One of the goals of this blog is to share some of the things we can do to keep our brain healthy as we age. Why do we need to do that? How does the brain work?
I turned to How Stuff Works online:
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, tasking and touching).
- It handles your physical movement 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, 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.
As you can see, the brain plays a critical role in almost everything we do. Therefore, I’m sure you’ll agree it’s important to keep it healthy.
