Sensory Transduction in Hair Cells

  • Å. Flock
Part of the Handbook of Sensory Physiology book series (SENSORY, volume 1)


The neural mechanism that underlies excitation and sensory processing in the inner ear is unlike that of most other mechanoreceptor-nerve preparations in that the receptor is not a part of the sensory neuron but a specialized epithelial cell which excites the sensory neuron by synaptic transmission. The peripheral excitatory processes take place in several sequential stages, and it is difficult to localize the particular stage at which various output characteristics are contributed. This is also because hair cells are used to subserve different functions in the various organs of hearing and equilibrium. It is not intended here to describe the function of separate end-organs as separate entities but to find basic principles of structure and function of hair cells and their nervous connections on a comparative basis.
