This transition is caused by a competitive interaction between the terminal branches of multiple axons co-innervating the same muscle fiber at the same junction. The muscle fiber seems to be the intermediary in the interaction by selectively initiating changes in the postsynaptic membrane (including loss of AchRs) at the sites occupied by one axon. The postsynaptic changes are soon followed by withdrawal of the overlying nerve terminals. The muscle seems to be able to distinguish the sites occupied by the different axons by virtue of their different activity patterns.
