Split Brain.jpg

The Split-brain procedure is very interesting. When we watched the video in class of the man who had his corpus callous split in order to lessen his severe epilepsy it was amazing. When an image flashed on the screen to his right side he was able to tell the researcher what picture was flashed on the right side of the screen. This is because the information from the right eye is conveyed to the left hemisphere of the brain. The left hemisphere is responsible for speaking and language.
But when images where flashed on the left side of the screen to his left eye the man was not able to name the picture that was flashed. But he was able to draw a picture of the picture shown him. This is because the information from the left eye is conveyed to the right hemisphere and the right hemisphere is responsible for visual activities and plays a role in putting words and pictures together but this side cannot communicate like the left side.
I find this very interesting because every day we walk around and place names and picture of faces in our heads and we can look at something and place a name with it or hear a name and place a face with it. It does not take us more than a few seconds to remember the objects presented us. But the split-brain patients take longer, especially when it is a picture presented to their left side. They can't say the name of the picture shown them. It is very sad to think that we take for granted the way our brains find information for us.


I found a very interesting game that shows the effects of the split-brain procedure.http://www.nobelprize.org/educational/medicine/split-brain/about.html
