Novelty in the Striatum, ADHD, and Computer Games

We're having connection problems, so just a quick post.

Here's a new article showing a role for the striatum (in the purple box) in novelty or saliency processing.

This is interesting because of the implication of striatal mechanisms in ADD or ADHD-diagnosed children, and because of striatal pathways of learning and reward.

The behavioral checklists do successfully separate different types of childrens on the basis of behaviors, but the question is, can we learn more about better educational environments from the neurobiology?

The second link below is to an abstract (no free online yet) which found that boys clinically-diagnosed with ADHD performed best in the most demanding computer game play situation (high working memory load). On the easier task, they finished quicker, but also didn't perform as well.

Maybe this has implications for novelty learning or challenge?
