Babies understand what im talking about

Babies can not understand many words that adults say, because their brain is capable of processing them, say scientists.

Incorporating the latest technology of magnetic resonance imaging (MRI) and magnetoencephalography (MEG), University scientists "Kalofornija in San Diego have proven that children slightly older than one year are processed words using the same brain structures as well as adults.

Researchers found that children not only to handle the sounds of words in mind, but I can understand their meaning.

The study, conducted by Dr. Eric Halgren - a professor of radiology, Jeff Elman - a professor of cognitive science, and Katherine E. Trevis with the Department of Neurology and multimodal diagnostics, said that infants use the same brain mechanisms as adults in uncovering the meanings of words, using what was until now considered a mental "database", ie a database that is constantly updated to "adulthood".

Many are now believed to be newborns, using a completely different mechanism for learning words, learning that ranges from the simplest components and turns in the process used by adults.

Identification of areas of the brain responsible for language learning has not been possible due to lack of evidence that would indicate the area of the brain developed, in which process takes place.

Although the lesions in the two parts of the brain known as Wernicke Bročino and (frontotemporally) area, a long time associated with the loss of language skills in adults, the same lesions in early childhood does not affect too much on language development.

To explain these differences, some say that the right hemisphere and inferior frontal regions in the crucial first language, and prejudiced language areas in the older age become dominant only with the spread of linguistic experience.

In contrast, other theories suggest the hypothesis that brain plasticity in other regions of the newborn to download the tasks associated with learning the language, if there is damage to the left frontotemporal region in the earliest age.

To determine whether the infants used the same functional networks as adults in interpreting the meaning of words, researchers have used the MEG-om, diagnostic that measures tiny magnetic fields that send the neurons in the brain, and MRI-operation in noninvasive assessment of brain activity, 12-18 months old infants.

During the first experiment, children listened to the sounds of words followed similar acoustic properties, but not meaning - to be determined whether they can distinguish. During the second phase, scientists have investigated whether infants understand the meaning of those words.

Within this experiment, infants were the images of familiar objects, and then they heard the words that match or not match the name. Thus the image of the ball followed adequate spoken term, and then heard the word dog.

Brain activity showed that the children failed to establish a mismatch of words and pictures, as was evident by the amplitude of brain activity. "Uncoordinated" or mismatched words evoke the characteristic brain response is placed in the left frontotemporally area responsible for processing the meanings of words in the adult brain.

The tests were repeated in adults in order to verify that the same combination of mismatched pictures / words indicated newborns caused by a stronger responsiveness in left field frontotemporally.
