sophisticated human organ, the brain is the body's control
central - responsible for a complex system of neurochemical
and electrical levers that turn on our ability to see, speak,
hear, touch and feel, smile, frown, walk and run.
is the source of our memories and creativity. It effects our
sleep habits, our dreams, and our daydreams.
Even moral behavior can be traced back to the brain, wherein electrical impulses and chemical reactions can have a major effect on an individual's outlook and mood.
Thinking about the brain
Yet for all the advances that researchers have made in discovering the brain's inner workings, even today no one can yet tease out the answer to the most nagging question the human brain
That is, human consciousness or - how do we think about what we think about?
How the brain and nervous system work
More wonders await in the nervous system. which is divided into two parts or "circuits". There is the central nervous system, which is comprised of the brain and spinal cord. The other
major section, the peripheral nervous system is, quite simply, everything else branch-like bundles of nerves that extend off through the skin, trunk, arms and hands, legs and feet.
All report back through the spinal chord to the brain in a huge sensory stream that is ready to transmit stimuli 24/7. Interestingly,
the eyes and ears are the only two organs that skip the main circuitry of the spinal chord to report directly to the brain. This is why
those who suffer spinal chord injuries are still able to see and hear.
Brain food? Use your head
A little common sense is all that is needed to keep both brain
and nerves functioning properly day to day, and just like any other organ requires equal amounts of proper rest and
Although the brain is primarily fueled by glucose (produced in the body by carbohydrates) this doesn't mean the brain and nervous system will benefit by lots of pretzels and sugary soft drinks.
Like most organs and tissues in our bodies, caring for them comes down in large part to eating a balanced diet with a range of protein, fats and carbs, (along with
recent research showing a beneficial effect of exercise
on the brain.)
