TL;DR: The elucidation of the transduction process is closely related to the understanding of the mechanisms by which ions cross the cell membrane, and in the last years some progress has been made in the investigation of lipid model membranes.
Abstract: One of the first steps in sensory excitation is a change in the ion permeability of a membrane. The elucidation of the transduction process is therefore closely related to our understanding of the mechanisms by which ions cross the cell membrane. As yet, most ion transport mechanisms in biological membranes are still obscure at the molecular level. On the other hand, in the last years some progress has been made in the investigation of lipid model membranes. We may expect that these studies may lead to a better insight into the possible ion transport mechanisms in the cell membrane.
