Darkhorse, if you want to build the muscles in your brain. Supercharge the neurons so to speak, then also have a look at a book called "Smart Drugs and Nutrients." Exercise for the brain is one thing, but diet is another.
There are chemicals around that can actually improve communication between the left and right sides of the brain. If fact some research indicates that uncreative people are mearly so, because the neural pathways between the creative and analytical areas are underdeveloped, much like Permabulls brain.
To use an analogy, its like you have two different, yet powerful computers on each side of the brain. Ones a Mac and ones a PC. Everyone has them, but in some people, the ethernet cable is missing.
Athletes have been known to take these smart drugs because they have the ability to improve things like hand eye co-ordination. They can also help you perform simple tasks like drawing a perfect circle. I have yet to test them, but they may also improve your ability to watch more screens or work more hot keys in a given period of time.
There are also chemicals that improve blood flow and others that aid recall. Some elemental minerals can assist in strengthening the neural pathways as well.
There is evidence that these drugs may also slow the onset of age related memory loss. All in all, a very interesting area of research.
