(ORDO NEWS) — The researchers found that the human and primate brains differ significantly in the level of neural connections between regions. This helps people to maintain clarity of thought for a long time.
The experiments went in two directions. One involved three-dimensional computer models of the brains of fossil primates.
These are hundreds of samples of the brain of ancient monkeys, as well as primitive people and related species.
The second technique was to study modern apes and humans. Changes were observed at different stages of growth.
The mammalian brain is divided into four lobes, each evolution endowed with special functions. The area of responsibility of the frontal lobe is abstract thinking; memory controls the temporal.
The occipital region is responsible for vision; the parietal region is designed to respond to sensory inputs and integrate them.
It turned out that in monkeys, the integration of different areas remains approximately at the level of a child, until the time when he enters adolescence. Then there is the “growing up” of the brain.
In humans, there is a high, compared with other primates, level of interconnections between parts of the brain.
First of all, scientists note the interaction of the frontal and parietal lobes. But among Neanderthals, experts add, the integration between them was about the same.
