This is a response to Vol 6 John 18 ("Closing the Gap")...
I recently came across an interesting article regarding the differences in male and female brains. Apparently new findings are emerging from the field of neuropsychology of sex differences which indicates that parts of the corpus callosum (fibers that connect the right and left hemispheres of the brain) are larger in women than in men.
This is a surprising finding because, overall, men's brains are larger than women's brains (presumably because men tend to be larger than women). Anyway, because the corpus callosum ties together so many parts of the brain, differences found here suggests that far more widespread disparities exist between men and women in the anatomical structure of the brain.
These findings, though still very preliminary, are potentially of great significance. They are already being linked to women's superiority on some tests of verbal intelligence. It is hoped that it can aid future understanding of why boys have more problems with dyslexia than girls and why women recover more more quickly and more often from certain kinds of brain damage (thereby guiding treatment).
However, the degree to which education and experience can override the differences attributed to brain structure remains unclear. Moreover, researchers are quick to point out that the brains of men and women are far more similar than they are different.
