This is the follow up video to my other video called "How the Internet Redesigns your mind." This is more about the specific brain mechanisms that make the internet (and substances) addicting. I'm not recommending to entirely give up the internet, but it's very important to understand how it's affecting your brain so you don't start to get controlled by it.
If you're interested in this topic, I recommend checking out Nicholas Carr's book "The Shallows" (http://amzn.to/2na38dq)
Jerry Mander's 1978 book "Four Arguments for the Elimination of Television" (http://amzn.to/2nGkZg6) is another very interesting book that discusses the danger of haphazardly introducing pervasive technologies into our lives.
Special thanks to Dr. Kent Berridge of the University of Michigan. He was very generous in clarifying to me some points about dopamine receptor downregulation's role in addiction. He has a very interesting talk on the neural bases of wanting and liking on UCTV ( https://www.youtube.com/watch?v=6f_PdZxaHpU )
