After reading the Biological Psychology chapter in the textbook, I was intrigued when the authors began to discuss the myth that humans only use 10 percent of their brain. This immediately had me thinking of a movie that recently came out called "Limitless" starring Bradley Cooper.
The following link brings you to the trailer in case you have not heard about it or seen it: http://www.youtube.com/watch?v=THE_hhk1Gzc.
This movie plays of off this myth that more of our brain can be accessed and used to further our brain activity. In the movie it is stated that humans only use 10 percent of our brains; however just by reading our textbook, we know this is not true.
The pill (NZT) that the main character in the movie takes allows him to access the "other 90 percent of his brain), and while this makes for a good plot, we know this is not true. Humans use every part of their brain and as stated in the text, damage to even the smallest part of the brain can take a toll on its overall function.
So we know that humans use every section of our brain but not simultaneously. The real question that I pose, and which I think would make for a more realistic plot, is what if a pill or drug was created that allowed us to access and use every part of our brain simultaneously?
If this was biologically possible, what would be the result?
What if we were able to turn our subconscious in to conscious thought and action? What if we could consciously control the bodily functions that are currently controlled by our subconscious?
Despite the fact that this is far from achievable, with regard to where scientists currently stand in understanding the brain and the possibilities that come with it, it is still a intriguing idea to toss around in our mind.
Ps: I highly recommend watching this movie. It's pretty mind-blowing despite the fact that it is based on an urban legend.
