Fighting like a girl or fighting like a boy is hardwired into fruit fly neurons, according to a study in the November 19 Nature Neuroscience advance online publication by a research team from Harvard Medical School and the Institute of Molecular Pathology in Vienna. The results confirm that a gene known as “fruitless” is a key factor underlying sexual differences in behavior.
The Baltimore Sun has started a new health story on situation in Iraq. In its first of a three-part series, titled Dangerous remedy, it highlighted that military doctors in Iraq say that Factor VII saves wounded soldiers, but other doctors and medical research suggest that it can cause fatal clots.
Yale School of Medicine has received a $6.6 million grant to study why the olfactory function declines as people age?research that could have implications for Alzheimer?s, Parkinson?s, and other neurodegenerative diseases.
Researchers at the University of Minnesota’s Institute for Human Genetics have shown for the first time that the severity of an adult neurodegenerative disease is tied to how well the brain developed shortly after birth.
Specific language impairment (SLI) is a condition in which a child’s language development is deficient despite showing normal development in all other areas. New research, published in Current Directions in Psychological Science, attempts to identify the cause behind this affliction.
Research from the University of Michigan Health System suggests that hormone therapy might help women retain certain memory functions. In a study in the new issue of the Journal of Clinical Endocrinology & Metabolism, they report that a group of postmenopausal women showed more brain activity during a visual memory test than did women who were not taking the hormone therapy.
Research has shown that most smoking in the US occurs among people who have psychiatric conditions, such as alcohol or drug abuse, major depression, anxiety and ADHD. Columbia University Medical Center researchers are recruiting smokers who have been diagnosed with ADHD to be part of a study that will help them quit smoking.
Brain and behavior relationships may have changed in a profound way as larger, more complex insect societies evolved from smaller, simpler ones, according to a new study.
A device first implanted in the United States at the University of Rochester Medical Center as part of a clinical trial is showing a significant reduction in blood pressure in patients who suffer from severe hypertension and cannot control their condition with medications or lifestyle changes.
During sleep, freshly minted memories move from the hippocampus, part of the “old” brain, to the neocortex, or “new” brain, for long-term storage. This has been the reigning theory for decades. Brown University research provides the strongest proof yet of this interaction between the old and new brains — and offers surprising evidence that challenges critical details of this theory of learning and memory. Results appear in Nature Neuroscience.
