What is synaptic pruning?

Synaptic pruning is a crucial developmental process that occurs in the brain, particularly during childhood and adolescence. It involves the selective elimination of synapses, which are the connections between neurons. The correct choice highlights that synaptic pruning is the process whereby synaptic connections that are actively used and strengthened are preserved, while those that are not used frequently are eliminated. This process helps refine neural networks, ensuring that the brain becomes more efficient by maintaining only the most necessary and frequently utilized connections.

Throughout development, the brain forms an abundance of synaptic connections, and as individuals experience learning and new environments, some of these connections are reinforced while others become weaker due to lack of use. This natural refining of synaptic connections is important for cognitive development and is influenced by various factors, including experiences and environmental interactions.
