By Gina Rippon. Men are better at fixing stuff — but only one thing at a time. Women, in contrast, can multitask, and do empathy and intuition better, too. So say the stereotypes, anyway. It is a widespread idea that men and women are distinguished not only by their genitals and related sexual characteristics, but also by their brains. According to this way of thinking, the biological blueprint that determines fixed and inevitable differences in our reproductive apparatus also determines similarly fixed and inevitable differences in the structure of our brains and how they work.
Men's and women's brains found to be different sizes
The science behind the differences in male and female brains
A new study finally confirms that the sexes really do have different brains, and suggests these variations start in the womb. The conclusion is a controversial one, as many experts think social influences are more important to the distinctive ways that men and women think. But scientists at New York University Langone say they've narrowed down a biological root after they took brain scans of more than foetuses in the womb. That's what I would expect," she told The Times.
Male vs. female brains - just how big are the differences?
Back to Mental health. It is well established that males and females have different predispositions towards developing different mental health conditions. New research has pooled the results of studies examining the differences in brain size between men and women to see if structural differences are part of the explanation. It found that on average men had larger overall brain volumes than women.
Researchers have identified a group of genes that induces differences in the developing brains of male and female roundworms and triggers the initiation of puberty, a genetic pathway that may have the same function in controlling the timing of sexual maturation in humans. The study, led by Columbia University scientists, offers new evidence for direct genetic effects in sex-based differences in neural development and provides a foundation to attempt to understand how men's and women's brains are wired and how they work. The research was published Jan. Scientists have long known that puberty is accompanied by substantial changes in the brain characterized by the activation of neurons that produce hormonal signals. But what causes the brain to start releasing the hormones that switch on puberty remains elusive.
