In stories such as Flowers for Algernon by Daniel Keyes, the main character, Charlie Gordon, receives an operation on his brain that triples his intelligence.
Could something like this be achieved if the brain is somehow sped up and forced to do more in less time? And wouldn't something like this cause the brain to deteriorate rapidly from being "worn out" by so much use?
I found in this article that as the brain ages, it will shrink and will have larger fissures in it. In the story, after what seems to have been a short life, the mouse dies and is dissected. The mouse's brain is found to have much larger fissures and have shrinked.
Is this wearing out or aging of the brain due to increased activity by surgical means accurate in any way?
