The Brain does not seem to have many limits on its possibilities for growth and taking other functions based on observation of learning achieved by people with brain dammage or brain problems.

Thoughts about t
Isn't it true that the brain is an amazing organ? Some people function with only a small piece of their brain..that were in accidents or injuries.  I have had many clients with alot of seizure, lobotomies and brain damage yet they learn to do almost anything... so I think even if the research specifically has not been done the outcome of teaching people shows that the brain can develope and grow in most all areas of learning and performance.
