just read the article "Mice with half-human brains four times smarter than their peers". I have given permission to have my body donated for scientific study, but am starting to doubt that decision if it means the possibility some of my brain cells would be injected into a rodent! I wasn't aware scientists could do studies of such a nature. It scares me, thinking that parts of the essence of me could be walking around a maze, trying to find my way to a piece of cheese! Yikes!! It's so into the unknown. Anyone else out there with thoughts on this?
