Which statement correctly characterizes regeneration in the mammalian nervous system?

#Unit 5. Developmental Biology
  1. In some instances, peripheral nerves can regenerate an axon if cut, such as when motor neurons regenerate axons to make correct connections with muscles
  2. Killed cells of the peripheral nervous system can be regenerated and will extend axons to restore connectivity with targets
  3. Cells of the brain can regenerate if damaged, but the peripheral nervous system is incapable of regeneration
  4. Fully functional regeneration in the mammalian nervous system has been shown to be possible when adult stem cell transplants are used
