The ability for the body or brain to adapt to changes caused by trauma, damage, or illness like being able to re-wire itself is known as

Neuroplasticity  provide  provide us  with   a  brain  that  is  able  to  adopt   not  only  to  the  change  inflicted  by  the  damage  but  also  it  allows  adaption  of  any  and  experience  that  might  be  encountered. The  neuron  that  fires  together  they  fires  also  together.

This ability of the brain is known as neuroplasticity or brain plasticity. It is a term that refers to the brain's ability to change throughout life.
In the 1960s, it was confirmed that the brain can rewire itself either due to learning and experience or due to injury or damage, even during adulthood. This theory came to correct the previous view of a static and unchanged adult human brain. Therefore, there is data supporting the idea that the adult brain has the ability of neurogenesis and can in some cases heal itself.
