In my last post I mentioned that Jonah Leherer’s new book, Imagine, had brought up the teamwork between our left and right brain hemispheres.
In biology, we learn most when something is missing. If all parts of a brain are participating, it’s hard to tell what each part does. But if some parts aren’t working, we notice the problems. We can assume the damaged or missing parts are connected to the problems. So brain researchers frequently recruit volunteers with brain damage.
When people have lost some right brain function, some strange things happen. Asked to draw a house, such a person may draw scattered details: a disoriented roof, individual bricks, a window sill. But these details are scattered and don’t make a real “picture.”
On the other hand, people with left brain damage may draw the shape of a whole house, minus its details.
People with right brain damage often don’t get jokes, or don’t comprehend metaphors. People with left brain damage may lose names, or words, or the ability to speak.
Clearly, we need both hemispheres to function fully in a number of ways. The cooperation of both halves has a lot to do with what adds zest to life!
