Before revision:  We also predicted that the final position of the posterior centrosome and thus the spindle has a reduced dependence upon the force generator dynamics or number . Conclusion: The outburst of forces responsible of spindle anaphase oscillations and positioning is regulated by the spindle position through the spatial modulation of microtubule contactsat the cortex .
After revision:  We also predicted that the final position of the posterior centrosome and thus the spindle has a reduced dependence upon the force generator dynamics or number . Conclusion: The spindle position regulates the rapid increase in forces needed for anaphase oscillation and positioning through the spatial modulation of microtubule contactsat the cortex .
