The fluid-filled inner-ear structure whose graded mechanics and sensory cells transform sound-driven vibration into neural signals. Distributed frequency selectivity, active feedback and temporal coding contribute distinct information; a cochlear place response alone does not identify the physical source of a sound.
The cochlea is a spiral-shaped, fluid-filled structure located in the inner ear that plays a crucial role in the process of hearing. It is named after its distinctive coiled shape, resembling a snail shell. The cochlea contains hair cells, which are sensory receptors that convert sound vibrations into electrical signals. These signals are then transmitted to the brain via the auditory nerve. The cochlea is divided into three main chambers: the scala vestibuli, scala media, and scala tympani.
