People love to speculate about differences between the sexes, and neuroscience has brought a new technology to this pastime. Brain imaging studies are published at a great rate, and some report sex differences in brain structure or patterns of neural activity. But we should be skeptical about reports of brain differences between the sexes, writes psychological scientist Cordelia Fine in Current Directions in Psychological Science, a journal of the Association for Psychological Science. The...

A study of 145 preschool children reports, for the first time, that when the concentrations of two common phthalates in mothers' prenatal urine are elevated their sons are less likely to play with male-typical toys and games, such as trucks and play fighting. The University of Rochester Medical Center-led study is published in the International Journal of Andrology. Because testosterone produces the masculine brain, researchers are concerned that fetal exposure to anti-androgens such as...

Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop. This is shown by a new study by Uppsala University researchers Elena Jazin and Björn Reinius, which has been published in the latest issue of the journal Molecular Psychiatry. Professor Elena Jazin and doctoral student Björn Reinius at the Department of Physiology and Developmental Biology...

It's often said that overly macho males suffer from "too much testosterone." But a new study in mice reveals how estrogen might share in that blame. The report in the October 2nd issue of Cell, a Cell Press publication, reveals how early estrogen exposure "masculinizes" the brain circuitry, predisposing boys to be boys as it were. That early event is specifically critical in producing male mice that will pick fights with other males and that dutifully mark their territories with urine. "It's...

Congress is expected to take up legislation this summer aimed at improving the nation's healthcare system. Whatever the shape of the final bill, it will have at least some impact on one of the three leading causes of death in the U.S.: stroke.Stroke typically occurs when arteries become blocked, preventing blood from flowing to the brain. When the brain is deprived of blood and oxygen, brain cells die and long-term brain damage results. For this reason, a stroke is also known as a brain...

A gene essential to growth and development of most organ systems is also vital to female, but not male, embryonic sexual development, U.S. researchers say. Researchers at the University of Illinois and the University of Texas say the findings lend support to a controversial hypothesis about mammalian sexual development. In terms of their sexual organs, all embryos look alike, study leader Humphrey Yao, of the University of Illinois said. "They have a common primordium, the foundation...

Could a gene linked with testosterone impact the occurrence of male transsexuals? Australian scientists say yes, according to new research. Research Vincent Harley said, "There is a social stigma that transsexualism is simply a lifestyle choice, however our findings support a biological basis of how gender identity develops."DNA analysis from 112 male-to-female transsexual volunteers showed they were more likely to have a longer version of the androgen receptor gene; a genetic difference that...
