Scientists—the human memory can be remove

Scientists from the University of California claim that stimulating nerves with laser, you can remove a certain piece of memory.

According to experts, the technology used by will Smith and Tommy Lee Jones in the popular film, can become a reality. Opening, tested on rats, may have huge potential for treating a variety of phobias. With the help of light it is possible not only to delete unnecessary pieces of information in my head, but to remember something important patients with dementia.

The researchers in their experiments stimulated the nerves in the brain with an optical laser. They showed how the strengthening or weakening of connections – synapses, it is possible to remove or recover the memory. Professor Roberto raspberry says: "We can form a memory, erase that memory and we can enable it, if desired, by applying a stimulus that selectively strengthens or weakens synaptic connections".

The researchers used optical lasers at the specific frequencies to stimulate nerves in the brain in rats, simultaneously connecting the shock to the animal. Rats quickly learned to associate the optical stimulation with pain. The researchers then used a number of low frequency lasers to stimulate the same nerves, erasing memories. In further experiments, the researchers found that can restore lost memories high-frequency pulse to the nerve. Dr. Sadegh nabawi said: "We can cause an animal to fear, and then force not to be afraid and then to have fear again by stimulating the nerves at frequencies that strengthen or weaken synapses".
