Timeline of Neural Pruning
The process of neural pruning continues beyond early childhood, extending through adolescence and into adulthood in certain brain regions. This selective reduction of synapses occurs in various areas of the brain at different times, with the prefrontal cortex being one of the last to fully mature through this process.

Timeline of Neural Pruning
A developmental researcher is comparing the brain structures of two young adults who have both spent years mastering the violin. Brain Scan A shows an incredibly dense and widespread network of neural pathways in the motor cortex. Brain Scan B shows a less dense, but more organized and defined network of pathways in the same region, with fewer redundant connections. Based on the principle that brain development involves refining connections for efficiency, which of the following is the most likely analysis of this situation?
