Synapse elimination to stabilize mature NMJs " KNOW this. motor neurons induce the maturation (loss of extrasynpatic receptors) of t he neurons. End result is 1:1 specifi c connectivity. Development of CNS synapses" CNS Synapses" This is an EM of central synapses. Dark = high electron dense materials. It is much easier to monitor neuromusucular junctions as opposed to specifi c s ynapses.
