US Military Research proves that the damaged brain tissue can be compensated by emailektrodami and special electronic implant is implanted in the brain, will help to better remember and reproduce the information in your head.

Who is a special device designed to artificially improve the memory , stimulating the brain with electronic impulses passYat Phase I clinical trials in humans. A study funded by the US military, which hopes that this method will help thousands of soldiers, who have problems with memory th due to various head injuries. The finding that such an implant successfully helps people, presented at a meeting of neurologicsociety in Chicago in late October, two research teams who conduct research commissioned by the Defense Advanced Research Agency (DARPA).

Imitating electrical signals, which reproduce and preserve memories, the researchers found that gaps in memory, damage can befill. They are already talking about « neuroprosthesis & raquo ;, which automatically strengthens weakened memory . The device is able to help both people who received mechanical trauma to the head, and those who have suffered a stroke or a purely age-related problems with the Memorybe th.

Because of the risks associated with surgical implantation of implants in the brain, studies conducted on human volunteers, patients with epilepsy. These people already have implanted electrodes in which both monitor the activity of their brains and use them to stimulate specific groups of neurons.

How does this device? It is proved that short-term memory is formed when part of the brain called the hippocampus, accumulates the sensory information and keeps it within a short period of time. If it is time to indulge in memories, information from SHORT-TERMtion storage becomes long.

The key to this process is a signal that goes from one part of the hippocampus called the CA3, to another, which bears the name of CA1. In one study, who presented at a meeting in Chicago, researchers asked 12 people with epilepsy to look at pictures,and 90 seconds to remember that they saw. Through brain implants at the time fixed, the type of signal sent from CA3 to CA1.

Later, researchers developed an algorithm that is based on the output signal CA3 decodes the input signal CA1. On the basis of this algorithm, scientists have created a method of stimulationchastka CA1 synthetic signal that simulates a signal CA3. In a study in monkeys who were trained to perform the exercises for memorizing images, offering the right answer in the case of juice, we found that stimulation of CA1 corresponding signal significantly improves animals.

In the near futureix months, the researchers plan to improve the device and to test it on a larger number of volunteers. Their ultimate goal - to create an implant that will capture when the hippocampus is not enough signal from CA3 to CA1 and artificially amplify the signal. This Statement « prosthesis » memory.
