15 Facts About the Human Brain These Unusual Facts Are Worth Remembering
The brain is a very complex part of your body. It has the ability to send and receive a large amount of information. Because of this, there are still many mysteries about the human brain. Here are some quick facts to help you understand the most complicated organ in your body.
1-There’s a virus that attacks human DNA making people less intelligent, impairing brain activity, learning and memory.
2-Stress can change the size of your brain and make it smaller.
3-Alcohol doesn’t make you forget anything. When you get blackout drunk, the brain temporarily loses the ability to create memories.
4-Memories start forming in the womb.Memories start forming in the womb, as this is a critical time for brain development. Memory recall can occur as early as four months into pregnancy.
5-Frequent jet lag can damage memory. Stress hormones released during jet lag can damage the temporal lobe and memory.
6-Due to the new discovery of many brain parasites, scientist now think a Zombie Apocalypse is actually possible.
7-Sweating can temporarily shrink the brain.An hour and a half of sweating can temporarily shrink brain size as much as one year of aging does.
8-Headaches are caused by a chemical reaction.Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. Serotonin is a chemical necessary for communication between nerve cells. When serotonin or estrogen levels change, the result for some is a headache or migraine. Serotonin levels may affect both sexes, while fluctuating estrogen levels affect women only.
9-Feeling tired? Go ahead and yawn. Yawning cools down the brain, research suggests. Sleep deprivation raises brain temperature.
10-Cholesterol is key to learning and memory.The brain has a higher cholesterol content than any other organ. In fact, about 25% of the body’s cholesterol resides within the brain. The brain is highly dependent on cholesterol, but its cholesterol metabolism is unique. Because the blood-brain barrier prevents brain cells from taking up cholesterol from the blood, the brain must produce its own cholesterol. The brain’s cholesterol is much more stable than the cholesterol in other organs, but when it breaks down, it is recycled into new cholesterol right in the brain.
11-There is no Left Brain/Right Brain Divide. It’s a myth. They work together.
12-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.
13- There are about 100 billion neurons in a human brain, which is about the same as the number of stars in the Milky Way galaxy.
14.Most scientists argue that there is no evidence that playing classical music to babies increases the power of their mind. However, children who learn to play a musical instrument can develop their mental skills further than those who don’t learn a musical instrument.
