In tracking down articles posted to the internet, I ran across the following column at alternativescience(dot)co m titled "Is your brain really necessary?" The first three paragraphs follow:

Do you really have to have a brain? The reason for my apparently absurd question is the remarkable research conducted at the University of Sheffield by neurology professor the late Dr. John Lorber.

When Sheffield’s campus doctor was treating one of the mathematics students for a minor ailment, he noticed that the student’s head was a little larger than normal. The doctor referred the student to professor Lorber for further examination.

The student in question was academically bright, had a reported IQ of 126 and was expected to graduate. When he was examined by CAT-scan, however, Lorber discovered that he had virtually no brain at all.
