Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Depression imaging test cited as real deal

Tired of hearing neuroscience, and brain imaging in particular, dismissed as trendy and overblown?

In this Sunday’s review section of the New York Times, Nobel Prize winner Eric Kandel cited research by Emory psychiatrist Helen Mayberg and colleagues (published in JAMA Psychiatry) as a good example of research with potential for substantive impact for the treatment of mental illness:

 In a recent study of people with depression, Professor Mayberg gave each person one of two types of treatment: cognitive behavioral therapy, a form of psychotherapy that trains people to view their feelings in more positive terms, or an antidepressant medication. She http://www.raybani.com/ found that people who started with below-average baseline activity in the right anterior insula responded well to cognitive behavioral therapy, but not to the antidepressant. People with above-average activity responded to the antidepressant, but not to cognitive behavioral therapy. Thus, Professor Mayberg found that she could predict a depressed person’s response to specific treatments from the baseline activity in the right anterior insula.

These results show us four very important things about the biology of mental disorders. First, the neural circuits disturbed by psychiatric disorders are likely to be very complex. Second, we can identify specific, measurable markers of a mental disorder, and those biomarkers can predict the outcome of two different treatments: psychotherapy and medication. Third, psychotherapy is a biological treatment, a brain therapy. It produces lasting, detectable physical changes in our brain, much as learning does. And fourth, the effects of psychotherapy can be studied empirically…

National Institutes of Mental Health director Thomas Insel also has commented on the technique’s clinical potential.

“For the treatment of mental disorders, brain imaging Ray Ban outlet remains primarily a research tool, yet these results demonstrate how it may be on the cusp of aiding in clinical decision-making,” Insel said in a NIMH press release earlier this summer.

In addition, author David Dobbs and blogger Neurocritic both delve into the details of Mayberg’s work.
