Every animal you can think of -- mammals, birds,
reptiles, fish, amphibians -- has a brain. But the
human brain is unique. Although it's not the largest,
it gives us the power to speak, imagine and
problem solve. It is truly an amazing organ. The brain performs an incredible number of tasks including the following:
- 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 and touching).
- It handles your physical movement when walking, talking, standing or
- 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, spinal cord and peripheral nerves make
up a complex, integrated information-processing
and control system known as your central nervous
system. In tandem, they regulate all the conscious
and unconscious facets of your life. The scientific
study of the brain and nervous system is called neuroscience or neurobiology.
The human brain is so intriguing. Take a little time to read the following:
