The video gives you an idea of the graphics, as well as the target audience (citations are annoyingly targeted at parents).
Neuromatrix is an NIH-funded video game developed to teach children about their brains.
In the game, you play a secret agent infiltrating a top-secret neuroscience research facility. Your mission: to track down and root out the Nanobots that have invaded the brains of the scientists there. If you fail, the Nanobots and the secret entity that spawned them will take over the Earth, reprogramming the human brain into docile submission.
The game was developed by Morphonix and is recommended for kids age 10-15.
