@astrobambina Ok.... Prima di tutto parli italiano?
If not I'd say, in first place, that your question is not actually answerable. I mean what do you mean by internet, all the virtual things? All social networks? Everything associated with technology? What exactly. Second what do you mean by addiction to our brain? You meant something like: " how is modern technology changing our mind? Does our mind get addicted to that technology? "-. And what do you mean by brain? How we reason or behave?
If you remake the question, in order to solve the doubts I've just showed you, I'll try my best to answer.
What I can say is that, for sure, our brain is stimulated, I mean the way technology stimulates both our way of thinking and behaving is something true. Our brain is "fascinated" by something that can reduce time and space so much, it's involved even on a intellectual level, I mean computer skills are something that require a lot of mathematical, logical and analytical thought. Our brain is like challanged by technology, not only to improve but also to "hack it", I mean sometimes it's a "who mock the other first", for example sometimes it's preferred not to solve the problem, but to bypass it. But whatever... probably that is not your question.
