Male vs Female Brains

Older Men + Younger Women = Long Life

But now three scientists -- all males, by the way -- have taken a fresh look at the issue and produced a lot of data suggesting that men are part of the equation, too. Their study, "Why Men Matter: Mating Patterns Drive Evolution of Human Lifespan," was published in a recent edition of PLoS, an online public access journal. The study was conceived by Shripad Tuljapurkar, an internationally known expert on population at Stanford University.

Genes could explain memory differences between men and women - from the Telegraph, by Richard Gray, 2008/07/20

Scientists believe they have now uncovered the reason for this difference between the sexes – they make the memories in different ways.

Researchers at the Institute of Psychiatry, King's College London, have found that males use different genes from females when making the new connections in the brain that are needed to create long-term memories. They believe this might explain why men are far better at remembering "tactical" memories, such as travel directions and trivia, while women form more "emotional" memories such as birthdays, wedding anniversaries and details about the world around them.

Professor Peter Giese, who led the Medical Research Council- funded research , said they had identified two genes that seemed to be important for learning and making memories in males but not females.

He said: "It is unexpected that there should be such a difference within a species, but then we have to remember that males and females are far from identical at the genetic level as males have an X and Y chromosome while females have two X chromosomes.

One study at Harvard Medical School found that parts of the frontal lobe, which houses the decision-making and problem-solving functions, are larger in women compared to men. The limbic cortex, which regulates emotions, is also larger in women.

The Parietal cortex, which is involved in space perception and balance, is bigger in men. Professor Carey Cooper, a psychologist who specialises in sex differences at Lancaster University, said: "It is probably a combination of the genetics and hard wiring of the brain together with the social imprinting of gender that has led to the behavioural differences we now see between men and women."

Maybe this explains why my memory has fallen apart as I've grown more indifferent to more things.

He said: "It is unexpected that there should be such a difference within a species"

It sounds like he's lying there, since huge differences are common within a species. For example, compare how different a Queen ant is (a huge egg machine) from the tiny and sterile worker ants, and the massively armoured soldier ants, of the same species. Any biologist knows this.

I think he's trying to make is sound like he's sorry to be revealing a truth, but that he chanced upon it accidentally, and it's not his fault! The implication is that if he knew such a truth might be discovered, he wouldn't have enquired after it in the first place!

Well Kevin, he's a neuro-biologist after all, well known for their brilliant tunnel visions and the blocking out of any other discipline apart from their own. :)
