Requirement
As you read the postings of your classmates, consider how you might add to the discussion. You could ask probing questions, offer examples, share a different perspective, seek clarification, add your own insights based on your experiences from outside this course, etc. Avoid brief comments like, "I agree with Helen." Your goal is to add to the discussion so that further understanding develops. I expect from each participant at least two postings in response to other student answers (this is in addition to posting your answer to the DQs).

This website shows that the left side of your body is controlled by the right hemisphere and vice versa. It demonstrated that while the right hemisphere could not calculate complex problems or advanced words it was able to associate those objects with memories and feelings. It thus proved that the right hemisphere is in fact the creative side of the brain. The left hemisphere was more logical and could analyze and could solve problems. However it couldn't make the connection between the answers of the different problems and the context the object was supposed to be taken in. For example Mr. Split Brainy saw and correctly labeled an object as a face but failed to recognize whom that particular face depicted. Thus the site shows that ultimately you need both hemispheres in order to solve problems and then associate and connect them with your life.
I found it very interesting that the website shows how different parts of the brain are spread out along both halves of the brain, yet they are also concentrated on one side. Since the two halves are unable to communicate with each other it is easy to see how one side would take information and process it in a differnt way then the other side. As Walid has stated before, this is most apparent in the way that the the patient looks at the face in two ways. It is easy to see that on one side the linkages to see and understand the face are not as developed on the other side and the same goes for the word problems and the math problems that are presented. This shows that the brain is split up in the dominance of functions but each side still retains parts of the necessary linkages to allow the actions to happen when the brain halves are split.
Although the game was not really fun, it was informative. While we did learn (that the right brain could see images but could not respond and that the left brain could read and solve math problems)from the book, I liked how this went back to the scientists. It's not surprising that the scientists were baffled at one point. At first, the Mr. Split Brainy could not respond to anything shown to the left eye. So they assumed that he might be half brain dead. Upon a second experiment, they learned that he was able to pick the corresponding object to the visual presented to his left eye, right hemisphere. Although he did not know why he picked it up, it showed the brain knew, but he could not process it.
PS how many comments do we leave on this question?
The website did a good job at breaking down the hemispheres of the brain.I agree with Walid about the website doing a good job at showing what the function and need for both hemispheres of the brain is. Also, i thought it was amazing how Phineas survived. Luckily, just his personality was the only thing really messed up which is expected because the frontal lobe was damaged most. Personality, emotions and logic all occur in this region. When someone suffers from a major head injury i think its fair to assume brain damage was responsible because the way you act depends mainly on your mindstate.
I think that the other people that posted above pretty much covered it all. This website went to prove the differences between our two brain hemispheres. The right hemisphere was able to recognize what was flashen in the left vision site, but wasn't able to verbally say what they saw. However, the left hemisphere was able to verbally say what it saw in its right vision site. What I thought was interesting is that even though the right hemisphere knew what it saw and knew which object to grap, the left hemisphere didn't know what it was doing. It was like two different people completely. I thought that this was very interesting and the website made it fun to learn this information.
MRS. ALSTON!
I accidently posted my first two comments for this blog in period 6s blog post
Sam and Walid:
I agree that the website did a good job of explaining the differences in the hemispheres. However, I didn't catch that the website showed how tasks are spread through both hemispheres as well as concentrated in one, but that is a good point.
the website shows that the left hemisphere is connect to the right side of the body and that the right hemisphere of the brain is connected to the left side of the body. The website aslo show that a conncection between the two hemispheres are connceted through a huge bunch of nerve fibers called corpus callosum and that this corpus callosum is served due to a form of epliepsy not curable in any other way in the 1960's. The website shows that the right brain could see images but could not respond and that the left brain could read and solve math problems. From what the information told you, you need both hemispheres in order to slove problems.
the website was very informative to how mr.split brainy associated objects and memories and sloved the problems he was shown. How he used his right side of the brain to create images of what he saw and then his left side of the brain to calculate problems.
That website was rather bizarre. But it explained the roles of the left and right hemisphere's of the brain and how they play a part in day to day life. The left hemisphere seemed to be dominant, although the right hemisphere was able to identify the object by touch without actually knowing what it was. It makes me think how different our lives could be if both halves of our brain didn't communicate with one another. I would be a completely different person and I would see the world in a much different fashion.
the website was interesting to see how split brained people view and interpreted words and pictures. When the same picture was shown to a left or right eye, the brain came to a different conclusion. Being a split brained patient would change anyone and they would become someone completely different.
Alex:
I believe that the website showed that the processes are spread out because it showed that one half of the brain was able to see the basic outline of the face, while the other half was able to see the details of the face and understand more about it. This shows that while one side is not as good as the other at certain tasks, it still retains some ability in that task.
Erick:
I agree that the website was a very interesting explanation for the split brain phenomenon. I believe that it would be very strange to have two different minds working in the same body and with different parts of the body. This could cause many problems for the person as can be seen in the stories found in the book of someone's left hand trying to strangle them while they slept and putting food back that the other hand had gotten down.
Sam
Yes, this would explain those stories of hands that mysteriously try to strangle the owner without the owner trying to kill himself. I really can't imagine my own body working against me - trying to harm me. I would literally feel like someone else was living inside of me.
Delfina:
Yes, I'm glad you mentioned the corpus callosum. This is what keeps our minds altogether. For Mr. Split Brain, his corpus callosum had been severed. This creates two different minds, almost two different beings. Without both hemispheres working together thanks to the corpus callosum, solving problems and putting words to ideas can be quite a problem in itself.
