21 Things You Didn’t Know About Your Brain
The human brain is a fascinating, complex mystery. For centuries, scientists and philosophers have been intrigued by the brain and, until recently, considered the brain nearly incomprehensible.
Now, the brain is revealing many of its deep, dark secrets. Scientists have learned more about the brain in the last 10 years than in all previous centuries, mostly because of warp-speed research.
The brain is the center of intelligence. It’s the interpreter of the senses, the trigger of body movements, and the control center of behavior. The human brain with all its complexity acts like a storage device which safety holds a person’s most cherished memories. A person’s personality is unarguably influenced by the brain, as well as generations of human consciousness. It’s what gives gives a person passion, motion and emotion. The brain is a command center for the central nervous system, and it imbues us with our physical and cognitive abilities.
Here are 21 things you didn’t know about your brain:
1. It Can’t Feel Pain
The human brain is the only organ in the human body that lacks nerves, despite that it acts as the central command for the central nervous system. The human brain feels no pain, which is why patients are often kept fully awake during brain surgeries.
2. It’s an Energy Hog
The human brain consumes the largest portion of the total energy that is generated by the human body. The brain consumes 20 percent of our energy despite the fact that it only represents 2 percent of the body’s total weight. The energy is vital for maintaining healthy brain cells and fueling nerve impulses.
3. It’s Surprisingly Squishy
The human brain is not solid. It is soft and squishy, similar to the consistency of soft tofu or soft gelatin. And it’s very fragile.
It makes sense that it’s so squishy — the brain is 73 percent water. It takes only 2 percent dehydration to affect the brain’s attention, memory and other cognitive skills. The brain weighs about three pounds. Of that, the dry weight is 60 percent fat, making the brain the body’s undisputedly fattiest organ – and explaining some of the squishiness.
