The brain has six layers and is protected from everyday bumps by fluid, bone and hair. It weighs three pounds and when you’re awake it generates enough electricity to light a light bulb.
You are born with billions of nerve cells and your brain has more connections than there are stars in the universe. It deals with hundreds of messages every day from the world around you and also from your body, and it tells each part of your body what to do.
The cerebrum is the largest part of the brain is divided into halves, the left and the right hemispheres. Each hemisphere largely controls the opposite side of the body, the left hemisphere controls things including speech and language while the right hemisphere controls creativity and musical skills. Each hemisphere has four lobes these are the the frontal, parietal, temporal, and occipital lobes and they all have various and very important responsibilities and functions. The hippocampus- which plays a very important role in memory is located in the temporal lobe.
