Tracked on Brain Speed Talking
Only in 600 milliseconds, the human brain can think of a word, apply the rules gramatik, and sends it to his mouth to pronounce. For the first time, researchers have traced the sequence of these super fast, and break it into different steps. Researchers managed to solve it, by studying the signal sent from the electrode implanted in the brains of epilepsy patients. These electrodes helps the surgeon to find the position of the brain that cause epilepsy, so they can be eliminated. It would also maintain a critical part of the brain, to no surgery. 'If we are wrong to shift a few millimeters to the left or right, we can eliminate the ability to speak or play their piano, and this is very unfortunate,' said Ned Sahin of Harvard University, researchers who study the language network.
With assistance from the electrode monitoring, which monitors the patient's language ability, Sahin and colleagues can perform simple language experiments with volunteers who are interested in, and witness the process of language in real time; essentially, electrodes can be read more clearly nervous processes, dibandingkand ith monitor technology traditional brain, such as MRI.
Broca's area is a major part of the brain was investigated by Sahin and colleagues, is situated on the cerebral cortex. This area is found and is considered vital to the process of language by the French physician Pierre Paul Broca, in 1865. However, according to Sahin, there are still many things that must be examined from that area. Is the process of language took place in parallel or sequential is one of the puzzling questions about the brain.
Elektrodi new studies, described in the journal Science on October 16, has brought scientists one step further to understand the language production in the brain, especially the construction of words and grammar, and then say the word.
By monitoring the brains of three patients when they do the job simple language (see a word, use it in the language or change the tense, then simply articulating), Sahin and colleagues found three activity periods in the Broca area at 200 ms (after the given word) , 320 milliseconds and 450 milliseconds.
Third period was associated with three basic components of language: words, grammar, and phonology (the organization of the word). Thirdly it is also terlingkup at 600 milliseconds needed to talk.
The discovery shows that the third-language production is involved at different times, not in parallel, said Sahin. Further studies will be needed again for that.
