What is memory?This question not only has been plagued by scientists in the field of cranial nerve, is also our curiosity by the general public.Now, we finally a step closer to solve the mystery.
Scientific research team from the United States at the university of Oregon released a new achievement, scanners and EEG relies on the latest electroencephalograph (EEG) scanning method, they succeeded in the formation process of observed short-term memory, and it recorded in graphical mode.
The brain activity in the process of memory formation (image)
The EEG is a kind of method used to measure the current voltage change brain neurons, now the most commonly used to diagnose epilepsy, but few people can think of, it in observing the brain activity and short time has such great effect on imaging.
We now know, short-term activities in brain waves, the formation of memory is actually a process, this process is usually only 20-40 minutes, so has been hard to imaging.
At the university of Oregon, the solution is to focus on study of alpha, the brain waves with occipital lobe brain (core) of the brain's visual processing is closely related activities.In their experiment, participants in a circle, to observe and remember a small bar of Angle, by monitoring the frequency of the alpha, the researchers successfully parsed out each experimenter can see small Angle.
(subject to see what is parsed out)
, said the research team, in fact, it will be many brain imaging methods, our common nuclear magnetic resonance (NMR) is one of them, but, it doesn't have real time, compared with those of the EEG this fleeting brain activity, especially to the memory of the observed information, for the moment, may be in imaging when it has completely changed.
He admits that, of course, this step now, away from the real commercial and distant point, but if continue along the EEG technology research, they can confident there will be a detailed record short-term memory formation time and process equipment, and its reduction.
But for some people, can see your memory devices, or do you really need to have the courage to use it?
(can see your memory devices, it is you need?)
Actually not only the medicine, observe the activities of the human brain in this way, in any form of human-computer interaction has very important significance.The team a lot next scenario, the evolvement of the technology were about the brain control computer, such as raising the mind control accuracy and practicability of the prosthesis.
, head of the research team said, is now the biggest problem, is to find a particular state of the human brain and want a reliable corresponding relation between 'instruction.Difference between the subjects of state of the human brain, the more obvious, the invention is used to interact with prosthetic limbs or computer interface, the feasibility of the higher.
If the corresponding relationship can form stable database, the so-called brain interaction interface has been born, then can realize the function of not only see the memory.
