Paper Abstract

Since 1974 when first laser Doppler measurements were performed of the velocity of stationary cytoplasmic streaming in single living cells of algae,' much work has been done to develop the technique and to show its potentials to monitor nonstationary intracellular motility.2'° The best model for such measurements and studies of the ameboid type of cell motility is plasmodium of slime mold Physarum polycephalum (Fig. 1). It exhibits very pronounced shuttle streaming of endoplasm inside visco—elastic protoplasmic strands with velocities up to 1.5 mm/sec. The endoplasm is driven by oscillating intracellular pressure gradients generated in the course of cyclic contractions and relaxations of the plasmodium.
