Understanding Plasticity in Brain Development and Learning
Synapses, crucial connections between nerve cells in the brain, are vital for information relay and form the basis of brain plasticity. Plasticity refers to the changes in synapses and circuits due to experiences, leading to learning and memory formation. Research indicates that during development, synapses are pruned based on relevance and usage, allowing room for new connections. Stabilization of synapses through experience aids in memory formation and building neural circuits.
