Scientists at Standford University have implanted human nerve cells into rat brains. The cells grew and became more complex.

I’m not sure what this will do for humans but the rat just matriculated into MIT (apparently the rat doesn’t like California, too much competition…). KIDDING!!

Apparently this could lead to a number of treatments for human conditions.
