Smart people exhibit unique brain networking

Brain Networking

Scientists have explored the depth of human brains and derived a conclusion which states that Homo sapiens with an intelligent mind has a dense channel of brain networking which helps them carry and analyze information. The study published in Scientific Reports states that the intelligence exhibited by smart humans is directly related to the connections amidst the brain modules. A team led by Ulrike Basten who is a cognitive scientist at the Goethe University Frankfurt conducted a study on 309 individuals from various sections of society. The subjects were given an intelligence test while brains scans were being conducted on the individuals. This particular study provided a base for comparison of brain functioning in different people.

Modules are a concept which divides the brain functions into two parts. Some modules are associated with decision-making process like being able to catalog your thoughts in a particular pattern. The second types of modules assist with primary aspects such as having the ability to grab minute details from the surrounding environment. Both these modules are well connected to each other which lead to an enhanced brain functioning in Brainy individuals.

Basten explains, “The previous research used an outdated model of the brain which has now been eliminated, and a newer version of the same is being studied. It is a big step towards the understanding of brain operations.” Basten further explained that these so-called modules exhibit a social networking pattern. This means not all connections established can be strong. The right type of interaction between the significant modules is what separates the intelligent folks from the average ones.

This previous results from the same team published in the year 2015 acted as a base for the new research. The former study focused on the analysis of selective brains sections that activated differently for the leading performers of the general intelligence test. Brain regions such as the prefrontal cortex activate selectively permitting a different level of intelligence among different individuals.

The team concluded that in individuals with more intelligent brains, there was a vast networking system in the anterior insula as well as the anterior cingulate cortex with the rest of the brain. This helped in better processing of task-related information. It has been seen that brains that show higher IQ have a modified set of brain junction which is located between temporal cortex and the parietal cortex. This junction is related to shielding the brains against unnecessary information and is less connected to the overall brain network. This helps the brain filter out the unwanted information and thus directs more energy towards the ones that are relevant, thus increasing the intelligence factor.

Basten concluded, “As of now, science has been unable to pinpoint intelligence from the functioning of the brain. The paper does not provide enough evidence to suggest that intelligence is a biological factor and not an adapted capability. There is no certain way of predicting if brain patterns are the cause for intelligence or tasks like reading, learning and observing form the specific brain pattern. The two could also be interrelated.” To conclude, it is far from evident that intelligence is a biological factor and not an adaptive one.
