An intrinsic frequency limit to the cochlear amplifier
Article Abstract:
The cochlear amplifier in the inner ear determines hearing in mammals. The amplifier consists of senorimotor cells, outer hair cells, which change the passive mechanics of the cochlea. It is thought that the molecular basis of the mechanism is a voltage-sensitive motor protein. The limiting frequency at which the motor operates is shown to lie near 25 kHz, setting an upper limited to the hearing range in mammalian cochleas.

A fantasia on Kolliker's organ
Article Abstract:
The sense organs are shown to develop various afferent nerves that connect the organ to the central nervous system. An analysis also shows that the cells of a transient structure known as Kolliker's organ can also generate their own virtual music for the purpose.

The origin of spontaneous activity in the developing auditory system
Article Abstract:
The origin and importance of spontaneous activity in developing auditory system for neuronal survival of the brain are explained. The results confirm that peripheral, non-sensory cells are essential for the maturation of auditory pathways in the brain.
