We are all going to forget some important things of our lives, even some of us sometimes forget what we did the other day. It is normal to happen, because, over time, without speaking about the memories of the past and giving too little importance to those who are part of daily routine, we begin to forget.

Have you noticed that some things that we remember well and hardly forget, are those that once marked us? These are better stored in the brain area responsible for memory, because of the intensity they had it and so we don't forget too quickly.

For the involuntarily forgotten things, researchers have discovered a possible way to stimulate the brain and make it to remember the past. Some people would think before using this method, because it involves injecting a virus, genetically modified, directly into the brain.

So far studies have been conducted on laboratory rats, but researchers say the virus could be modified and could work on people too.

Memories of the rats are associations between a specific taste, saccharin, and an unpleasant stimulus caused by injecting a drug that produces nausea induced. The research approach is called "conditioned taste aversion". If this combination is not consolidated, meanwhile the memories fade, but not disappear entirely, as scientists said they thoroughly researched over two weeks.

Scientists know that injecting to rats a substance that blocks the action of an enzyme in the brain, called protein kinase M, helps accelerate the process of forgetting. On the same principle, have created a substance that is opposite, accelerating the process of remembrance.

So they created a virus that increases the production of protein kinase M and were injected into the brain area responsible for memory. This virus was administered to rats one week after they have been applied conditioned aversion. Until that time, the animals had already begun to lose their memories.

At the tests performed a week later, the animals had significantly improved memory retention. Scientists do not yet know why this happens, but still doing researches.

So, we are expecting people results, then we can go peacefully to restore our memory. Pleasant memories!
