Science News » HIV Variants in Spinal Fluid May Hold Clues in Development of HIV-related Dementia

NIMH-funded researchers found two variants of HIV in the cerebrospinal fluid (CSF) of infected study participants that were genetically distinct from the viral variants found in the participants’ blood. The study, published October 6, 2011, in the journal PLoS Pathogens, suggests these CSF variants may help to inform research on the development and treatment of cognitive problems related to HIV infection.

The Hidden Potential of Autistic Kids

When I was in fifth grade, my brother Alex started correcting my homework. This would not have been weird, except that he was in kindergarten--and autistic . His disorder, characterized by repetitive behaviors and difficulty with social interactions and communication, made it hard for him to listen to his teachers. He was often kicked out of class for not being able to sit for more than a few seconds at a time. Even now, almost 15 years later, he can still barely scratch out his name. But he could look at my page of neatly written words or math problems and pick out which ones were wrong.

Therapy in the Air

Feeling tense? Paying attention to your breathing for a few minutes could soothe your nerves. Practicing such mindful breathing regularly may even lead to better mental health, according to two recent studies.

In an experiment reported in May in the International Journal of Psychophysiology , researchers at Toho University School of Medicine in Japan taught healthy subjects to breathe deeply into their abdomen. After subjects maintained attention on breathing this way for 20 minutes, they had fewer negative feelings, more of the mood-boosting neurotransmitter serotonin in their blood, and more oxygenated hemoglobin in the prefrontal cortex, an area associated with attention and high-level processing.

Director’s Update » NIMH Grantees Elected to Membership in National Academy of Sciences

On May 3, 2011, nine NIMH grantees were among the 72 new members elected to the National Academy of Sciences, a private, non-profit organization of scientists and engineers dedicated to advancing science and promoting its uses for the greater good. The Academy also acts as an official advisor to the federal government on issues related to science and technology.

Do MRIs Relieve Symptoms of Depression?

When a researcher asks a volunteer to slide head-first into the open eye of a magnetic resonance imaging (MRI) machine, the expectation is that the device's magnetic field will penetrate the skull to produce a faithful picture of the brain without changing its behavior. A new study suggests, however, that MRI machines do, in fact, manipulate brain activity--and they change the brain in a way that helps treat depression. In other words, MRIs may be unintentional antidepressants . [More]

During REM Sleep Stress Chemicals Shut Down And The Brain Processes Emotional Experiences

They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful edge off difficult memories...
