On the mechanism of action of muscle fibre activity in synapse competition and elimination at the mammalian neuromuscular junction.

Abstract excerpt

Activity-dependent competition plays a crucial role in the refinement of synaptic connections in the peripheral and central nervous system. The reduction in number of axons innervating each neuromuscular junction during development, i.e. synapse elimination, appears to be one such competitive activity-driven event. Recently, we showed that asynchronous firing of competing presynaptic terminals is a key player in...
