In a new study, researchers have found that human brain has different personality traits that can affect cognitive as well as anatomical factors. According to study authors, they have successfully identified interlink between brain structure and functions like intelligence and memory.
“A major focus of research in cognitive neuroscience is understanding how intelligence is shaped by individual differences in brain structure and function,” said study leader Aron K Barbey, a professor at University of Illinois.
Brain has been the biggest mystery among all the body parts as thousands of scientists have spent all of their life in determining a relation between specific areas of the brain and how they affect cognitive functioning like intelligence, memory and comprehensive skills.
First author Patrick Watson, from Beckman Institute for Advanced Science and Technology in US, explained that his team has examined the nerve fibre bundles, volume, blood flow, cortical thickness and white matter tracts for understanding how these physical elements affect the functioning of brain.
For the study, researchers used a technique maned independent component analysis that unleashes the power of statistics and then divided them into four unique traits. After analysing the data, study authors were able to answer for all the differences and functioning of the brain except for few like differences in cognitive abilities between people.
“We were able to identify cognitive-anatomical characteristics that predict general intelligence and account for individual differences in a specific brain network that is critical to intelligence, the fronto-parietal network,” Barbey said.
The study has given a deeper insight into how our brain functions and what affect traits. A larger study is needed to further solve the unanswered queries including why intelligence of people differs.
