We all know, that brain is one of the most important things that we have
in our body. Without brain we won’t be able to breath and live. The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localized nerve nets are instead of brain.These are facts that are well known, but what about the tings that are not so well known?
These brain facts dispel many brain myths that linger from the past. Learn how the brain works, for better (or worse). All facts have original references.
The study of the human brain has been called the last frontier in science.
The field of neuroscience is still in its infancy, but is rapidly exploding — turning yesterday’s brain “facts” into today’s brain “myths.”
Experts agree there is more we don’t know about the brain than we currently know.
Here are some of the fascinating facts and figures about the human brain.
1. The typical brain is about 2% of a body’s weight but uses 20% of its total energy and oxygen intake.
2. Your brain is 73% water. It takes only 2% dehydration to affect your attention, memory and other cognitive skills.
3. Ninety minutes of sweating can temporarily shrink the brain as much as one year of aging.
4. Your brain weighs about 3 pounds. Of that, the dry weight is 60% fat, making your brain the fattiest organ.
5. Twenty-five percent of the body’s cholesterol resides within the brain. Cholesterol is an integral part of every brain cell. Without adequate cholesterol, brain cells die.
6. No one knows for sure, but the latest estimate is that our brains contain roughly 86 billion brain cells.
7. Each neuron connects with, on average, 40,000 synapses.
8. A piece of brain tissue the size of a grain of sand contains 100,000 neurons and 1 billion synapses all communicating with each other.
