With more than billion neurons (or: nerve cells) the human brain is one of the most important, interesting and complex organs in a human body. It is vital to keep your brain active and healthy because it helps us think, reason, remember, and learn new things. Our brain allows us to process and understand everything around us, but we are still very unaware of the fascinating functions of our brain. Here are 10 interesting facts about the human brain to blow your mind, and these facts are worth remembering!
1. We use 100% of our brain
It’s a myth that we only use 10% of your brain, we actually use all of it. Researchers confirm that our brain is always active, a lot of the brain is even active when we are sleeping or resting. Most of our brain is in use the most of the time, even when you perform a simple action. It varies from person to person which percentage of the brain is in use, it also depends on what you are doing or what you are thinking about. So this is one of the most important facts about the human brain: we use the full 100% of our brain.
2. Brain freeze
A brain freeze is a headache that arises when you eat or drink something very cold (like ice cream).
The brain freeze is caused because the palate has been in contact with a cold substance. This cold substance irritates the nerves, causing a rapid-onset headache. The pain is probably the result of contracting small blood vessels, but this pain usually goes away after a few seconds by pressing the tongue against the palate.
3. 60% of the brain is made of fat
Nearly sixty percent of the human brain is made of fat. Not only does that make it the fattiest organ in the human body, but these fat acids are crucial for your brain’s performance. The fat acids determine your brain’s ability to perform and the integrity. It is important to fuel the brain appropriately with the right intake of healthy, brain-boosting nutrients.
4. The human brain weighs 3 pounds
The one interesting fact among other facts about the human brain is that in terms of weight, the average adult human brain weighs in at 1300 to 1400 grams or around 3 pounds. For comparison, a new born human baby’s brain weighs approximately 350 to 400 grams or three-quarters of a pound. However, size does not always imply intelligence. Men tend to have bigger brains than women, a man’s brain is approximately 100 grams lager than the brain of a woman.
5. Your brain stops growing at 4 years old
On average, your spinal cord stops growing at 4 years old. Your spinal cord, which consists of a bundle of nervous tissue and support cells, is responsible for sending messages from your brain throughout your body.
6. Your brain isn’t fully formed until age 25
Brain development begins from the back of the brain and works its way to the front. The frontal lobes, which control planning and reasoning, are the last to strengthen and structure connections. What neuroscientists have found is that the brain starts shaping as young as seven and finishes about the age of 25. In any case, the brain seems to be complete by age 25. This varies between people based on age and other personal differences.
7. Alzheimer’s disease
Alzheimer’s disease is a brain disorder that is caused by a resistance to insulin in the brain, it starts gradually and gets worse. It is the cause of 60 to 70 percent of all cases of dementia. The most recognizable feature of the disease is the difficulty in remembering recent events. There are unfortunately no drugs to cure the disease or stop its progression, but some symptoms can be controlled.
8. 100 billion neurons
There are 100 billion neurons present in the human brain. The neuron (or: nerve/brain cells) is the core component of the nerve system in the brain. A neuron is an electric cell that processes and transmits information by signalling. Unlike other cells, neurons never divide, and they do not die off to be replaced by new ones. Each neuron can connect to up to 10,000 other neurons, passing signals and information to each other via as many as 1,000 trillion connections. This is one of the most interesting facts about the human brain.
9. More neurons during pregnancy
In early pregnancy, the neurons of the mother develop at an alarming rate of 250,000 per minute. This happens because the mother is developing the baby’s brain. The child will be born with 100 billion neurons forming connections with one another and creating an elaborate messaging network that scientists consider the most complex biological system in the world.
10. No new memories
As we grow older, we are unable to remember new things. According to the researchers in the US it is because the brain is unable to filter and remove old memories which prevent it from absorbing new ideas. So as we become older, we won’t have any new memories.
