The main myths about the human brain that many believe in vain

The article debunks popular myths about the human brain, including the use of only 10% of its capabilities, the connection between brain size and intelligence, the impossibility of nerve cell recovery, the gray color of the brain, and the inevitable decline of intelligence with age.

The article debunks five common myths about the human brain. The first myth — about using only 10% of the brain — is refuted by neuroimaging data (MRI, PET), showing activity in various areas even during sleep. The second myth about the connection between brain size and intelligence: Neanderthals had larger brains, but this did not provide cognitive advantages; intelligence depends on neural connections and the development of the frontal lobes. The third myth about the non-recovery of nerve cells is refuted by the discovery of neurogenesis in the hippocampus throughout life. The fourth myth about the gray color of the brain: in a living person, it is pinkish-red due to blood vessels, becoming gray after death. The fifth myth about the inevitable decline of intelligence with age: brain plasticity allows the development of new neural connections through mental activity, a healthy diet, and physical exercise.
