Why Understanding Brain Facts Matters in Biology
The brain is a part of our body’s central nervous system. It is the most complicated part of the human body. Brain has the ability for sending and receiving a huge amount of information. Since it is so complex, there are a few things that the doctors and the scientists do not completely understand about it yet. This means that there are some interesting brain facts that you may not know about your own brain. Your brains allow you to process the world, to understand everything around you, learn about the new things, and paradoxically, it is still unclear of how much of your own brain functions. However, the modern neuroscience and the cognitive sciences have made some great strides for understanding the effect your brain has on your everyday functions. In this article, we will look at some interesting facts about the human brain. These amazing facts about brain also include the psychological facts about the human brain.

Interesting Facts About the Brain
Let us take a look at some interesting facts about the human brain. The amazing facts about the human brain include the following:
20 Facts About The Brain
Signs of the successful brain surgeries are dated as far back as during the Stone Age.
An adult brain has a weight of around 3 pounds.
Around 75 per cent of the brain is made of water. This signifies that dehydration, even in smaller amounts, has a greater negative effect on the functions of the brain.
The largest-sized brain of any animal on the earth is that of the sperm whale. It has a weight of about 20 pounds.
The human brain tends to grow three times than its size during the first year of life. It continues to grow until you grow around 18 years old.
Headaches are generally caused due to the chemical reaction that occurs in your brain and is combined with the muscles and the nerves of your neck and the head.
The human brain consists of roughly one hundred billion neurons.
It is totally a myth that humans only use 10 per cent of their brain. Humans tend to actually use all of it. We are using even more than 10 per cent of the brain when we are sleeping.
Cholesterol is known to be the key to learning and memory. However, higher-level of cholesterol has totally different effects which depend on your age and several other factors.
Information keeps running between the neurons in your brain for every activity including everything you see, think, and do. These neurons move the information at varying speeds. The fastest speed for the information to pass between two different neurons is known to be about 250 mph.
Dreams are known to be the combination of your imagination, several physiological factors, and several neurological factors. Dreams prove that your brain works even when you are asleep.
The phantom limb pain syndrome occurs when the central nervous system, that includes your brain, starts to feel the pain of any limb which has been amputated.
Your brain cannot feel any pain. It interprets the pain signals that are sent to it, but it does not feel any kind of pain.
A brain freeze is actually a sphenopalatine ganglion neuralgia. It happens if you eat or drink which is cold. It tends to chill the blood vessels and the arteries in the very back of the throat, that includes the ones which take the blood to your brain. These vessels constrict when they are cold and then open back up when they are warm again, and this causes the pain in your forehead.
The human brain starts to lose some of its memory abilities and some of the cognitive skills during your late 20s.
The human brain starts to get smaller as you get older. This generally happens after the middle age.
During the time of the mummification process, the Egyptians would generally remove the brains via the nose.
Alcohol affects your brain in different ways which include blurry vision, slurred speaking, an unsteady walk, and much more. These symptoms generally disappear once you are sober again. However, if you are drinking often for longer periods of time, there is a piece of evidence which says that alcohol can have an effect on your brain permanently and cannot be reversed even once you are sober again. The long term effects include the memory issues and a reduced cognitive function.
The eyewitness accounts of the criminal suspects are generally only around 50 per cent accurate since it is a bit difficult for your brain to remember the details of a person you are not familiar with. The traumatic events can also have an effect on the brain’s ability to remember the details.
Your brain uses around 20 per cent of the oxygen and the blood from your body.
FAQs on 25 Fascinating Facts About the Brain
1. What is the main function of the human brain?
The brain acts as the command centre for the entire body. Its primary function is to receive information from our senses (like sight and sound), process this information, and then generate responses. It controls our thoughts, memory, speech, movement of our arms and legs, and the function of many organs within our body.
2. What is the human brain mostly made of?
Although it feels firm, the brain is surprisingly soft and is composed of about 75-80% water. The remaining part consists of fats and proteins. This high water content is crucial for maintaining brain health and function, which is why staying hydrated is so important for concentration and thinking clearly.
3. What are some surprising facts about the brain?
The brain is full of amazing characteristics. Here are a few interesting facts:
- It generates about 23 watts of power when you are awake, which is enough to power a small lightbulb.
- The brain continues to develop until you are in your mid-20s.
- Your brain is more active when you are asleep than when you are awake.
- Information can travel through different types of neurons at speeds of up to 268 miles per hour.
- It has a massive storage capacity, estimated to be equivalent to more than four terabytes on a hard drive.
4. Is it true that humans only use 10% of their brain?
This is a popular myth, but it is completely false. Brain imaging studies, like fMRI and PET scans, clearly show that we use virtually every part of the brain. Most of the brain is active nearly all the time, even when we are resting or sleeping. Different tasks just activate different regions more intensely.
5. If the brain processes pain signals, why can't it feel pain itself?
This is a fascinating aspect of biology. The brain is the organ that interprets the pain signals sent from the rest of the body, allowing you to feel a cut on your finger or a headache. However, the brain tissue itself does not have any pain receptors (nociceptors). This is why surgeons can perform brain surgery on an awake patient without causing them any pain in the brain.
6. How do the left and right sides of the brain work together?
While it's true that some functions are more dominant on one side (e.g., language often on the left, spatial awareness on the right), the idea of being purely 'left-brained' or 'right-brained' is a simplification. The two hemispheres are connected by a thick bundle of nerves called the corpus callosum and are in constant communication. For almost every complex task, from solving a math problem to painting, both sides work together as an integrated team.
7. Is any one part of the brain more important than the others?
No single part of the brain is considered more important, as they all work together in a complex, interconnected network. Each region has specialised functions that are vital for our survival and daily activities. For example, the cerebrum controls higher functions like thought, the cerebellum coordinates balance and movement, and the brainstem manages essential life functions like breathing and heartbeat. All are critical.
