Detailed explanation-1: -They found that different brain regions use different strategies to interact with each other. This combination of complementary information between different sources is known as ‘synergy’ and may explain why the human brain is smarter than our primate ancestors.
Detailed explanation-2: -We have more neurons in our brain’s cerebral cortex (its outermost layer) than other mammals do. The insulation around nerves in the human brain is also thicker than that of other species, enabling the nerves to conduct signals more rapidly.
Detailed explanation-3: -According to the “cultural brain hypothesis, ” humans evolved large brains and great intelligence in order to keep up with our complex social groups. We’ve always been a social species, and we may have developed our intelligence in part to maintain those relationships and function successfully in these environments.
Detailed explanation-4: -While there has been much speculation regarding brain size and intelligence, a new paper published in the journal Proceedings of the National Academy of Sciences confirms that species with brains that are large relative to their bodies are more intelligent.
