pa vjerovatno zato sto im je mozak 10x manji od naseg lol You might think a mouse\'s brain would be of little help explaining the genetic workings of the human brain. Not only is the mouse version tiny--it weighs just 0.02 oz., compared with the 3-lb. behemoth in a human--but a mouse\'s rudimentary intelligence and cognition are correspondingly feeble. Still, despite these glaring differences, the genes responsible for building and operating both organs are 90% identical--which means that the mouse brain can be a powerful tool for unraveling the mystery of human mental disorders. http://www.time.com/time/magazine/article/0,9171,1580427,00.html
