a crucial role in the patterning of the mesenchymal compartment of the inner ear.Brn4 is …

Objectives/Hypothesis The purpose of this study is to compare collateral tissue damage and
wound healing in incisions created by electro‐dissociation and conventional electrosurgery. …

Tinnitus is a vexing disorder of hearing characterized by sound sensations originating in the
head without any external stimulation. The specific etiology of these sensations is uncertain …

In Exps I and II avoidance conditioning and the method of limits were used to measure
absolute auditory thresholds, masked thresholds, and critical ratios in 4 parakeets. The same …

This presentation considers important developments and new trends related to acoustic injury
in the peripheral auditory system reported during the past 5 years. The discussion begins …

The anatomic features of the chinchilla middle ear were identified and various aspects of
the conductive apparatus were measured in a number of specimens by different methods. …

The middle-ear system of all vertebrates improves the efficiency of sound transmission from
the surrounding medium, be it air, water, or ground, to the inner ear. The process by which …
