Contemporary neuro-science clearly demonstrates that 'content loading' of the human brain i. e. Learning, experience, repetitive behavior or thought, can change specific physical brain structures. (enlarge or shrink) As a shortcut Dr. Milton calls such changes 'nodules'. He goes on to ask and answer the question: Do such 'nodulized; or modified brains have the capacity to change 'thought direction' without considerable amounts of new 'content loading'. (e. g. Rehab) If peers, parents and mentors are repeating the same spiel or indoctrination, Dr Milton says, ""It is unlikely that the individual would be able to entertain or even 'see' an another point of view because of physical changes in his or her brain tissue."" Free will, Positive thinking, Evolution, Immigration and Addiction are just a few of the timely topics covered in Your Pollyanna Brain. | Your Flexxible Brain Neuro-nastics Building A Bigger Better Brain by Robert Milton, Hardcover | Indigo Chapters
