The English and Hebrew languages are opaque, which is not read as you type. The Castilian is just the opposite, because each letter has a unique sound. And the Chinese have a logográfico alphabet, in which each sign represents a word.
They are very different languages that are written, read and spoken in many different ways. However, in the brains of its speakers common areas are activated both to decipher the language written and oral.
The data of an investigation, conducted jointly by the Basque Center on Cognition, Brain and Language (BCBL), Yale University (USA), the Hebrew University of Jerusalem (Israel) and the National Yang-Ming University in Taipei (Taiwan), suggest “it is a universal principle of brain organization “in the words of Kepa Paz-Alonso, a researcher of the Basque center and author of the study.
The overlap between the neural networks reading and comprehension seen in the brains of speakers of four languages analyzed
It has been shown that both reading and listening Common words brain areas are activated. Although when we read a text or hear a voice perceive such stimuli through different senses (sight and hearing, respectively), there are areas of our brain that are activated when we perform either of these tasks.
That overlap between the neural network of reading and understanding of the language has been observed in the brains of speakers of four languages analyzed, so the researchers believe is a universal principle.
In this work, published in the journal Proceedings of the National Academy of Sciences (PNAS) , researchers have studied the brains of 84 volunteers, 21 per language. While they had read or hear different words, their brain activity was analyzed using a technique known as functional magnetic resonance imaging, through which you can watch the brain regions involved in a particular task.
“We chose a as different languages because this way we could see better if the way you read and understand spoken language in different languages have more or less similarities in terms of brain networks responsible for processing that information, “explains Paz-Alonso .
“It would be inefficient to have two completely separate systems of language or with little convergence among themselves to understanding and reading”
“Since the Spanish reads like it is written in English or in Hebrew is not, you might think that a speaker of the latter languages should activate different brain networks, and yet it is not so : the same regions are activated in all languages, also in Chinese, which follows a completely different system, “adds
Convergence between neural networks
So, a convergence between the two networks occurs because the brain network dedicated to the understanding of spoken language serves as a scaffold for reading. Since this phenomenon has been observed in the speakers of languages as diverse as the above, researchers believe they have discovered “a universal principle of brain organization of language” in the words of Paz-Alonso.
” This implies a certain economy in brain organization surely be inefficient systems have two totally separate language or with little convergence among themselves to understanding and reading, especially when one of them has previously developed, “says
Following these findings, researchers are raising new issues. For example, although in different languages common brain areas are activated, they communicate in a similar or different, or to what extent it affects the ability to read how the brain network dedicated to understanding is established, which is set before the development of language.
