Neuroscience of Creativity

This is the first of 7 videos of a talk on neuroscience. It doesn't speak about creativity right away. It says that the more enriched an environment is, the more dendrites and connections the brain has. I remember that sort of lesson in high school. That's why I think that someone's I.Q. isn't completely genetic, and the more enriched their environment is at an early age, the better brain they will have. I do think that people can raise their own intelligence, yet not drastically.
The speaker said that those people with AD/HD are often that way because they are subject to many hours of television and video games. The constant flashing colors and changing scenes cause their brains to want constant change. The main reason is that they are watching a scene and not being directly part of it. Reading a book isn't the same because we get more absorbed in it. I do think having a screen culture has made our brains different than people's before.
I have wondered if something such as AD/HD exists. It's not a real condition, but something as a result of other things. Too much stimulation and anxiety reduce attention spans. People of above average intelligence are always seeking stimulation and get bored easily when something doesn't interest them. I think that it's sad that so many children are put on drugs for AD/HD and they have other conditions or are even gifted.
