American scientists announced that they added a NR2B gene, an important switch that controls the brain's ability to associate, to the brains of mice. It works with a brain receptor called NMDA, which is like signal station.Joe Qian, a neurobiologist at Princeton University, said that when the genetically modified mice grow older, their brains still maintain some characteristics of the brains of young mice, and their learning ability is greatly improved, just like a car with excellent performance. These advances prove that it is possible to increase the intelligence of mammals, including humans.
