Abstract
ELECTRIC potentials generated by the inner ear in response to sound stimulation were first recorded 40 yr ago1. Studies of these extracellular potentials have led to hypotheses about the role of intracellular potentials in sensory transduction in receptor (hair) cells2,3. It is difficult, however, to infer these intracellular potentials from extracellular measurements alone4–7; measurements of intracellular potentials from hair cells are clearly desirable. Although intracellular potentials in other hair-cell receptors have been reported recently8,9, the few previous attempts to record such potentials in the cochlea have not yielded significant results10. We report here intracellular responses from single hair cells and supporting cells in the cochlea of the alligator lizard Gerrhonotus multicarinatus.
