title: Activity-dependent synaptic plasticity: insights from neuromuscular junctions.
abstract: Experience-dependent editing shapes synaptic connections throughout the developing nervous system, but the underlying cellular mechanisms remain poorly understood. A useful model synapse for addressing these mechanisms is the neuromuscular junction, the connection between spinal motor neurons and skeletal muscle fibers. Here the authors review current ideas about the role of activity in editing neuromuscular synaptic connections. A variety of new tools are being used to address some unanswered questions in vivo and in vitro. Understanding activity-dependent plasticity at developing neuromuscular synapses may reveal how neural circuits in the central nervous system are altered by experience throughout life.
