Emory scientists have identified a function for a mysterious DNA modification in fruit flies' brain development, which may provide hints to its role in humans.
New research shows that military veterans who participated in a three week, intensive outpatient treatment program for PTSD saw rapid and clinically meaningful improvements, adding the growing body evidence that several hours of therapy over several consecutive days could be an important step in addressing the unmet mental health needs of tens of thousands of military veterans.
Individual differences in the connectivity between regions of the brain involved in fear and anxiety are heritable, according to a large study of hundreds of related monkeys published in JNeurosci. The research provides new insights into the risk and development of anxiety disorders.
An analysis of more than 1,000 people with and without psychiatric disorders has shown that nitrates--chemicals used to cure meats such as beef jerky, salami, hot dogs and other processed meat snacks--may contribute to mania, an abnormal mood state. Mania is characterized by hyperactivity, euphoria and insomnia.
Research in mice shows that a pharmacological strategy can alleviate multiple behavioral and cellular deficiencies in a mouse model of fragile X syndrome, the most common inherited form of intellectual disability.
Study finds that six brain regions shared more responsibility than thought for how the brain moves from raw perception to determining the categorical meaning of what's seen.
Johns Hopkins researchers have found that the cellular 'garbage disposal,' known to scientists as proteasomes, may not only be responsible for the removal of cellular waste, but actually work on some of the most important proteins to neuronal development.
The hippocampus may relay predictions about what we expect to see based on past experience to the visual cortex, suggests a human neuroimaging published in JNeurosci. The study is among the first to examine the interaction between these two aspects of cognition.
Maternal use of the antidepressant fluoxetine (Prozac) can alter the brain circuits in her offspring that control behaviors reminiscent of autism spectrum disorder, suggests a study in mice published in eNeuro. These results have no immediate bearing on the treatment of depression in pregnant women.
Generally, children who experience recurrent destructive conflicts between their parents are at a higher risk of developing mental health problems. However, a new longitudinal study published in Child Development finds that strong sibling bonds can offset the negative effects of parental strife.
