Resumen:
When Ca2+ is released from internal stores in living
cells, the resulting wave of increased concentration can travel without deformation (continuous propagation) or with burst-like behavior (saltatory propagation). We analyze the "fire-diffuse-fire"
model in order to illuminate the differences between these two modes of
propagation. We show that the Ca2+ release wave in immature
Xenopus oocytes and cardiac myocytes is saltatory, whereas
the fertilization wave in the mature oocyte is continuous.
