Synapse Elimination
Several motorneurones compete for each neuromuscular junction, but only one survives until adulthood. Competition in vitro has been shown to involve a limited neurotrophic substance that is released, or that neural activity infers advantage to strong post-synaptic connections by giving resistance to a toxin also released upon nerve stimulation. In vivo it is suggested that muscle fibres select the strongest neuron through a retrograde signal.

“The kind of Unitarian
Who having by elimination got
From many gods to Three, and Three to One,
Thinks why not taper off to none at all.”
