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.
