The human brain is a truly fascinating organ, and there are many intriguing facts about it that might not be widely known. Here are some of the most interesting facts about the brain:
Only gain, no pain. The brain itself does not have pain receptors, so it cannot feel pain. That's why brain surgery can be performed while the patient is awake.
We often associate dreaming with deep sleep, but the most vivid dreams usually occur during a phase of sleep known as Rapid Eye Movement (REM) sleep.
It's estimated that the human brain's storage capacity is equivalent to about 2.5 petabytes, or a million gigabytes, which is roughly 10-20 million times the storage capacity of a typical computer.
The human brain is incredibly efficient. It can perform about 38 thousand trillion operations per second, which is more than 10 times the processing power of the world's most powerful supercomputer.
The brain represents only about 2% of an individual's total body weight, yet it consumes around 20% of the body's energy.
