Brains Unknown Facts Can Surprise You.
Brains are the most complex organ in the human body. It controls some essential functions in our body, like movement, breathing, and organ functions. But there are some other unknown facts and features the brain runs, and we do not have any clue on them. Besides its regular jobs, the brain does some complex processes, including our thought, how we control emotions and behavior, and creating memories.
Let's have a look at some surprising facts of our brain.
The brain is active always
If the brain sleeps too when we are sleeping, then we will die. So, brains remain active even though we sleep. There are four pairs of lobes with different parts in our brain doing different functions.
Temporal lobes lie under the frontal lobes that locate the fronter part of our head. Then comes parietal lobes in the middle and the occipital lobes in the back part of our head.
The frontal lobe works on learning, attention, reasoning, creativity, and controlling muscles. Then it also assists us in making memories. Besides, it helps in regulating behavior and emotions.
While the parietal lobes help in numerical and sensory processing, the job of the temporal lobes is to receive sound-related information, including the language we talk and hear. The occipital lobes do some works for which we can see.
The lobes are then divided into several other parts, and each section is capable of doing their individual responsibility. For example, we can mention Broca's area, an area located in the frontal lobe. This particular area works in language production and comprehension. For researching and performing surgery, scientists scan the brains to see where blood flow in particular brain parts increases. This blood flow supplies the required oxygen to function.
Information receiver without rest
Brains are always receiving information, and they do this by using two pathways; sensory information and motor information. The first one flows information into the brain, and then the next one flows information out.
For receiving information, the brain is always active. We remain unaware of this because the brain does this storing work in the form of "unconscious" information. Our body position and muscle position's information is in the brain always, but we do not notice this until we need any adjust those positions.
But the motor information is an outgoing one, and we already know about what is going to do like picking something up.
The brain needs 20% blood flow from our body.
Our brain works by using the blood flow from our heart. The brain needs oxygen, as we mentioned before, and it gets oxygen from the blood. 15-20 blood from the heart goes to the brain, and the amount may fluctuate depending on age, weight, and gender.
One heartbeat in males produces 70 milliliters of blood pump through the body, and the brain receives 14 milliliters for the required oxygen.
When the blood supply in our brains gets interrupted, it causes a stroke on the left side of the brain. We know that the remaining part controls the right part of our body, and the right part controls the left part of our body. So, strokes are very dangerous to right-handed people.
Surgery in the brain without pain
Recently, a video went viral in which we see a woman playing the violin, and doctors are performing brain surgery on that lady. It may seem bizarre to us that how the woman is so normal while a part of her is being cut down. Well, it is normal.
Before completing surgery on the brain's functional areas, patients need general anesthetic because otherwise, those functions will stop like vision, speech, or movement. So, the patients get anesthetic and then awake after the surgery.
But it is a surprising fact that the brain doesn't have nociceptors, a specialized pain receptor. So, any surgery in the brain does not hurt. But, as the skin, skull, and meninges have pain receptors, these areas need anaesthetic processes, whether local or general.
Personality change for brain damage
Any damage to our brain can change our personality. The famous case of Phineas Gage highlights that. He was a rail worker. In an accident, a rod went through his skull. This damage transformed him into a disrespectful, childish, and impulsive personality who was an upstanding and responsible worker before the tragedy. The loss in his frontal lobe changed his life.
Similarly, any damage in the occipital lobe can damage their vision. This damage in that lobe may occur from stroke, tumor growth, or trauma. Some of them can have "blindsight" that helps with some aspects of sight.
