Abstract excerpt

The purine nucleotide GTP, when added extracellularly, induces oscillations in the swimming behaviour of the protist Paramecium tetraurelia. For periods as long as 10 min the cell swims backwards and forwards repetitively. The oscillations in swimming behaviour are driven by changes in membrane p...
