Stimulus Processing in Vestibular Hair Cells

Abstract

Mammalian vestibular organs have two types of sensory cells: type I and type II hair cells. To compare signalling properties of these cell types, we prepare isolated hair cells from which we record membrane currents in response to voltage steps. The isolated cells appear to retain their distinctive morphologies, and therefore are identifiable as either type I or type II. Preliminary results reveal that in some cells, the currents elicited by voltage steps are qualitatively similar to those previously described in frog and chick vestibular hair cells. Keywords: Vestibular transduction, Hair cells, Sensor physiology.
