Can You See My Brain?

            You often hear, “maybe if I had a bigger brain, I could be smarter”. Conversely, there are those little teasing putdowns you get from your big brother, where he calls your brain tiny or puny. But has anyone ever really thought about picking up one of those old noggins and taking a look? There are actual studies that have been done to correlate brain behavior with different aspects of the brain itself. Research has been done in order to deduce which kind of brain would belong to a particular individual. The idea that stems from all of this is that the structure of the brain (depressions, indentations), affects the knowledge that one has or uses toward a particular goal. To an extent, in my opinion, it is a very probable notion that different features of a person’s brain may dictate the types of activities or abilities that that individual may have or are drawn to. I mean, this would explain why some people are more inclined to play sports, or be an artist, or to even be musicians. Of course there really isn’t a way to “pick up” the brain as I mentioned before (unless you’re dissecting in a lab). The traditional ways of looking into the human body are by the use of devices; such as a CT scanner or an MRI. If you know anything about getting an MRI it’s that you’re enclosed in a “tunnel” of sorts and asked to lie perfectly still. Now for people who are claustrophobic or get fidgety after being in one spot for a while; is the brain activity at that time really accurate enough to conclude anything about it? This is the one flaw (there may be more, who knows) that I find in using these projected images and recorded data.
            In the case of brain damage, researchers determine which ability is affected by the impairment of a certain area of the brain. As a way of attempting to figure out this out, they look to see if brain activity can be increased by stimulation. That’ s all fine and well, but they are not accounting for the fact that activity may be stimulated by not just one area of the brain but in fact several. So while they are stimulating one area, the activity they are seeking to uncover may not be displayed, because there is an additional area that is not stimulated and was needed to be in order to convey a particular activity. However, the practice of brain stimulation is done frequently in the U.S.  The patients are actually awake during the surgery and their brain activity is recorded. I have included a link below to an exciting video involving this procedure!

            Determining what areas of the brain gives us our particular talents, interests, or knowledge is nor a black and white or clean-cut task. It is more complex and takes advanced, experienced individuals to uncover what’s really going on underneath that skullcap of ours.

  1. Definitely advancements in neuroimaging technology has helped humans explain inherent behaviors we may not otherwise know of, if not for the MRI, CAT, fMRI, EEG images etc... Ironically, when we as a human race advance further and further into knowledge about ourselves and our universe, we present ourselves with even more questions and confusion that may boggle most, but fortunately (unfortunately) to scientists it just grants them more power and authority to think that they can temper and play with natural and unexplainable phenomenon that have previously staggered other people. I, however, am for discovery and furthering knowledge, which is one of the reasons why I chose to study Psychology...

  2. The brain is so remarkable in many ways. I believe that some people have the same size of brain but how we determine who has stronger points, is a question to me. I know that the right side of the brain signifies the artistic views of a person etc. and the left is more into mathematics, etc. I know reading about how when Einstein deceased they dissected his brain in many parts around the world. Thus, determining if he had a bigger brain area than a regular size for a human being, there was no difference.

  3. I think the questions you pose, are interesting and you are right when you say it is not "clean-cut" task to figure out what gives us our talents. Despite all of the wonderful discoveries that have surfaced over the years, it is mind-boggling to think that even though our brain function/structures are the same, we specialize in very different areas based on our interests. It is wonderful to see that these advancements in science have allowed us to further understand the functioning of our brains, but unfortunately not enough to see into the its relation to our behaviors.
