How Your Brain Works by Craig Freudenrich, Ph.D.

Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- has a brain. But the human brain is unique. It gives us the power to think, plan, speak, imagine... It is truly an amazing organ.

The brain performs an incredible number of tasks:

·        It controls body temperature, blood pressure, heart rate and breathing.

·        It accepts a flood of information about the world around you from your various senses (seeing, hearing, smelling, tasting, touching, etc).

·        It handles physical motion when walking, talking, standing or sitting.

·        It lets you think, dream, reason and experience emotions.

All of these tasks are coordinated, controlled and regulated by an organ that is about the size of a small head of cauliflower: your brain.

Your brain, spinal cord and peripheral nerves make up a complex, integrated information-processing and control system. The scientific study of the brain and nervous system is called neuroscience or neurobiology. Because the field of neuroscience is so vast, and the brain and nervous system so complex, this article will start at the beginning and give you an overview of this amazing organ.
