Contribution of active hair-bundle motility to nonlinear amplification in the mammalian cochlea
Abstract The cochlea’s high sensitivity stems from the active process of outer hair cells, which possess two force-generating mechanisms: active hair-bundle motility elicited by Ca2+ influx and somatic motility mediated by the voltage-sensitive protein prestin. Although interference with prestin has demonstrated a role for somatic motility in the active process, it remains unclear whether … Read more
Simplified Model to Demonstrate the Energy Flow and Formation of Traveling Waves similar to those found in Cochlea
The hearing nerves of vertebrates have their endings on the basilar membrane. The total length of this membrane in man is 35 mm. Its width varies continuously from 0.04 to 0.5 mm., and accordingly the stiffness of the membrane decreases over its length one hundred fold. The whole membrane is imbedded in fluid, and, when … Read more
The basis of musical consonance as revealed by congenital amusia
Some combinations of musical notes sound pleasing and are termed “consonant,” but others sound unpleasant and are termed “dissonant.” The distinction between consonance and dissonance plays a central role in Western music, and its origins have posed one of the oldest and most debated problems in perception. In modern times, dissonance has been widely believed … Read more
Functional anatomy of musical processing in listeners with absolute pitch and relative pitch
Abstract We used both structural and functional brain imaging techniques to investigate the neural basis of absolute pitch (AP), a specialized skill present in some musicians. By using positron emission tomography, we measured cerebral blood flow during the presentation of musical tones to AP possessors and to control musicians without AP. Listening to musical … Read more
The Discordant Eardrum – Chaotic and Superior above 3 kHz
Abstract “At frequencies above 3 kHz, the tympanic membrane vibrates chaotically. By having many resonances, the eardrum can transmit the broadest possible bandwidth of sound with optimal sensitivity. In essence, the eardrum works best through discord. The eardrum’s success as an instrument of hearing can be directly explained through a combination of its shape, … Read more
