Abstract
ROTATIONAL diffusion of rhodopsin in the visual receptor membrane was demonstrated recently by Brown1. A relaxation time of about τ≈20 µs was measured by Cone2 for the rotation of rhodopsin about an axis perpendicular to the plane of the membrane. This result was discussed in terms of the viscosity of the lipid matrix of the visual receptor membrane. It was concluded that the lipid matrix is “highly fluid”.
