I chose this site for multiple reasons. This site listed an author and it also showed a bibliography with many sources. The author of the source has a doctorate in neurophysiology. He is the chairman of medical informatics and adjunct professor at the Faculty of Medical Sciences of the State University of Campinas, in Campinas, Brazil; associate editor and chairman of the editorial board of "Brain & Mind" Magazine. The author gives an email address where one could contact him. The article is obviously well researched and is written by an author who has vast experience in this field of science. The author also shows sites where you can go to find more information. The article is not written to advertise or sell any product. The author is only putting the information out there to inform other people about the differences between male and female brains. This is why i chose this site.
