Engineers investigate why the cochlea is coiled

( -- The word “cochlea” comes from the Latin for “snail shell.” While this inner ear component has a clear spiral shape, it’s currently unclear why that is. In the 1980s, scientists ...

Implantable medical devices powered by the ear itself

Deep in the inner ear of mammals is a natural battery—a chamber filled with ions that produces an electrical potential to drive neural signals. In today's issue of the journal Nature Biotechnology, a team of researchers ...

It's not over when it's over: Storing sounds in the inner ear

Research shows that vibrations in the inner ear continue even after a sound has ended, perhaps serving as a kind of mechanical memory of recent sounds. In addition to contributing to the understanding of the complex process ...

Researcher discusses electronic cochlear architecture

Researchers have developed an architecture and digital implementation of an electronic cochlea with an acoustic fovea and address event representation using field programmable gate arrays. Prof. Andreas Andreou of Johns Hopkins ...

The cochlea is the auditory portion of the inner ear. It is a spiral-shaped cavity in the bony labyrinth, making 2.5 turns around its axis, the modiolus. A core component of the cochlea is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating fluid chambers in the coiled tapered tube of the cochlea.

The name is from the Latin for snail shell, which is from the Greek κοχλίας kokhlias ("snail, screw"), from κόχλος kokhlos ("spiral shell") in reference to its coiled shape; the cochlea is coiled in most mammals, monotremes being the exceptions.
