[Molecular mechanisms of receptor-potential generation by the photoreceptor. I. Photic induction of a change in the permeability of artificial lipid membranes modified by photoreceptor membrane fragments].
Artificial lipid membranes modified by ultrasonic fragments of rod outer segments increase their conduction in response to illumination. Conduction increase is followed by the spontaneous foll in the dark to the unitial or somewhat higher level. The time constant of conduction increase was about 30 msec at room temperature, the constant of its following drop was about 300 msec; the activation energy of the last process was 19 +/- 3 kcal/mole.
