The human brain is one of the most complex structures that poses cognitive abilities different from other creatures, consisting of billions of neurons. To the people unaware, the Human Brain, on average, weighs 1.5kg, which is much higher for a creature of our size. To our closest living relatives, Chimpanzees, their brain size is one-third of our own. Because billions of neurons communicate with the trillions of connections called synapses, our brain is one of our body’s most complicated and complex organs.

The Human Brain differs from other creatures.

  • Our brain Has sufficient memory to store the whole Internet.

It may sound surprising, but our brain’s storage capacity is so huge that it can store most of the Internet. Let’s put it into numbers: our brain’s storage capacity is 2.5 petabytes (1 petabyte = 1,048,576 GB). A human brain can compute 1018 operations per second; to put it in context, it’s about a billion billion calculations per second. Our brain works like a computer to be precise, better, and faster than a computer. As we know, computers use binary code (0 or 1) to understand real-world problems, while the human brain uses 26 types of code to understand them. The speed of transferring the information to the brain is 260 mph. 

  • The brain itself can’t feel pain.

Maybe it sounds a bit confusing, but it’s true that the human brain itself can’t feel any pain. That’s why brain surgeons may not require to give anesthesia to the patient during brain surgery. Now you may wonder, if the Brain can’t feel pain, why do we have a headache? Our brain doesn’t feel pain because it has no nociceptors in the brain tissue. But our brain is surrounded by the layers of covering and blood vessels that contain pain receptors. 

  • The human brain is so Greedy.

The human brain constitutes only 3% of our body’s total weight, but it receives one-third of the energy produced by our body and approximately thirty percent of blood pumped by our heart. This shows how much support it needs to work appropriately in comparison with the other vital parts of our body. Some scientists define the brain as the naughty child of the house who is mischievous and demanding, but at the same time, it is smart and efficient. Our brain needs a lot of energy and a constant supply of oxygen to work efficiently, but it can’t store energy like other muscles, which can store energy in the form of carbohydrates.

  • Your brain is as unique as Our Fingerprints.

Every individual has a unique fingerprint. As two people can not have the same fingerprint, it makes the go-to method for govt, security agencies, and immigration authorities. But what about the Nervous System or the central processing unit inside our head? Is it possible to identify the brain’s identity using certain anatomical features? And the answer is yes, like the fingerprint, and no two people can have the same brain anatomy research have shown published by the University of Zurich. This uniqueness is a result of some genetic factors and individual life experiences. 


Undoubtedly the human brain is the most complex organ in the human body and one of the most complicated structures in the universe. As we have heard, great power comes with great responsibility. Our brain needs proper nutrition and proper care. It is necessary to keep our brains healthy and active.
