Wow! That just blows my mind. I don't understand how the guy with the split brain doesn't know what the object is until he draws it. If he is able to draw it with his hand, wouldn't he already know that he saw the object and picture it in his mind? Plus, why does one side of his brain go "mute"? What factors decide which side of the brain stays in communication and which one goes def?

That's incredible! But why can't he name the picture on his left, but he can draw it??

So I get that the two sides of the brain work seperately, but I don't understand why. What function specifically does the left side of the brain have that makes him able to see what's on the right side of the dot? And what function doesn't the right side of the brain have that makes him only able to draw the object after seeing it?

Sarah,
Each hemisphere of the brain has its own separate functions. In a normal brain, they work together and you don't notice any abnormalities. In split brain patients, the lack of a corpus callosum prevents the two hemispheres from communicating with one another.
This make it appear that the brain is acting somewhat independently of the user's body. The guy in the video still sees the objects, however, he can't draw it. We'll discuss this in more detail on Monday of next week.

What would happen if this were performed to a left-handed person like me?

I think it's crazy that the brain works that way. It's amazing how he can see the object but not realize that he saw it and doesn't know why he drew a picture of it.

So fascinating to see how both hemispheres can work independently of each other in their separate tasks, as seen in Joe, compared to a normal brain functioning all together. It was also very interesting to see the power of the unconscious, when Joe could not say what he saw, but he could draw the object.
