Polyphenols can reduce inflammation in older people by altering the intestinal microbiota and inducing the production of indole 3-propionic acid.
Study sheds new light on the genetics underlying possible social differences between modern humans, our ancestors, and other primate species.
Study links acute stress as a result of childhood maltreatment to accelerated early maturation of the immune system.
A new study sheds light on the neurobiology of cravings for certain foods women experience while pregnant. According to researchers, during pregnancy, the brain undergoes alterations to functional connections in the reward systems, as well as taste and sensorimotor centers. Pregnant females become more sensitive to sweet foods and develop binge eating behaviors toward high-calorie foods. Pregnancy induces a full reorganization of the mesolimbic neural circuits via D2R dopaminergic neurons in the nucleus accumbens.
Researchers report it's easier to control cognitive activity via transcranial magnetic stimulation in people with the Val/Val genetic variant of BDNF.
It's a question most new parents ponder, can a newborn baby discriminate between speech sounds? Researchers found newborn babies encode voice pitch comparable to adults exposed to a new language for three years. However, there are some differences when it comes to distinguishing between spectral and temporal fine structures of certain sounds.
The largest genetic map of mental health disorders to date reveals there are three groups of highly genetically related disorders among eight psychiatric disorders. A gene related to nervous system development is a risk factor for all eight disorders studied. The RBFOX1 gene is implicated in seven of the eight disorders. ADHD and depression share 44% of genetic risk factors common in the general population. 109 pleiotropic loci affect more than one disorder. These pleiotropic loci are within genes that show heightened expression in the brain through the lifespan, beginning during the second trimester of pregnancy.
White matter connectivity between the auditory processing areas and brain areas associated with reward may explain why we like, or dislike music.
Researchers have identified 40 new genes they believe are related to aggressive behavior in both humans and mice. The findings deepen understanding of the genetic basis of aggressiveness.
