This chapter discusses the microcircuitry of the cochlea. The most significant microcircuits of the mammalian cochlea are very different from all others in the nervous system in that they are based on electro-mechanical and mechano-mechanical interactions. These are feedback systems. The sensory receptors of the cochlea are hair cells, polarized epithelial cells, whose mechano-sensitive organelles are highly organized actin-filled villi, misnamed stereocilia. In the mammal there are two distinct groups of hair cells: inner hair cells (IHCs) and outer hair cells (OHCs).
