Pruning is a key process shaping the brains of young children. Synaptic overproduction causes synapses to develop extremely rapidly. The pruning process refines these connections based on experience.

Webb6 mars 2011 · Our brains learn by altering the strength of connections between neurons, and by adding or deleting connections between neurons. The ability of a synapse can change with experience, providing us with memories. One way this happens—called potentiation —is through release of more neurotransmitters. Webb21 sep. 2024 · Because the brain is not using the same neuronal pathways, it begins to shut them down in a process known as “synaptic pruning”. It does this to be efficient and create new pathways that you’ll actually use. Your brain doesn’t necessarily understand which habits are positive for your life and which are not.
