And yet the biological explanation for the many physical differences between males and females remains incomplete. "How it is that males and females can end up looking so different, when they have basically the same genome?" asks John Pool, an assistant professor of genetics at the University of Wisconsin—Madison. And although many significant differences can be laid to the famous Y chromosome found only in males, that's is not the whole story. In a study of  fruit flies  now online in

He also has a clinic in Naples, Florida, and he's been very active in publishing his findings in peer-reviewed medical journals. His previous book,  Grain Brain , topped the New York Times bestseller list for 54 weeks. In my view, Dr. Perlmutter is probably the leading natural medicine neurologist in the US. Certainly, most neurologists fail to consider how lifestyle impacts the neurological disorders they diagnose and treat every day, and prevention is an area of utmost importance as we still do not have effective treatments for many of the most common brain disorders.
