A joint study conducted by researchers in Madrid and Los Angeles found that while women's brains are smaller, they are far more efficient compared to brains of men.
The study, published in the journal Intelligence, involved around 59 women and 45 men between 18 and 27 years of age.
The researchers found that while women's brains are eight percent smaller compared to men they required less number of neurons and energy to complete a task, which negates the size difference between the two genders.
"At this structural level, females might show greater efficiency requiring less neural material for achieving behavioural results on a par with males. There is a positive association with hippocampus shape and cognitive performance in males, whereas for females this association is negative", the researchers wrote in their report.
