Men and women are equally smart, but each sex uses different parts of the brain to solve problems or achieve goals, explained neuroscientist Daniel G. Amen in his new book, Unleash The Power Of The Female Brain.
Women are better at packing carefully for a family holiday because they have more brain cells in the pre-frontal cortex, the area which controls judgement, planning, and conscientiousness, he said.
Men can be more volatile and swift to anger in a crisis. It's may be because the part of their brain, the amygdala, which processes fear and anger, is much larger than a woman's, according to the book.
The human brain is made up of grey matter (brain cells) that does the thinking, and white matter (the communication cables between brain cells), which connects different bits of the brain.
Studies have now shown that grey and white matter are differently distributed in men and women, which has massive implications for the way they behave, G. Amen noted.
Because men have more grey matter in the bit of the brain that governs intelligence, they are inclined to tackle a task with single-minded focus, not taking into account the peripheral issues that a woman might consider to be important.
On the other hand women have more white matter in the part of the brain that governs intelligence, this is the reason why when women tackle a problem, they draw on many areas at the same time, he said.
Science have also proved that women have far more cells in the part of the brain that controls empathy, which explains why they cry more often in sad movies.
There is something unique about the structure and functioning of the female brain which gives women a distinct advantage when it comes to intuition.
Scans show that when women are thinking, they dip into the right side of the brain, which specialises in emotional issues. This makes women much better at picking up on cues, such as body language or tone of voice, that men may miss.
Scans confirm that women have larger areas in the brain dedicated to tracking gut feelings, which is why they're quicker at working out what others are thinking and reach conclusions based on hunches.
Women find it easier to keep strong negative emotions in check because the area of the brain, which deals with anger and aggression, tends to be larger in women than men, the author said.
Brain scans also showed that when a woman is feeling aggressive, she's much more likely to launch a verbal attack - using the highly active language part of her brain - than a physical one.
Moreover, women generally have lower levels of the brain chemical serotonin than men, and low levels are normally associated with over-activity in the brain's worry centres, the book stated.
