Massachusetts Institute of Technology to experiment with combining human genes - FOXP2 - and reorder the arrangement of genes on mice, rats produces learning how to find food faster than normal mice.
This kind of experiment has also been carried out in 2009 found, from the human FOXP2 develop more complex neurons, as well as forming a more efficient brain circuitry.
"No one knows how the brain makes the transition from conscious thought to doing it unconsciously," says Ann Graybiel, author of the report at the Massachusetts Institute of Technology, as reported by ABC Science.
From these findings, the team conducted experiments Graybiel and re-used hundreds of rats that are divided into two groups. The first group of genetically modified, and the second group of normal mice.
All mice were housed in a complex maze. The ultimate goal to find food, which is a piece of chocolate. In some parts of the bend in the maze, placed several signs such as "T" for the intersection, "turn to the direction of the chair". So each rat had a choice, pay attention to signs or feel the texture of the floor of the maze - smooth or rough.
As a result, mice that had received human gene engineering can find chocolate in 7 days. While normal mice spend up to 11 days.
Surprisingly, when the signs of the labyrinth was removed so that the mouse can only guess from the texture of the floor, engineered mice and normal mice to find chocolate at the same time.
Based on these experiments, Graybiel develop a hypothesis, that the human gene does not improve cognitive abilities flexible. But the human gene makes rat brain thinks sequentially, called declarative learning. Examples such as we, humans learn to consciously remember the traffic signs automatically when repeating the same road.
The research contained in the journal "Proceedings of the National Academy of Sciences" aims to study the ability of infants to learn language automatically, by consciously imitating the words they hear.
