The idea that synapses could … WebSynapse formation is finely regulated. It involves processes at the cellular and subcellular levels, which result in: axons finding their appropriate targets from an array of choices; synapses being formed on the correct cellular compartment; and formation of pre- and postsynaptic specializations that allow for efficient information transfer.
