A third of the world population shares pieces of life on Facebook, Twitter, Instagram and its aftermath have the time spent online and social interactions on our brains and behavior?
The ease with which we surf on the Internet has changed the way in which we inform you.
We spend an average of 8 hours as specialist users to work or 2 hours a day surfing, post and comment on Facebook, Twitter, YouTube and other social platforms. The consequences of this change on the daily lexicon is constantly before our eyes ( “I have tagged in a photo”, “I like to put his status” …). But what are the effects of social media on our brains?

1. Dependence. 5-10% of online users is unable to control the time spent on social. The brain scans of these people reveal damage in the same areas affected in the brain of those who do abuse drugs: there is a breakdown of the white matter in regions that control emotions, attention and decision making. The reason is to be found immediately , the contentment, with little effort, offered by social media, which causes the brain develop dependence on incentives offered by them
2. Multitasking. You might think that the use of social make us better able to handle multiple tasks simultaneously. Proof? We know at the same time keeping an open Facebook window, on Twitter and on email that we are writing. In fact it has been shown that people who spend a lot of time on social becomes less able to switch from one task to another, more easily distracted and less efficient in storing the information in memory.
3. Phantom vibration syndrome. “Wait, I vibrated the phone! Oh no, I’ve dreamed” is a phrase that you happen to speak, or hear more and more often? In fact, one study showed that 89% of respondents feel this test once every 15 days.
The phenomenon on the rise, it seems due to the fact that the smartphone and tablet, thanks to the use of social, follow us now everywhere and appendices in the hands and pockets have become. They are thus interpreted as “phantom limbs” from the areas of the brain that analyze the tactile sensations (such as the somatosensory cortex) and end up interfering with our tactile perceptions
4. Dopamine release. functional magnetic resonance imaging studies have shown that the reward centers in the brain are more active when, in a conversation, we’re talking about us, rather than when we are asked to listen. But if in the face-to-face chats talk about ourselves in 30-40% of the time, Facebook’s self-centered 80% of the post. When we write of us in our brain releases dopamine, a neurotransmitter associated with feelings of well being: it is as if the brain in some way his rewards our self-centeredness!
5. Interpersonal Relations. Maybe for our tendency to spend a lot of time online, studies show that online relationships are born not as ephemeral as believed.
relationships born on the Internet are even stronger than those born offline. The reason lies, perhaps, in the fact that in these stories, before meeting in person will have the opportunity to meet other’s tastes and passions.

Social media are effective if well used, but if used improperly are deleterious and false.
