First validated canine behavioral genetics findings of nine fear, aggression traits in dogs Anxiety disorders are the most common type of mental illness in the United States. And while much is understood about the biochemistry of anxiety, little is known about the genetic variation associated with it. A new study reports that genetic predisposition to aggression toward an owner or a familiar dog is distinct from that for fear and aggression directed at unfamiliar humans and dogs.
How incivility spreads in the workplace Condescending comments, put-downs and sarcasm have become commonplace in the politically charged workplace, and a new study co-authored by a Michigan State University business scholar shows how this incivility may be spreading. Reporting in the Journal of Applied Psychology, Russell Johnson and colleagues found that experiencing such rude behavior reduces employees’ self-control and leads them [...]
Study reveals association between physical function and Alzheimer’s disease A new study, based on data from the Framingham Heart Study (FHS) suggests a simple test of physical functioning may be able to help physicians identify individuals who are at a higher risk for developing Alzheimer’s disease and stroke. These findings, which appear in the Journal of Alzheimer’s Disease, provide hope that there are easy-to-test [...]
Brain stimulation technique shown effective in phantom limb pain As many as 25,000 people a year worldwide lose limbs from land mine blasts, and a new study shows that transcranial magnetic stimulation (rTMS) administered to the scalp can stimulate the brain and provide significant reductions in phantom limb pain.
Total number of neurons — not enlarged prefrontal region — hallmark of human brain A new scientific study puts the final nail in the coffin of a long-standing theory to explain human’s remarkable cognitive abilities: that human evolution involved the selective expansion of the brain’s prefrontal cortex. It does so by determining that the prefrontal region of the brain which orchestrates abstract thinking, complex planning and decision making contains [...]
Children can benefit when adoptive and biological parents share adoption stories For most of the 20th century, adoptions were largely “closed,” meaning birth parents placed their child with an adoption agency and had no further contact unless the child sought them out later in life. However, statistics show that a shift occurred in the 1990s when adoption practitioners started to recognize the benefits of “open” adoptions, [...]
New PET scan tracer allows first imaging of the epigenetics of the human brain A novel PET radiotracer developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) is able for the first time to reveal epigenetic activity – the process that determines whether or not genes are expressed – within the human brain. In their report published in Science Translational Medicine, a team of MGH/Martinos [...]
Molecule in brain may drive cocaine addiction, scientists show Increased levels of a molecule in the brain, called hypocretin, may contribute to cocaine addiction, a new study suggests. The research shows that blocking hypocretin may reduce compulsive drug-seeking behavior in rat models of cocaine addiction.
Scientists show hypocretin molecule in brain may drive cocaine addiction A new study from scientists at The Scripps Research Institute (TSRI), funded by the National Institutes of Health’s (NIH) National Institute on Drug Abuse (NIDA) and National Institute on Alcohol Abuse and Alcoholism (NIAAA), suggests that increased levels of a molecule in the brain, called hypocretin, may contribute to cocaine addiction. The research, published recently [...]
New study evaluates link between young women’s beliefs on alcohol use and sex It may come as little surprise that alcohol use is widespread among young adults. In the U.S., 70 percent of adults aged 18 to 24 drink alcohol, with 40 percent of women imbibing over the recommended daily limit of 3 drinks per day. Add that to preconceived notions that alcohol-related behavior results in sexual risk-taking, [...]
Violent games not linked to antisocial attitudes among children, study finds Whether violent video games influence the behavior of youth has been a debate that has split the academic community for years. Scholars and clinicians remain divided in opinion about whether violent games are harmful. In 2011, the US Supreme Court, in a decision examining the constitutionality of regulating the sale of violent games to minors, [...]
Plenty of light during daytime reduces the effect of blue light screens on night sleep The use of smartphones and tablet computers during evening hours has previously been associated with sleep disturbances in humans. A new study from Uppsala University now shows that daytime light exposure may be a promising means to combat sleep disturbances associated with evening use of electronic devices. The findings are published in the scientific journal [...]

Total number of neurons -- not enlarged prefrontal region -- hallmark of human brain New study has determined that the total number of neurons, not an enlarged prefrontal region, differentiates the human brain from those of other primates.
Why It’s Important to Be Positive About Mental Illness... I love hope-filled stories of recovery from mental illness. Living with bipolar disorder has led to many instances of triumph over my circumstances and I often write about them. As anyone who lives with or knows someone with mental illness is aware, it’s a horrible … ...
Gene signature in healthy brains pinpoints the origins of Alzheimer's disease Researchers have discovered a gene signature in healthy brains that echoes the pattern in which Alzheimer's disease spreads through the brain much later in life. The findings could help uncover the molecular origins of this devastating disease, and may be used to develop preventative treatments for at-risk individuals to be taken well before symptoms appear.
