correlation of these events with previous golgi observations and ongoing electron microscopic studies on pontine synaptogenesis suggest that the focusing or constriction of corticopontine axon terminal fields might be the result of a selective degeneration process in which the presynaptic ( corticopontine axon ) and postsynaptic ( basilar pontine neurons ) elements both play an active role .
