Why is our brain divided into two hemispheres? Don't rush to the answer: "The left side of the brain is responsible for logic and the right side is responsible for emotions. This is only partially true. We cannot speak about absolute domination of one of hemispheres in logic or emotions. The two halves of the brain are practically identical in structure, and for this reason we can only speak of relative superiority. A more practical and long time scientifically proven reason for the division of the brain is as follows👇🏻 The right hemisphere is responsible for movement and sensitivity of the left half of the body, the left hemisphere for the right half. The "halves" are united by the corpus callosum, which builds associative connections between the hemispheres.
