The brain is always trying to compensate for the other parts of my brain. As it ramps up its activity, it suppresses everything else. The first thing that you've got to do is reset this ecumbents. If i spend 60 hours a week playing a video game, do i have more fun or less fun than if i play a game for six hours a week? So what's the most common cause of under activity of the nucleus ecumbents? Is dopem inergic over stimulation.
