that it was not proliferation or death that caused it but reorganization of the cells. Muscular reconnection on the cut side could pull the arms to the cut side.

The observation was that the muscle reconnection was inhibited‚ but a percentage of them continued to undergo the process. However‚ it was also seen that an increase in concentration of cytochalasin D seemed
