Amazing Facts and Myths about Brain
The Brain of a human contains approximately one hundred billion neurons.
It is a myth that humans only use 10 percent of our brains. We actually use all of it. We’re even using more than 10 percent when we sleep.
Cholesterol is a key to learning and memory. However, high cholesterol has different effects depending on your age and other factors.
Information runs between neurons in your brain for everything we see, think, or do. These neurons move information at different speeds. The fastest speed for information to pass between neurons is about 250 mph.
Dreams are believed to be a combination of imagination, physiological factors, and neurological factors. They prove that your brain is working even when you are sleeping.
The brain can’t feel pain. It interprets pain signals sent to it, but it does not feel pain.
The human brain gets smaller as we get older. This usually happens sometime after middle age.
During the mummification process, Egyptians would usually remove the brains through the nose.
Alcohol affects your brain in ways that include blurred vision, slurred speaking, an unsteady walk, and more. These usually disappear once you become sober again. However, if you drink often for long periods of time, there is evidence that alcohol can affect your brain permanently and not reverse once you become sober again. Long term effects include memory issues and some reduced cognitive function.
Your brain uses 20 percent of the oxygen and blood in your body.
When the blood supply to the brain stops, it is almost after 8-10 seconds that the brain starts losing consciousness.
The brain is capable of surviving for 5 to 6 minutes only if it doesn’t get oxygen after which it dies. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable. At 15 minutes, survival becomes nearly impossible.
‘Your Brain Works Better Under Pressure’ is a Myth. The theory is a widely popular one, but in reality, your mind is not working better under pressure, you are just more focused on the task.
‘Your IQ stays the same throughout your life’ is also a Myth. Research has shown that your IQ can fluctuate while you age, but it’s important to note that testing someone’s intelligence is an imperfect science. Fluid intelligence, or the ability to think quickly and recall information, peaks at the age of 18 and then tapers off as you get older. Conversely, someone’s emotional intelligence can continue to improve until the age of 30.
The brain makes up about 2 percent of a human's body weight.
Multitasking is actually impossible. When we think we're multitasking, we're actually context-switching. That is, we're quickly switching back-and-forth between different tasks, rather than doing them at the same time.
