leading up to the synapse formation. KNOW! Neuroﬁlaments" Ach receptors" Merged" newly formed synapses have a close
apposition of pre- and postsynaptic
membranes, referred to as a tight junction.
Within the ﬁ rst several hours, there are only
s ubtle changes in morphology to indicate that
s ynaptogenesis is underway. At ﬁ rst growth
c one loses its ﬁ lopodia and forms a punctate
