People with generalized anxiety disorder, or GAD, have abnormalities in the way their brain unconsciously controls emotions. That’s the conclusion of a new Stanford University School of Medicine study, and the study authors say the findings could open up new avenues for treatments and change our understanding of how emotion is regulated in everyday life. […]
The current investigation utilized magnetoencephalography to map cortical hubs in tinnitus. Tinnitus is defined as an auditory perception in the absence of any physically identifiable source. Almost everyone will experience some form of auditory phantom perceptions such as tinnitus at least once in their lifetime; in most of the cases this sensation vanishes within seconds […]
When we put an idea on the back burner, it goes into a processing area of the brain called the default-mode network. This network enables us to hold the low-priority idea in abeyance until a time when we are not busy with something else. “The default-mode network appears to be the brain’s back burner for […]
In different, but similar study, researchers at Universitat Autònoma de Barcelona and the Vall d’Hebron University Hospital for the first time have discovered anomalies in the brain’s reward system related to the neural circuits of motivation and gratification. In children with Attention-Deficit Hyperactivity Disorder (ADHD), the degree of motivation when carrying out an activity is […]
What if a jury could decide a man’s guilt through mind reading? What if reading a defendant’s memory could betray their guilt? And what constitutes ‘intent’ to commit murder? These are just some of the issues debated and reviewed in the inaugural issue of WIREs Cognitive Science, the latest interdisciplinary project from Wiley-Blackwell, which for […]
Researchers at the University of Minnesota and Minneapolis VA Medical Center have identified a biological marker in the brains of those exhibiting post-traumatic stress disorder (PTSD). A group of 74 United States veterans were involved in the study, which for the first time objectively diagnoses PTSD using magnetoencephalography (MEG), a non-invasive measurement of magnetic fields […]
Estimates are that some 10 percent of people over the age of 65 will develop Alzheimer’s disease, the scourge that robs people of their memories and, ultimately, their lives. While researchers race to find both the cause and the cure, others are moving just as fast to find the earliest signs that will predict an […]
A brain-imaging study conducted at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory provides the first definitive evidence that patients suffering from attention deficit hyperactivity disorder (ADHD) have lower-than-normal levels of certain proteins essential for experiencing reward and motivation. “These deficits in the brain’s reward system may help explain clinical symptoms of ADHD, including […]
