The brain is part of the central nervous system of our body. It is the hardest part of him. It has the ability to send and receive an enormous amount of information, and due to its complexity, there are some things that doctors and scientists still do not fully understand. This also means that you are likely to come across a lot of surprising facts that you may not know about your brain.
For example, what exactly is a brain freeze? Specifically, it is a sphenopalatine ganglioneuralgia . It happens when something you eat or drink is very cold. This cools the blood vessels and arteries in the back of the throat, including those that carry blood to the brain. They contract when they are cold and reopen when they are warm again, causing pain in the forehead. A cold stimulus headache.
Another curiosity. Alcohol affects the brain in ways that cause blurred vision, slurred speech, unsteady walking, and much more. These effects generally go away once we are sober again. However, if you drink frequently for long periods of time, there is evidence that alcohol can permanently affect the brain and not reverse itself once we are sober again. Long-term effects include memory problems and a reduction in some cognitive functions.
Did you know that the outermost layer of the brain is the cerebral cortex? It consists of four lobes: frontal, parietal, temporal and occipital.
Information flows between neurons in the brain with everything we see, think, or do. These neurons move information at different speeds. The fastest speed of data passing between neurons is approximately 400 km / h.
More curiosities about the human brain:
- The human brain is the largest brain of all vertebrates in relation to body size
- It weighs about 1.5 kilograms.
- The average man has a brain volume of 1,274 cubic centimeters.
- The average female brain has a volume of 1,131 cm3.
- The brain makes up about 2 percent of a human’s body weight.
- The brain accounts for 85 percent of the brain’s weight.
- It contains about 86 billion nerve cells (neurons), the “gray matter.”
- It contains billions of nerve fibers (axons and dendrites), the “white matter.”
- These neurons are connected by trillions of connections or synapses.
We have about 100,000 million neurons and 1,400 new neurons are generated every day despite the fact that as we age, their number decreases .
