How does the human brain function?
The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. But the brain can do much more than a machine can: humans think and experience emotions with their brain, and it is the root of human intelligence.

What does the brain need to control the body?
The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you’re less aware of — like the beating of your heart and the digestion of your food. Think of the brain as a central computer that controls all the body’s functions.
Can the brain heal?
Your brain does eventually heal itself. This neuroplasticity or “brain plasticity” is the more recent discovery that gray matter can actually shrink or thicken; neural connections can be forged and refined or weakened and severed. Changes in the physical brain manifest as changes in our abilities.
What part of the brain is responsible for happiness?
Imaging studies suggest that the happiness response originates partly in the limbic cortex. Another area called the precuneus also plays a role. The precuneus is involved in retrieving memories, maintaining your sense of self, and focusing your attention as you move about your environment.
