Hello, I'm back! Hope you're all doing well! Today I'm going to be posting about the movie "Lucy."
So, according to wikipedia and the movie trailer (I've never seen the movie myself), this movie's about a woman named Lucy (Scarlett Johansson)who has CPH4 sewn in her abdomen. She gets captured and in her "prison" of sorts she's eveventually one of her kidnappers kicks her into the stomach, releasing the chemicals into her system, and now she can use 100% of her brain compared to only 10% according to Professor Samuel Norman (Morgan Freeman).. She gets magical powers such as mental time travel, telekinesis, ability to choose to feel pain or not, and so on.
As much as this is a cool fact to believe that we're only using 10% of our brain and if we can use near 100% we'll have powers, it's not true. We use all of our brain.
Many people have used such a myth for their own gain. People sold books and used advertisements saying that they can help "unlock all of your brain." It's reasons like these that In Scott Witt's 1983 book, How to Be Twice as Smart, wrote that most people use about 10% of their brain. Now of course, I haven't read this book, but I do know that most people, if not all of them, use 100% of their brain.
It doesn't make sense if we only use 10% of our brains. They have been shaped by natural selection. Our brains weigh 2-3 pounds but takes about "...20% of the oxygen we breathe" (22). Evolution wouldn't allow only 10% of our brains to be used because they help with our survival and reproduction; why would the brain want to hold back information that can possibly help us; "It's hard to believe that anhy slight increase in processing power wouldn't be snapped up immediately by existing systems in the brain to enhance the bearer's chances in the continuous struggle to prosper and procreate" (22).
In addition, there have been patients that have lost 90% of their brain due to accidents or diseases. The results are always saddening. A woman named Terri Schiavo layed in a 15 year vegetative state after her cardiac arrest destroyed about 50% of her cerebellum (23). Patients whom have been in similiar scenarios like Terri Schiavo have permanently lost many abilities; "...the capacity for thoughts, perceptions, memories, and emotions..." (23). Why is it, then, that if patients like Schiavo lost 50% of her brain, lost her ability to do things that make being alive so great?
Strokes and head traumas also leave patients with serious deficits. When areas become "quiet", then that function is affected and the patient is generally unable to complete the task that the brain area is responsible for.
Areas of the brain that aren't used generally do one of two things: 1) they degenerate or 2) they're taken over by other areas of the brain (23).
So their you have it. These are some of the reasons why we use more than just 10% of our brains. More reasons can be found by looking it up on Google or reading a book about it. You can also find out more myths from the article that I'll cite/ talk about under the disclaimer.
Now I'm not trying to be a fun sucker or ruin the movie for you. If you want to pretend that we don't use all our brain while watching the movie, then that's fine. It is just a movie after all and it's always nice to get away from reality just for a bit. But if you see someone try to talk you into believing the 10% brain myth or sell you a book based on this "fact", then turn the other way or argue back with the person (hopefully using the article this blog post is based on).
Anyways, I hope you enjoyed reading and I'll make sure to post again next week!
