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. WebOct 22, 2024 · The nervous system has a property called plasticity, which means that new synapses can form as we learn and strengthen as we make memories. Meanwhile, synapses that we do not use shrink or decrease in number. These changes in the brain can alter how neurons communicate.
