In the brain detected centers responsible for getting rid of memories
Source:
A Large number of studies aimed at studying the processes of memory and remembering. And, in General, they have been studied quite well. But how is the process of "physiological" forgetting (that is, not associated with a neurodegenerative process), was known to very few. And not so long ago a group of scientists discovered in the brain Department, which is responsible for «wipe».
Responsible For the discovery of a group of neuroscientists from Germany, Switzerland, Holland and the UK and their work, says the publication Current Biology. During the research, scientists found out what happens in the brain when a person tries to forget something. It turned out that the responsible prefrontal cortex and hippocampus. But not all so simple.
For the experiment, were involved 22 patients who were implanted special electrodes that register brain activity. The researchers then called the words that you want to remember and those to forget. Of course, to forget the words is not so easy, especially especially. However, the results of the experiment revealed that participants in the worse remembered those words that "need to forget".
After the final poll signals from implanted electrodes were collected and analyzed. It turned out that the hippocampus (temporal lobe) and prefrontal cortex (frontal lobe) at the time of the command to "forget" any rhythmic activity. Moreover, had it first in prerenalnaya the bark, and then "moved" in the hippocampus. The last structure has long been known as one of the centers of memory, but the fact that he is responsible for the forgetting of information, confirmed for the first time. The authors argue that the new data can help in the development of new methods for the treatment of post-traumatic disorders and to help people to get rid of unwanted memories.
