Personally, I think the truly crazy ones are the scientists that think mouse and rat brains are the same as human ones
Quoting: Rev StarGazer The fact that mice are not people is finally starting to demand attention in science: [ link to www.sciencenews.org] In the new study, a group of Canadian and American researchers compared how human and mouse genes respond to certain types of trauma. They looked at gene activity in the blood of 167 people severely injured either by burns or by blunt trauma, such as in a car accident. They compared those results with gene activity in the blood of mice with similar injuries. The team also examined the reactions to an injection of endotoxin, a bacterial toxin, of four healthy people and 16 mice.
People’s immune systems reacted in predictable ways, cranking up activity in genes that cause inflammation and quieting other immune system genes, Tompkins says. When the researchers compared the gene activity changes in people with burns versus people with trauma, they found 97 percent similarity. For injuries and endotoxin exposure, 88 percent of genes responses were similar.
But mouse responses were more varied, says study coauthor Wenzhong Xiao, a genome scientist at Harvard University and Stanford University. Compared with what goes on in humans, 47 to 63 percent of mouse genes changed activity in the same way. The result was not far from what researchers would expect from random chance
A man is not a mouse.
