Brain – Fascinating Facts
FASCINATING FACTS REVEALED ABOUT THE BODY’S AMAZING ORGAN
The brain is the essence of the individual. Alive, changing and full of energy, this essential organ enables humans to do what they do and to be who they are. Everyone’s brain is different.
Now, a breakthrough exhibit welcomes people of all ages to explore the mechanics and mystique of the body’s amazing organ in “BRAIN: The World Inside Your Head,” which premiered at the Arts and Industries Building at the Smithsonian Institution in Washington, D.C.
Hands-on, total sensory displays immerse visitors in the brain’s physiology, psychology and mystery in “BRAIN,” made possible by Pfizer. Children and adults can virtually walk through this amazing organ – a giant model of the brain shows how electrical impulses traveling throughout the body handle our every move, process and thought. Another section shares the history of exploration and understanding of the brain. Throughout the exhibit, “Brain Bytes” point to amazing facts about the body’s mainframe. For example, visitors see that:
– The brain is the most complex structure in the known universe.
– The brain contains as many neurons as there are stars in the Milky Way.
– Electrical messages in neurons travel about 220 miles per hour – that’s about 323 feet per second!
– It’s commonly thought that you use only 10 percent of your brain. Not so! You may not use every neuron in your brain at the same time, but each is important.
– A piece of a brain the size of a grain of sand contains 100,000 neurons and 1 billion synapses, all “talking” to one another.
– The brain never turns off or even rests through your entire life.
– While the brain makes up only 2 percent of body weight, it uses 20 percent of the body’s fuel.
– By age 4, the brain has grown to its full size.
– By age 5, the brain has gained almost its full weight.
– Childhood years are the best time to develop strong math, logic, and musical skills.
– During childhood years the brain can rewire itself to make up for many defects and injury.
– Although the brain registers pain from the rest of the body, it can’t feel pain itself. There are no pain sensors inside the brain. Surgeons can operate on the brain while a patient is fully awake.
