Prepare for a brain explosion
The brain is one of the most astonishing and intricate parts of the human body, yet it only takes up a fraction of space. But, oddly enough, there’s so much the average person doesn’t know about his or her noggin. Here are some strangely interesting facts about your grey matter.
The brain itself can’t feel pain
Ever wonder how brain surgeons are able to perform surgeries on patients while they’re awake? Beth McQuiston, MD, neurologist and medical director at Abbott, explains that even though the brain contains layers of coverings and blood vessels that contain pain receptors, the brain itself has zero. When a person has a headache, for example, it’s often thought of as pain stemming from the brain, but this is actually not the case. The muscles and skin surrounding the brain, however, can feel pain.
Your brain is greedy
Your brain might account for only about 3 percent of your body weight, but it receives about 30 percent of the blood being pumped by your heart. This shows how much attention and support it requires in comparison to the other seemingly important areas of your body. “The brain is like a spoiled and demanding child, but yet it is extremely smart and efficient,” explains Bennet Omalu, MD, a forensic pathologist, neuropathologist, epidemiologist, clinical professor at University of California, Davis and author of Truth Doesn’t Have a Side. “It takes the brain about 1/10,000th of a second to respond to something and generate an action.”
