Scientists in Germany believe they may have unlocked the mystery of why some people are smarter than others.
In an article published in the journal of Scientific Reports, researchers at Goethe University Frankfurt scanned the brains of more than 300 participants in order to delineate what helps form human intelligence.
Following the extensive study, they found that individuals who demonstrated higher functioning mental capabilities possessed a stronger wiring network that encompassed disparate regions of the brain.
Researchers found that a stronger brain network between disparate regions of the brain strongly indicated higher intelligence
'In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged,' the study published on November 22 explains.

The paper added: 'This is similar to a social network which consists of multiple sub-networks (e.g., families or circles of friends).'
'Within these sub-networks or modules, the members of one family are more strongly interconnected than they are with people from other families or circles of friends. Our brain is functionally organized in a very similar way.'
The researchers, who examined the brains of 199 females and 110 males, found that individuals with better wiring of the anterior insula and
