NOTE that the (2 male) authors of the study are careful to emphasize that the great differences in M==F brain systems/processing "are capable of producing equivalent intellectual performance", as measured on intelligence tests. So...the next step is to bring it to the Real World, comparing, for example, woman managers/teachers/students, w/male managers/teachers/students.

As a left-handed male w/mixed cerebral dominance, I say "long live the difference!!" It seems the female White Areas are especially in-sync w/Gardner's latest Multiple Intelligence--Ecological.

Intelligence in men and women is a gray and white matter

Men and women use different brain areas to achieve similar IQ results, UCI study finds

Irvine, Calif. , January 20, 2005

While there are essentially no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence.

The study shows women having more white matter and men more gray matter related to intellectual skill, revealing that no single neuroanatomical structure determines general intelligence and that different types of brain designs are capable of producing equivalent intellectual performance.

�These findings suggest that human evolution has created two different types of brains designed for equally intelligent behavior,� said Richard Haier, professor of psychology in the Department of Pediatrics and longtime human intelligence researcher, who led the study with colleagues at UCI and the University of New Mexico. �In addition, by pinpointing these gender-based intelligence areas, the study has the potential to aid research on dementia and other cognitive-impairment diseases in the brain.�

Study results appear on the online version of NeuroImage.

In general, men have approximately 6.5 times the amount of gray matter related to general intelligence than women, and women have nearly 10 times the amount of white matter related to intelligence than men. Gray matter represents information processing centers in the brain, and white matter represents the networking of � or connections between � these processing centers.

This, according to Rex Jung, a UNM neuropsychologist and co-author of the study, may help to explain why men tend to excel in tasks requiring more local processing (like mathematics), while women tend to excel at integrating and assimilating information from distributed gray-matter regions in the brain, such as required for language facility. These two very different neurological pathways and activity centers, however, result in equivalent overall performance on broad measures of cognitive ability, such as those found on intelligence tests.

The study also identified regional differences with intelligence. For example, 84 percent of gray-matter regions and 86 percent of white-matter regions involved with intellectual performance in women were found in the brain�s frontal lobes, compared to 45 percent and zero percent for males, respectively. The gray matter driving male intellectual performance is distributed throughout more of the brain.

According to the researchers, this more centralized intelligence processing in women is consistent with clinical findings that frontal brain injuries can be more detrimental to cognitive performance in women than men. Studies such as these, Haier and Jung add, someday may help lead to earlier diagnoses of brain disorders in males and females, as well as more effective and precise treatment protocols to address damage to particular regions in the brain.

For this study, UCI and UNM combined their respective neuroimaging technology and subject pools to study brain morphology with magnetic resonance imaging. MRI scanning and cognitive testing involved subjects at UCI and UNM. Using a technique called voxel-based morphometry, Haier and his UCI colleagues converted these MRI pictures into structural brain �maps� that correlated brain tissue volume with IQ.

Dr. Michael T. Alkire and Kevin Head of UCI and Ronald A. Yeo of UNM participated in the study, which was supported in part by the National Institute of Child Health and Human Development.

The neuropsych prof. who lectured at my college also said that the idea of left = analitical and right = creative is also a fundamental farce, making the term "mixed cerebral dominance" kind of a cock up in the first place.

RE: "cerebral dominance"...if you have it, you can KNOW it. Words can be stored on both sides.

There's also eye dominance, which can be easily tested.

A Simple Test for Brain Dominance
Take a sheet of paper, roll it into a tube, sight through it at some distant object.

The eye you hold the tube to, and/or are most comfortable using to look through the tube, is your dominant eye.



Which ear do you hold your phone to most of the time?


I think you already know your handedness.


Climb up to stand on the seat of a (sturdy) chair. Which foot did you go up with first? Which foot do you start up a flight of stairs with? Which do you usually use to step up on a curb? That is your dominant leg and foot.

Step down from that chair. The foot you lead with stepping down is your sub-dominant foot; the other is your dominant foot.

Really simple stuff, but it gives you a pretty good read-out on which functions are dominant for you, and indeed whether you are largely straight-dominant or mixed-dominant. The late Ned Herrmann, at Lake Lure, North Carolina, had a much more sophisticated system for sorting out brain preferences, but the above will do for most purposes.

And if you are one of the people reading this who has undergone "mid-life crisis," chances are that a year or so before that crisis began, you suffered some sort of injury or problem to your dominant foot or ankle or knee or leg. (!!!)

A TECHNIQUE for CEREBRAL INTEGRATION

Another Flax-Effect, discovered after years of neurolinguistic research - the NOSTRIL approach to creating "integration", mixed cerebral dominance.
When we cover one nostril and deeply inhale for sixty seconds exclusively through only "one"of our two nostrils - we cause a change in the functioning of our two-brains.

If we are preparing for an exam or giving a presentation, or an interview, we want to gain an "integrated" state-of-mind, with no single dominance by either the left or right brain.

Here's how we do it. Cover your left-nostril and inhale deeply through the exposed right nostril, thus activating your RIGHT-Brain. Our right-brain controls the left-half of our body - intuition, insight and imagination through spatial, nonverbal thinking.

After 60 seconds we switch, and cover your right-nostril, inhaling deeply through your left-nostril, feeding high-dose oxygen and lighting-up your LEFT-brain - controlling the right-side of your body. You now activate our language and long-term memory centers.

Almost there. Third step: inhale deeply for sixty-seconds through BOTH nostrils to cause integration and communication between left and right brains. It will last for a maximum of 2 hours, and during a long exam should be repeated hourly. That the Flax approach to cerebral integration, and it works to increase reading speed, comprehension and long-term memory. This is the speed reading approach to Verbal efficiency and "thinking".
