Personality linked to ‘differences in brain structure’
London: Attributes of our personality are based on the volume and thickness of several different parts of the brain, a latest study has indicated.
The study has been conducted on some 500 people, according to which the people who have thick and wrinkled outer layers of the brain have more neurotic tendencies.
The study also informed that open-minded people have more thinly outer brain layer.
The study done by UK scientists and was difficult to interpret and published in the journal Social Cognitive and Affective Neuroscience.
The 500 people filled in the questionnaires which carried the questions including neuroticism, extraversion, openness, agreeableness and conscientiousness.
Researcher Dr Luca Passamonti from Cambridge University said the research could help them understand more about mental health over time.
He added: “Linking how brain structure is related to basic personality traits is a crucial step to improving our understanding of the link between the brain morphology and particular mood, cognitive or behavioral disorders.
“We also need to have a better understanding of the relation between brain structure and function in healthy people to figure out what is different in people with neuropsychiatric disorders.”
Meanwhile, the scientists have mentioned that the results cannot be accepted as ‘final’ and more research is needed to reach the conclusion.
Michael Anderson, an associate professor of psychology at Franklin and Marshall College, said the study was difficult to interpret, although it was “carefully done, using well-controlled methods.”
He said: “Most regions of the brain are associated with multiple cognitive and behavioural functions, so it can be difficult to say with any confidence which functions are relevant to these particular associations.”
He added: “Brain function is less a matter of the number of nerve cells being used or the amount of brain tissue being used and more about how nerves connect to each other – which is not investigated in this study.”
