The human brain, which weighs approximately 3 pounds, is an incredible organ. In spite of scientific advancement, there is still so much we don’t know or understand about the human brain. The things that are known about the brain, however, are truly amazing. The following are 12 facts you may not know about the human brain.
1. Dieting Could Cause Your Brain to Eat Itself
Just like other parts of the body, the brain will actually begin to eat itself to keep from starving. Tests that were conducted on mice have shown that hunger causes a process called autophagy to occur. While this is happening fatty acids cause specific neurons to be produced that intensify hunger signals. This could be one reason the best way to lose weight involves simply eating healthy and exercising. This research could make a person think twice before beginning an extreme diet.
2. The Brain Produces Enough Electricity to Power a Light Bulb
When awake, the human brain can produce enough electricity to power a small light bulb. This electric output is equal to approximately 25 to 35 watts. This power comes from the fact that the brain contains approximately 100 billion neurons. These neurons are the pathways for electrical and chemical signals that enable us to laugh, dream, see, move, and simply think. One neuron may not generate much electricity but all of them working at one time produce enough power to light up a light bulb.
3. You Could Survive on Half a Brain
Due to injury or disease, some people have had large portions of their brain removed. It’s even possible to have half of your brain removed by surgery with no apparent effect on memory or personality. There is a documented case of a little girl having half her brain removed to prevent severe seizures from taking place. The brain is so dynamic that it has the ability to adjust even in extreme situations such as this. When part of the brain is removed the part that is left has the ability to relearn many skills that may have been lost. The remaining parts of the brain simply take over the functions that were being completed by the part that is missing.
4. The Brain Reacts to Alcohol in 6 Minutes
The old saying that alcohol can quickly go to your head seems to be true and based on science. Brain cells will start reacting to alcohol within 6 minutes. The alcohol, however, doesn’t make you forget anything. If you drink to the point that you blackout, the brain only temporarily loses the ability to create memories. While science has proven many differences between men and women, how alcohol affects the brain doesn’t appear to be one of them. The brains of both males and females in the study reacted to the alcohol in the same way.
