Over time, various myths have emerged about the brain, many of which have been perpetuated, so that they have almost become ingrained in the common mind. As we study the brain in more depth, scientists have demolished many of these myths.
The brain weighs approximately 1,400 grams, and with the help of its many cells, it transmits and receives messages from different parts of the body. Although it represents only 2% of the total body weight, this organ is a big consumer of energy. Thus, it consumes about 20% of the total energy of the body.
The brain is one of the best-protected organs. Protection is provided by the cerebrospinal fluid in which it is “bathed”. This colorless substance protects the brain, for example, in the event of sudden body movements.

What are the roles of the two cerebral hemispheres
The brain has two cerebral hemispheres, the right, and the left. The left hemisphere is generally associated with logical thinking and language, while the right hemisphere is home to intuition, emotion, and artistic sense. The outer shell of the brain is made of gray matter, while the inner substance is white matter.
“The functional asymmetry of the cerebral hemisphere and its dominance in achieving neurophysiological performance is well known. Thus, the left hemisphere is dominant for language, while the right hemisphere has a specialization for higher visual-spatial, bodily and extracorporeal functions, human face recognition, intervenes in the modulation of voice, gestures and the pantomime The right hemisphere appears as a sensitive-emotional resonator, emotionally linked to artistic creativity, sensitive to visual, pictorial or musical patterns, being dominant in synthetic geometric and spatial functions. , rational, dominant in thinking, on abstract, conceptual functions, based on mathematical language, excelling in analytical processes. both cerebral hemispheres are integrated into harmonious brain activity, their neuropsychological functions being complementary “, explains. Simona Novac , primary care neurologist.
Are there differences between women’s and men’s brains?
“This question has aroused the interest of several groups of researchers and there have been several studies, some of them using state-of-the-art medical equipment, the results of which have proved to be contradictory. Usually, a man is bigger than a woman, and his brain is proportional to his body size. But the level of intelligence is not proportional to the size of the brain. Differences induced by hormone influences in brain structure and function have also been discussed, but scientists have concluded that although hormones play a role in each person’s personality, the brain is the result of a complex evolutionary process in which environment and education play a role. important (although there are psychologists who do not agree with the influence of the environment and believe that the differences between the brain are structured from birth) “, says Dr. Simona Novac, a primary neurologist.
