I was watching Discovery channel when an advert for a show came on, and in it therr was a section where the voiceover said "No observable brain" with a picture of an MRI scan where indeed there seemed to be no brain, yet the woman who's scan it is was walking and talking and using the computer. My dad said he had heard soemthing about that on the radio a while back. This seems impossible to me. I can't seem to find anything about it online, I may just be looking in the wrong places. Has anyone heard of this?
