It might be better to think of apoptosis as another form of
plasticity, rather than something bad that needs to be mitigated.
During development, growth of new connections, plasticity, pruning of
unwanted connections and apoptosis all occur in a seemingly
coordinated manner to sculpt the eventual architecture of the nervous
