The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
Anatomically, your brain isn’t a muscle; although it contains a bit of muscle, it’s predominantly gray and white matter, with cellular structure and function far different (and more complex) than that of muscle. The human brain is capable of creating more ideas equivalent to that of the atoms of the universe. The human brain is made up of more than 10 billion nerve cells and over 50 billion other cells and weighs less than three pounds. The human brain is very soft like butter. Here are some amazing facts:
1. “Your brain generates about 12-25 watts of electricity. This is enough to power a low wattage LED light bulb.”
2. “Alcohol doesn’t make you forget anything. When you get blackout drunk, the brain temporarily loses the ability to create memories.”
3. “In raw data, our brains can compute 10 to the 13th and 10 to the 16th operations per second. This would be equal to more than one million times the people that there are on Earth. In essence and in theory, the human brain is capable of solving and computing problems much quicker than a computer.”
4. “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. The book Brain Rules explains how detrimental “multitasking” can be: Research shows your error rate goes up 50 percent and it takes you twice as long to do things.”
5. “When the mind recalls a memory, it’s not the original memory. In fact, the act of remembering is an act of creative re-imagination. The put-together memory doesn’t just have a few holes; it also has some entirely new bits pasted in.”
6. “Our brain usually chooses the first option on lists. Studies show when people are presented with a list of options they are most likely to pick whatever is first. The same is shown to hold true for voting.”
7. “The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. The left brain controls all the muscles on the right-hand side of the body; and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.”
8. “Our brain prefers images over text. Participants in studies only remember about 10% of information presented orally when they are tested 72 hours after instruction. However, that number jumps by about 65% when an image is added to the learning process.”
9. “Being able to access information quickly (e.g., on the Internet) makes you less likely to remember it. It’s great being able to access almost any piece of information in a few seconds, and resources such as Google, Wikipedia and YouTube have clearly been major parts of a revolution in how we find information. But studies suggest if the brain knows it can just access it again so easily, it’s less likely to bother remembering the information itself!”
10. “There is 2,500,000 gigabytes of storage space in your brain. The top-of-the-line iPhone 7 has 256.”
