Do the new technologies are rewriting our brains?
How the brain looks for someone looking for material in Google? All those hours you spend online; can rewrite the circuitry of our brains? These are questions that have been made psychiatrists and neurologists.
There are no firm answers, but Gary Small, a psychiatrist at the University of California, argues that the daily exposure to digital technologies like the Internet or smart phones can affect brain function.
When the brain spends more time on tasks related to technology and less social with other people, away from fundamental social skills such as reading facial expressions during a conversation, said Small.
So the brain circuits involved in face to face contact may become weaker. This can lead to social discomfort and an inability to interpret non-verbal language, including insulation.
According to Small, the effect is stronger in the "digital natives", or adolescents and those in their years who were born and reared in the digital age. According to Small, it is important that young people improve their social skills and improve higher technology skills.
The point is that since writing and reading we changed for thousands of years, not just our culture, how we see the world, how we express ourselves, but our brain circuits. Also in those days there were detractors, like Socrates, who warned that the written word would change the thinking.
The issue is that people are adapting to these new technologies and society as well. Take the good, the bad and leave. I will say that there are those who do not leave much, or seen in person with friends often, but you can say that now speak several times a day with different friends, and through new technologies could make new friends previously could not.
Neuroscientists believe that perhaps the new way of reading online can rewrite our brains, as it tends more to reading than to read a thorough and comprehensive, they say.
It is a matter of wait and see, any new technology is met with suspicion.
Where do they come from the words?
More than once in a conversation and a half of a sentence cannot find the right word. If you miss one then immediately branded as being older. But researchers at Rice University, the United States, discovered that a particular region of the brain that is involved in choosing words.
With a computed tomography image of the brain regions which are known to produce speech, light up when a person is trying to decide between two words. These regions in Broca's area and left temporal lobe.
The words are very important to humans because they are precisely those that make us "human." Humanism is a broad term, can refer to the genus Homo, as well as the behavior that we call human, that is precisely what distinguishes other primates us.
It is unclear when they began to talk, but it is believed occurred between the ancestors of Homo sapiens, perhaps the last common ancestor we had with the Neanderthals.
But a perfectly designed language as we have today is believed to make just started appearing about 100 thousand years. Depending on the language, a person has to choose between many words for a given situation. It is important to know where it takes place this decision in the brain, to help those who have problems.
