A new study of sign language does not consider that there is only one advanced area of the human brain that gives to the language skills beyond those possessed by any other animal species. However, to make sense of a sentence using multiple human brain regions, each designed to perform various tasks primitive. Depending on the type of grammar used in the formation of a given sentence, the brain activates a certain set of regions for processing. Something similar when a carpenter chooses his toolbox all these that will serve to bring out the basic components that make up a complex task.
“We are using and adapting the machinery that we already have in our brain,” said study co-author Aaron Newman. “We’re obviously doing something different in comparison with other animals, because we are able to learn the language unlike any other species. But it is because some regions have evolved especially in our brain for language only, and nothing more.”
To determine the different brain regions were used different sentences with different types of grammar, and scientists focused on American Sign Language by a rare quality he has. Some languages (English, for example) are based on the order of words in a sentence to express the relationships between the elements of prayer. When an English speaker hears the phrase “Bob greets Sally,” it is clear from the order of the words that Sally is the one who is doing greeting and Bob is the person who receives it and not vice versa.
In other languages (Spanish, for example) are based on inflections, suffixes and prefixes of words to convey the subject-object relations, and order of words can be interchangeable. American Sign Language has the useful feature that the subject-object relationships can be expressed in either of two ways – by order of the words or inflections. For the study, the team formed 24 phrases and expressed each of these sentences using both methods.
Using MRI (magnetic resonance imaging) monitored the brain areas that are activated in the treatment of different types of sentences. The study found different regions of the brain used to process the two types of statements: those in which determined the order of words and the relationships between the elements of prayer, and those who gave the information inflection .
In fact, in trying to understand the different types of grammar, humans use the brain regions that are designed to perform primitive tasks that relate to the nature of the phrases that are trying to interpret. For example, order a sentence of words are activated in the frontal cortex areas that give humans the ability to put the information in sequences, while turning a sentence is located in parts of the temporal lobe that specialize in dividing the information into its constituent parts.
“These results show that people really must think about the language and the brain in a different way, in terms of how the brain uses some existing structures may computer to interpret the language,” the authors said. In addition to providing insights into how language may have evolved in humans, the findings of scientists perhaps could eventually find applications in medicine. For example, it might be valuable in assessing how best to teach language to a person with brain damage in certain areas but not others, as a victim of a stroke.
