Advances in hitherto uncharted parts of the brain have been successfully carried out by science, which has managed to complete the mapping of the brain from fetal life to the age of 100.
The achievement called Brainchart is the work of 200 scientists and Greeks of the diaspora, who managed to create the most complete map of the human brain. The new map reveals the different stages the human brain goes through during life.
The creation of Brainchart was based on the combination of approximately 124,000 MRI scans of the brain from 101,457 people of various ages who came from all 6 continents and according to scientists it is expected to be an important weapon for understanding diseases especially neurological and psychiatric.
BrainChart confirms or identifies key developmental milestones of the human brain for the first time.
Some of his most interesting conclusions are:
– Brain cell gray matter volume, which is associated with intelligence, increases rapidly from about mid-pregnancy, peaks just before age 6, and then gradually begins to decline.
– The volume of white matter, which affects the learning process, also increases rapidly in the fetus from mid-pregnancy and peaks around the age of 29. White matter decline begins to accelerate after age 50.
– In adolescence, around the age of 14.5 years, the volume of gray matter in the subcortex, which controls bodily functions and basic behavior, peaks.
– Our brain has reached 80% of its final volume by the age of three. In fact, the important period of development, when rapid changes occur, is actually before birth.
– ¨As with other organs or features of the body, the brain is an organ that shows variety in healthy people. This does not mean that a small brain is associated with some pathological problem. The brains of people with disorders (dementia, schizophrenia, autism, etc.) show important differences, but also similarities.
Finally, as the new “map” also shows, while the brain shrinks naturally with age, this happens faster in the case of the person suffering from Alzheimer’s disease.
