On the mechanism of conductance control of the arthropod visual cell membrane.

Abstract

It is assumed that "dark channels" determine a permanent dark conductance of the arthropod visual cell membrane. The light stimulus causes a transient opening of "light channels". The ion selectivity of dark channels and light channels is roughly described. Factors influencing the activation of light channels, as membrane energy metabolism, membrane potential and adjusted calcium ion concentration are specified. The mechanism of the action of calcium ions on the conductance of the visual cell membrane is discussed.
