When all these investigations began, scientists were skeptical about the role of genes and of biological differences, because cultural learning is very powerful and influential among humans. Are girls more prone to play with dolls and cooperate among themselves than boys, because they are taught to be so by parents, teachers and social peers, or is it the reverse order?

It is no secret that boys and girls are different – very different. The differences between genders, however, extend beyond what the eye can see. Research reveals major distinguishers between male and female brains.

Scientists generally study four primary areas of difference in male and female brains: processing, chemistry, structure, and activity. The differences between male and female brains in these areas show up all over the world, but scientists also have discovered exceptions to every so-called gender rule. You may know some boys who are very sensitive, immensely talkative about feelings, and just generally do not seem to fit the “boy” way of doing things. As with all gender differences, no one-way of doing things is better or worse. The differences listed below are simply generalized differences in typical brain functioning, and it is important to remember that all differences have advantages and disadvantages.

Processing

Male brains utilize nearly seven times more gray matter for activity while female brains utilize nearly ten times more white matter . What does this mean?

Gray matter areas of the brain are localized. They are information- and action-processing centers in specific splotches in a specific area of the brain. This can translate to a kind of tunnel vision when they are doing something. Once they are deeply engaged in a task or game, they may not demonstrate much sensitivity to other people or their surroundings.

White matter is the networking grid that connects the brain’s gray matter and other processing centers with one another. This profound brain-processing difference is probably one reason you may have noticed that girls tend to more quickly transition between tasks than boys do. The gray-white matter difference may explain why, in adulthood, females are great multi-takers, while men excel in highly task-focused projects.

Chemistry

Male and female brains process the same neurochemicals but to different degrees and through gender-specific body-brain connections. Some dominant neurochemicals are serotonin , which, among other things, helps us sit still; testosterone , our sex and aggression chemical; estrogen , a female growth and reproductive chemical; and oxytocin , a bonding-relationship chemical.

In part, because of differences in processing these chemicals, males on average tend to be less inclined to sit still for as long as females and tend to be more physically impulsive and aggressive. Additionally, males process less of the bonding chemical oxytocin than females. Overall, a major takeaway of chemistry differences is to realize that our boys at times need different strategies for stress release than our girls.

Structural Differences

A number of structural elements in the human brain differ between males and females. “Structural” refers to actual parts of the brain and the way they are built, including their size and/or mass.