The slide show did a really good job of explaining which part of the brain controls which part of the body. It also gave a visual of how people who have a split brain, like Mr. Split Brainy, have trouble comprehending what they see on the left or right side of the body. What i don't understand is how Mr. Split Brainy was sometimes able to pick up the correct object without even seeing it on the screen. He was able to correctly pick up the shark when it was shown, but when a math equation appeared on the left, he picked up the wrong object. There must be more than just having the visual cortex see the picture. It might be what the right and left hemisphere control. Right controls visual imagery, music, and face recognition. Left controls language, math, and logic.
I agree with what Jen said. Mr. Split Brainy did not have a half dead brain at all. If function just like any other brain, except that he was having problems seeing images from his left eye. Somehow he was able to pick up the correct objects that were shown, thus meaning that we use our brain in way more ways then just visualizing an image and picking up that object we saw.
I agree with Brian on how important it is that both sides of our brain communicate with each other. There must be a good reason why one side of our brain controls the opposite side of our body. It might be to balance our brain and body and the brain could pick up on some of the functions of the other side of the brain if it started failing. Think about this, what if the left side of the brain controlled the left side of the body and the right side controlled the right. Then if one side of our brain failed, then would we become a complete left or right sided person depending on which side failed?
There really isn't anything else to say about this that hasn't been said again and again. This slideshow just covered the basics of the unit we just learned. The website did however do a good job of explaining the differences between the two hemispheres. The split brain experiments are very interesting in that they showed how the different sides of our brain interprit the same thing in different ways.
It was interesting how it showed the different parts of the brain and how they are associated with certain aspects of our personality. They showed how our left side of the brain controlled the right side of our body and vice-versa. The left hemisphere is shown to be the more analytical part of the brain while the right side showed more of a creative thinking mindset.
I agree with Brian and how both sides of the brain need to cooperate with each other. One side enables you to solve problems analytically. The other side helps you associate it with real life situations. WIthout both sides, I believe it would completely change how a person is.
Those stories about your body working as if you had two different personalities is very interesting. It seems impossible but obviously it could happen if your hemispheres couldn't connect with eachother.
The video displayed how the left hemisphere connects to the right side of the body and the right hemisphere connects to the left side of the body. As we now know, the right side of the brain is considered the creative side whereas the left side is the more logical side. Normally there is a connection between the two hemispheres through a huge bunch of nerve fibers called the corpus callosum. The Corpus callosum can be severed due to a form of epilepsy not curable at that time. Basically the video explained that in order to function properly we need both hemispheres.
I agree with everyone who said the split brain experiment was interesting. split brain experiments were actually done with patients experiencing seizures. The separating of the two hemispheres actually led to the discoveries of the two hemispheres being different.
This was a very interesting way to look at the two hemispheres of the brain. It should that the righthalf of the brain saw words with pictures to understand them. when you should the left aeye the would pig the right half saw a pic of a pig and then said it was a pig. Anything to difficult to think of on the lefdt eye he did not get, like the math problems. he saw them but he could not figure it out. this was easy to him when he saw it on the right eye. this shows though that the brain is an amazing thing that even after being cut in two it can still function, not perfectly but to the extent that Mr. split brain's wife can't notice.
I’m not really sure what to say here, I feel like anything said would be redundant. I thought this was a cute way to learn, it kept my attention easier than the book does. The story about your body having two different personalities is creepy…and a little interesting. I think that Mr. Split Brainy made everything seem happy, but when we watched the split brain video in class it showed lots of the trauma that came along with it.
I agree with Sam in that one side can be more dominant in some situations while the other can be more dominant in other situations. I believe that is what makes ceratin people better at certain things is that one side of their brain is more dominant than the other.
Although the game was not really fun, it was informative. While we did learn from the book, I liked how this went back to the scientists. It's not surprising that the scientists were baffled at one point. At first, the split brain patient could not respond to anything shown to the left eye. So they assumed that he might be half brain dead. However, it is interesting how they figured out his actual abilities
To Sam and Walid:
I found it interesting too how the website showed the limits of each hemispehere, both in how some things are isolated in one, or can spread across to two.
To Erik:
I thought it was very interesting how people essentialy had two minds and how they reacted as split brain patients, but do you think this could help anything and not just be interesting facts
Brandon:
I agree with the people you agreed with, however that chain works out. To say the least it would be incredibly difficult to make sense of the world around us when our two hemispheres do not communicate with each other.
Nick:
I thought that having two minds was interesting as well. In the second test, it was as if his arm was possessed and picked up the corresponding item without his other hemisphere knowing it.
The website shows the various facets of a person who has split brain disorder, in which their corpus callosum has been severed.
This severance does not allow messages to relay from one side of the brain to the other. This creates problems where if a person with split brain disorder see something their left eye, they are unable to put a name to it, where are if they see something in their right eye they can put a name to it, but they can not visual the image in their mind. This provides clues as to how the brain processes sensory information in the different hemispheres of the brain.
In response to Nick I believe that understanding the fact that a person with a split brain essentially has two brains is more than just an interesting fact. This information can lead to scientific discoveries that will help the world understand exactly how we think
I do feel strange about the website, the animation was done in the vein of Salad Fingers which is mildly disturbing to think of, perhaps the site would be more informative if it provided videos of actual split brain patients
Sam: i agree it is intresting to note how each hemishpere of the brains thinks in a seperate way either more analytically or creatively
