How does the human brain

The human brain weighs approximately from 1020 to 1970. The brain of men weighs a little more than the brain of the beautiful half of humanity. Despite the fact that the brain is absolutely not sensitive to pain, it consists of a great variety of nerve cells that are interconnected. The brain consists of the essential five divisions - the forebrain (left and right hemispheres), the main medulla, the posterior (the bridge and the cerebellum), the mid and diencephalon. All these departments are combined into three large parts: the two hemispheres of the large brain, the active cerebellum and the dominant brainstem.

The most important cerebral hemispheres


The left and right hemispheres are like two completely different poles. One hemisphere (left) specializes in logical and abstract thinking. The second hemisphere (right) is engaged in concrete and figurative thinking. Scientists have shown that a person whose left hemisphere predominates in his work has a more optimistic attitude and always a good mood. The big hemispheres account for about 70% of the entire brain mass.The left and right hemisphere consists of the frontal, temporal, parietal and occipital parts. In the frontal part, there are processes responsible for motor activity. The parietal zone is responsible for bodily sensations. The temporal portions are the areas of the brain that are responsible for hearing, speech, and memory, and the back of the head is responsible for seeing.

Cerebellum, without which full work anywhere


The cerebellum is a no less significant part of the brain, thanks to the work of which a person can feel excellent when in a vertical state. The cerebellum is located under the occipital lobes of the left and right hemispheres. The cerebellum helps a person to form all the skills that are necessary for a full daily life. So, the main functions of the cerebellum are in flawless coordination of movements and the most important distribution of muscle tone. The cerebellum weighs approximately 120-150 g.

Brain stem. What is the problem?


The brain stem is a direct continuation of the spinal cord. Looks like a brain stem extended education. This part includes the medulla, pons, and the midbrain. Many scientists also include the cerebellum, reticular formation, thalamus and hypothalamus in this zone.The brain stem controls involuntary behavior (coughing, sneezing and other processes), as well as behavior that is under arbitrary control (breathing, sleep, eating, etc.).
