Importance of Brain

When the ancient egyptians embalmed their dead pharaohs and priests to prepare them for the afterlife, they carefully processed the heart and put it back into the body, and the brain was thrown away. A hollow tube was inserted into the nose, the brains were shaken, and then they were sucked out through this tube. The brain was viewed as a waste product. It took a long time before people finally realized that the brain is the main thing that they have. Some works written before our era talk about the connection of the brain with functions such as movement and thinking. Nevertheless, it was only after a few thousand years that the understanding that our "i" is in the brain became generally accepted. For example, aristotle and other great philosophers believed that the brain is an organ of minor importance, and the soul is located in the heart. And only in the middle of the 17th century - from the time when the ancient egyptians mummified the pharaohs, turning them into zombies, millennia passed - the french philosopher rene descartes established that the location of the soul is in the brain. Almost all brain structures are located symmetrically about the central line, for example we have the left and right hemispheres of the brain with the left and right frontal lobes
