Presynapse formation is a dynamic process including accumulation of synaptic proteins in proper order. In this method, presynapse formation is triggered by beads conjugated with a presynapse organizer protein on axonal sheets of “neuron ball” culture, so that accumulation of synaptic proteins is easy to be analyzed during presynapse formation.
