When depression drives you to drink

When you drink, do you get depressed? Or is it the reverse: when you’re depressed, do you drink? An eight-year study of close to 1,300 teenagers by Canadian, American and German researchers appears to indicate the latter, and points to a solution: self-awareness. If people learn to recognize when they’re in a funk and deal with it, they’re less likely […]

Why nerve cells in the brain process information differently

The dentate gyrus is the “input point” for the hippocampus part of the brain. It transmits information from the short term memory to the long term. It consists of granule cells, which are especially dense in this area of the brain, and interneurons, which are linked up in the central or peripheral nervous system between several nerve cells and have […]

Controlling attention with brain waves

Having trouble paying attention? MIT neuroscientists may have a solution for you: Turn down your alpha brain waves. In a new study, the researchers found that people can enhance their attention by controlling their own alpha brain waves based on neurofeedback they receive as they perform a particular task. The study found that when subjects learned to suppress alpha waves […]

Online therapy helped cardiovascular disease patients with depression

Researchers at Linköping University have developed a treatment for depression among people with cardiovascular disease. The results, recently published in JMIR Mental Health, show that cardiovascular disease patients who underwent internet-based therapy for their depression became less depressed and gained a better quality of life. It is common that cardiovascular disease (CVD) patients suffer from depression. This can lead to […]

Concussion alters how information is transmitted within the brain

Damage from concussion alters the way information is transmitted between the two halves of the brain, according to a new study presented today at the annual meeting of the Radiological Society of North America (RSNA). Research has shown that the corpus callosum, a bundle of nerve fibers that carries signals between the brain’s left and right hemispheres, is vulnerable to […]

Bushmeat may breed deadly bacteria

People who eat wildebeests, wart hogs and other wild African animals may be at risk for contracting potentially life-threatening diseases, according to an international team of researchers. The team analyzed samples of bushmeat—meat derived from wildlife—in the Western Serengeti in Tanzania and identified several groups of bacteria, many of which contain the species that cause diseases such as anthrax, brucellosis […]

Unexpected viral behavior linked to type 1 diabetes in high-risk children

New results from The Environmental Determinants of Diabetes in the Young (TEDDY) study show an association between prolonged enterovirus infection and the development of autoimmunity to the insulin-producing pancreatic beta-cells that precedes type 1 diabetes (T1D). Notably, researchers also found that early adenovirus C infection seemed to confer protection from autoimmunity. The full findings were published Dec. 2 in Nature […]

Feeling loved in everyday life linked with improved well-being

Poets and songwriters may tend to focus their artistry on passion and romance, but it may be those unsung, brief feelings of love throughout the day that are connected with psychological well-being, according to a team of researchers led by two Penn State Institute for Computational and Data Sciences (ICDS) researchers. They added that the findings could one day lead […]
