   Our readingNeuroplasticity is as much the removal of connections as the growth of new ones, so pruning is a form of learning rather than a form of decay.

   Their wordsA lot of people don't realize that particularly brain development, but then also the refining of functions in the brain through neuroplasticity includes the pruning or removal of signapses. Often we think about it's all about growth and new connections, but actually it also involves the refining or removal of of other connections that aren't needed.
