| | This condition is known as a perilymphatic fistula. | | | Studies performed over the past decade in our lab have shown that neither endolymph nor perilymph "flow" along their respective compartments in the normal cochlea. | | | In this condition a longitudinal flow will exist between the cochlear aqueduct and the site of the perforation. |

| | This model uses a correct placement of the BM in relation to the shelf (the BM was previously positioned on the inner side, incorrectly) and a "tall" cochlea (previous experiments used a squashed cochlea so that the a fluid grid size of 128 could be used in the vertical dimension. | | | The shell theory was derived working solely from the Kirchhoff-Love hypothesis, without the use of approximations or extraneous assumptions, such as the moderate bending assumption, used in all previous shell theories. | | | Disclaimer: All results presented on this page are preliminary, and subject to revision as we tune and correct the application. |

| | ScienceDaily: New Math Model Finds That The Cochlea's Spiral Shape Enhances Low Frequencies |
| | The next time someone whispers in your ear, think "cochlea." The cochlea is the marvelous structure in the inner ear that is shaped like a snail shell and transforms sounds into the nerve impulses that your brain can process and interpret. | | | Chadwick informed her that it was well established that the spiral shape did not affect the way that the cochlea functions. | | | Scientists Link Genetic Pathway To Development Of Hearing (August 19, 2005) -- New research findings detail how sensory hair cells in the ear develop unique shapes that enable the perception of sound. |

| | The human cochlea is a snail-shaped organ measuring about a cubic centimeter in the inner ear. | | | The mechanical cochlea works in the same way as its biological counterpart. | | | Researchers micro-machined the device using a technique similar to those used to make integrated circuits, which means it can be mass produced. |

| | The cochlea is a snail-shaped, fluid-filled structure in the inner ear. | | | Inside the cochlea is another structure called the organ of Corti. | | | The three bones in the ear (malleus, incus, stapes) pass these vibrations on to the cochlea. |

| | Experimental measurements of micromechanical transfer functions in the alligator lizard cochlea |
| | Our laboratory is studying micromechanics in the alligator lizard cochlea to determine the mechanical properties of cochlear structures and their interactions, and to gain a better understanding of the mechanisms underlying sharp frequency selectivity in the cochlea. | | | Many models of the cochlea predict that this tuning arises, at least in part, from the mechanical interactions of cochlear structures such as the tectorial membrane (TM), hair bundles, and reticular lamina (RL). | | | Because the cochlea vibrates at the frequency of the sound stimulus, which is much faster than video cameras can take images, a strobed light source is used to stop the apparent motion of the cochlea at any desired phase of the stimulus. |

| | For a pure tone the peak amplitude of the wave occurs at a specific location in the cochlea. | | | Cochlear tuning and sensitivity is further refined by the action of hair-cell basolateral ionic currents and controlled by the brain via the efferent system. | | | We have constructed a physical model to mimic the passive biomechancis of the cochlea which demonstrates the cochlear traveling wave and real-time spectrum analysis. |

| | The Cochlea of the Inner Ear |
| | The inner ear structure called the cochlea is a snail-shell like structure divided into three fluid-filled parts. | | | Two are canals for the transmission of pressure and in the third is the sensitive organ of Corti, which detects pressure impulses and responds with electrical impulses which travel along the auditory nerve to the brain. | | | The pressure changes in the cochlea caused by sound entering the ear travel down the fluid filled tympanic and vestibular canals which are filled with a fluid called perilymph. |

| | Profound deafness can be treated with cochlear implantation, which bypasses the hair cells to stimulate the vestibulocochlear nerve directly. | | | As a result, treatment is often surgical (eg, repair of the perforated eardrum, drainage of fluid-filled middle ear, reconstruction of the ossicular chain, removal of cerumen). | | | The fluid channels within the cochlea are stimulated by the vibrating stapes footplate through the membranous oval window at the base of the cochlea. |

| | The fact is, what is heard is an echo of the pulse in one's head. | | | Shaped like a snail's shell, the cochlea is formed from three ducts that run in parallel: the scala media, which contains sound-sensing hairs; the scala vestibuli, which runs from the oval window; and the scala tympani. | | | At the bottom of the cochlea duct is the basilar membrane with its organ of Corti and the sound-sensitive hair cells. |
