The peripheral nervous system was long known to be plastic; if you cut a nerve in your hand, it can “regenerate” or heal itself.

The second part is the peripheral nervous system, which brings messages from the sense receptors to the spinal cord and brain and carries messages from the brain and spinal cord to the muscles and glands.

How Neurons Communicate: Excitation and Inhibition The nervous system comprises the central nervous system and the peripheral nervous system. Neurons communicate via excitatory and inhibitory signals, with synapses facilitating this interaction. Pl…

The nervous system is divided into two parts. The first part is the central nervous system (the brain and spinal cord), which is the command-and-control center of the system; it was thought to lack plasticity.
