NIBIB-funded researchers have used fast fMR Ito image rapidly fluctuating brain activity during human thought. fMRI measures changes in blood oxygenation, which were previously thought to be too slow to detect the subtle neuronal activity associated with higher order brain functions. The new discovery is a significant step towards realizing a central goal of neuroscience research: mapping the brain networks responsible for human cognitive functions such as perception, attention, and awareness.

Although both group and individual therapy can ease post-traumatic stress disorder (PTSD) symptoms in active-duty military service members, individual therapy relieved PTSD symptoms better and quicker, according to a study led by a Duke University School of Medicine researcher. The randomized clinical trial is the largest to date to examine an evidence-based treatment for active-duty military service members, with 268 participants from the U.S. Army’s Fort Hood in Killeen, Texas. Findings will be published Nov. 23 in JAMA Psychiatry.

Private speech is a good thing for a child’s cognitive development; however, it may be important that children monitor and repair errors in their speech, even when talking to themselves. Louis Manfra, assistant professor in the College of Human Environmental Sciences at the University of Missouri, found that children do, in fact, monitor their speech for errors, even without a listener. Manfra says parents and caregivers might encourage preschool-aged children to monitor their private speech by demonstrating such behavior in their own aloud private speech.

While schizophrenia is best known for episodes of psychosis – a break with reality during which an individual may experience delusions and hallucinations – it is also marked by chronic neurocognitive deficits, such as problems with memory and attention. A multi-site cognition study led by psychologists at Beth Israel Deaconess Medical Center (BIDMC) found that these neurocognitive symptoms are evident prior to the onset of psychosis in a high-risk stage of the disorder called the prodromal phase. The findings suggest that these impairments may serve as early warning signs of schizophrenia, as well as potential targets for intervention that could mitigate the onset of the psychotic disorder and significantly improve cognitive function.

Visual hallucinations ... everyone has heard of them, and many people have experienced the sensation of "seeing" something that isn't there. But studying the phenomenon of hallucinations is difficult: they are irregular, transitory, and highly personal--only the person experiencing the hallucination knows what he or she is seeing, and representations of what's being seen are limited to verbal descriptions or drawings.

We all know that the way someone sees the world, and the way it really is, are not always the same. This ability to recognize that someone’s beliefs may differ from reality has long been seen as unique to humans. But new research on chimpanzees, bonobos and orangutans suggests our primate relatives may also be able to tell when something is just in your head. The study was led by researchers of Duke University, Kyoto University, the University of St. Andrews and the Max Planck Institute for Evolutionary Anthropology.

And the greater the reward, the more often the rats’ brains replay it.
