Women may have smaller brains than men, but they are more efficient at
completing a task, a new study has claimed. It has been a mystery for
scientists why women show no difference in intelligence , although their
brains are 8% smaller than men's .
Neuroscientists at the University of California, Los Angeles , and
universities in Madrid , Spain found that women's brains are more
efficient , needing fewer neurons and less energy to complete a task.
The study conducted a number of psychological tests on 59 women and 45
men, aged 18-27 . They found that in women the hippocampus, which plays a
central role in memory, intelligence and emotion, consumes less energy
and uses fewer brain cells on a given task than in men, The Sunday Times
reported.
The study found that women outperformed men in inductive reasoning and
some numerical skills. They were also better at keeping track of a
changing situation, while men did better on spatial intelligence .
"There is a positive association with hippocampus shape and cognitive
performance in males, whereas for females this association is negative,"
said the study.
