Psychology facts about mind 

1. 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.

 2. The human brain begins to lose some memory abilities as well as some cognitive skills by your late 20s.

 3. The human brain gets smaller as we get older. This usually happens sometime after middle age.

 4. Surgical removal of almost half our brain is possible with little or no effect on personality or memory



These brain facts might sound crazy, but a hemispherectomy, or the surgical removal of half of the brain, can and does happen. It’s a very rare neurosurgical procedure that is used to treat a variety of seizure disorders. However, this type of procedure, as one would imagine, is not done without impact. “Some traits are very specific to one hemisphere, thus it can give us very subtle differences,” says Brock. “Usually memory, humor, and personality will recover, but cognition might change a little.

5. Short-term memory generally lasts around 20 to 30 seconds


Ever wonder how you can say something, get distracted briefly, and then completely forget what you were about to say? This has to do with your brain’s capacity for holding small amounts of information in the active mind. It keeps that information in an available state for easy access, but only does so for a period of around a half a minute. Brock notes that when recalling numbers, specifically, most people hold the memory for around 7.3 seconds on the average and 9.3 seconds on average for letters. Here are some more everyday things you didn’t realize were tricking your brain.

6. Your brain’s storage  is virtually unlimited


There’s no such thing as knowing too much—or learning so much that you can’t retain any more information (though it can certainly feel that way after sitting through a long board meeting). “Your brain doesn’t get ‘used up’ like the data storage in your computer or smartphone,” says Dr. Krieff. There is endless brain power! Although lack of sleep can affect your brain’s ability to create more memories.

7. Dinosaurs lacked the ability to think and reason


There’s plenty that scientists are still discovering about the long-lost reptiles that roamed the earth 65 million years ago. But what they do know is that dinosaurs couldn’t think or reason the way humans can. “Dinosaurs had no neocortex, which we use for thinking and such, and no frontal lobes, which we use for planning and problem-solving and the like,” says Soper. “Dinosaur thinking is more along the lines of chicken thinking: They could learn certain things, but minimally compared to mammals.” They did, however, have a killer sense of smell that was far, far better than we humans have. Here’s how humans can sharpen their sense of taste and smell.

8. The harder your brain is working, the smaller your brain waves


As it’s working, your brain is creating electric fields. “The fields are measured on your scalp, called the electroencephalogram (EEG), and are often larger when your brain is doing less,” explains Wingeier. “This is because idle neurons sync up by default—so like a crowd chanting in unison, they can be ‘heard’ from far away.” Neurons processing more information sync up in more complex patterns, so like a crowd in which people are having a thousand different conversations, they’re harder to “hear” clearly.

9. The brain has more cell types than any other tissue in our body


Unlike the liver or certain muscles in our body where most of the cells are the same type, the brain is composed of a variety of complicated, interconnected types of cells, one being neurons, explains Hermona Soreq, PhD, professor of molecular neuroscience at the Hebrew University of Jerusalem’s Edmond and Lily Safra Center for Brain Sciences.

10. The brain itself can’t feel pain and love 


Ever wonder how brain surgeons are able to perform surgeries on patients while they’re awake? Beth McQuiston, MD, a neurologist and the medical director of the diagnostics division at the health-care company Abbott, explains that even though the brain has 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. Don’t miss these 16 signs your headache pain could actually be something worse.


11. The brain of a human contains approximately one hundred billion neurons IDEAS.

12.  It is a myth that humans only use 10 percent of our brain. We actually use all of it. We’re even using more than 10 percent when we sleep.

13. Cholesterol is key to learning and memory. However, high cholesterol has different effects depending on your age and other factors.

14. A man by the name of Bruce Bridgeman spent nearly his entire life, 67 years, without the ability of depth perception, called stereoblindness. However, after being forced to purchase 3D glasses to watch the movie Hugo in theaters, his brain clicked and he was able to experience 3D vision.


15. A man in the UK had chronic hiccups for 2.5 years of his life and was told that it was likely caused by heartburn. After a Japanese TV show picked up the strange phenomena and paid for medical testing, a brain tumor was discovered. Once the man had the tumor removed, his chronic hiccups went away for good.

16. Blacking out from drinking is actually caused by the effect of alcohol on the hippocampus, the part of your brain responsible for memory. You’re not physically forgetting anything, rather your brain becomes incapable of storing and recording new memories.
