Hair cell receptor potentials have been examined in both mammalian inner and outer hair cells (Russell, Cody, & Richardson, 1986; Dallos, Santos-Sacchi, & Flock, 1982; Russell & Sellick, 1978) and in hair cells from vestibular and cochlear organs of non-mammalian vertebrates (Crawford & Fettiplace, 1981; Harris, Frishkopf & Flock, 1970; Hudspeth and Corey, 1977). The outer hair cell may be a special case (Russell, Cody & Richardson, 1986), but in all other hair cells intracellular recordings of the receptor potential clearly reveal the presence of an asymmetric response, characterized as having a saturating non-linearity. This receptor potential in non-mammalian hair cells was partially attributed to a rectification property of the hair cell membrane (Crawford & Fettiplace, 1981, Hudspeth & Corey, 1977). In mammalian inner hair cells the receptor potential is non-linear (Russell & Sellick, 1978) as with other hair cells, but the membrane properties appeared more linear (Russell, 1983; Russell, Cody & Richardson, 1986).
