What is the most surprising thing about the human brain?
Our brain is the most complex organ in the body. In addition to controlling basic life functions such as breathing, organ function, and exercise, it is behind all the complex processes of thought, action and emotion control, memory-making. However, despite how important our brains are, many still know very little about it.
This is your brain.
1. Always active
The brain is always active, even when we are sleeping. We need to keep us alive. However, different parts of the brain are responsible for different functions. The brain is divided into lobes of XNUMX pairs on either side of the head. As such, it is located in front of the frontal lobe head and just below the temporal lobe. It is located in the middle of the parietal lobe, located behind the head of the occipital lobe.
The frontal lobe is often associated with “making us human”. It is involved in cognitive processes such as reasoning, learning, creativity, attention and muscle control used in exercise and speech. It also creates memories and regulates emotions and actions.
The parietal lobe is involved in the mixing of functions. This includes processing as well as virtual space information necessary for the movement and depth perception and exploration of senses and figures. The temporal lobe is also a memory process as well as information related to sound, including the language we hear. The occipital lobe is involved in visual processing. When light enters the eye, it is transmitted by nerves to this area, which translates into a “seeing” image.
The lobe is further divided into functional areas. These are individual areas of a specific lobe that are responsible for specific functions. For example, the area of the frontal lobe is particularly concerned with language production and understanding in the Broca region.
By Scanning the Brain Scientists can determine which areas are experiencing increased blood flow and measure when and where they are more active in the brain by providing the extra oxygen they need to function or perform their tasks. Knowing which parts perform what tasks are important when conducting research and surgery.
2. We are constantly receiving information
The brain is constantly receiving information. This information is controlled by two paths that check all paths. Sensory information is flowing into the brain. Motor information is flowing out of it.
The brain always receives this information, but often does not know the information going to the area of the brain that processes “unconscious” information. For example, information about the location of muscles and joints is always sent to the brain-but we rarely notice it until it becomes uncomfortable or needs to be repositioned.
But when it comes to outgoing motor information, including spontaneous actions we control, like picking up something, we know its function. However, like sensory information, motor movements, such as exercise or breathing, can occur unconsciously, such as the muscles that move food through the gastrointestinal system.
3. About 20% of the body's blood goes to the brain.
As with all living tissues, oxygen must be supplied from the blood to maintain brain function. The brain receives 15-20% blood from the resting heart. Many factors can include age, gender, and weight. For an average man, about 70 milliliters of blood pumps are spinning around the heart rate. Thus, about 14 milliliters is delivered to the brain per heart rate, which is essential to supply oxygen to brain cells.
It is well known that more strokes occur where blood supply to the brain is stopped. Of the left brain. This is important because the right side of the brain controls the left side of the body and vice versa. Researchers may influence the function of the left-right hand of the brain-the right-hand handle is more likely to suffer loss of function after a stroke.
4. Brain surgery doesn't hurt

While this seems bizarre, being awake during brain surgery is actually more common than people think. Surgery, often associated with the “functional” areas of the brain (areas responsible for movement, speech, or vision) must be awakened to assess these functions as the surgery progresses after the patient is placed under general anesthesia.
Surprisingly, actual surgery does not harm the brain at all. This is because the brain has no special pain receptors nociceptors. The only painful part of the operation is the skin, skull, and meninges (layers of connective tissue that protect the brain). Depending on several factors, the patient may have a general or local anesthetic for this part of the procedure.
5. Brain damage can change who we are
Much of what we know about the brain comes from what's going wrong. One of the most famous examples is Phineas Gage. He was known as a responsible and straightforward worker. However, in an accident at work, as the metal rod passed through the skull, the frontal lobe was damaged, turning childish, rude, and impulsive. Gage explained to scientists in the 19th century that frontal lobe damage can cause serious personality changes.
We also show that people who have lost their eyesight after the occipital lobe has been damaged by trauma, tumor growth, or stroke are still “blind”.This shows that not all visual information goes into the visual cortex of the occipital lobe. Despite still losing sight information and navigating around obstacles, despite sight loss. Some people can “see” some emotions and report how they are described and make them feel. This shows how high the interconnected brain function is given.
Researchers know a lot about the brain and its functions, but we have a lot to learn. We have not yet studied what some areas of the brain do and how they communicate with other parts of the organ.
