Abstract
The modulation of the transmembrane voltage of receptor cells using mechanical stimuli is an essential component of touch and hearing senses. Such stimuli influence the conducting state of mechano-sensitive channels, which in turn adjusts the ionic permeation and consequently the transmembrane voltage. The necessity of ion channels in these transduction processes seems obvious due to the non-conductive nature of a lipid membrane. However, our electrophysiology experiments show that a bare, artificial lipid membrane exposed to mechanical stress allows the passage of inorganic ions. We concluded that lipid membranes may constitute an important component of the transduction mechanism under mechanical stimuli.
