Spring arrived on March 20th and it was hard to ignore. It was a hot day in Central Park with fellow New Yorkers rushing out to sit in the sun, play ball, or ride their bikes. In my hometown people rushed to the Bluff just to sit in the sand and stare off into the water of Long Island Sound. There were some die hard jet skiers that took the opportunity to get their jet skies into the water (even though the water was an icy 40 degrees). People are craving to be outside; to shake More >
A study published in last week’s Science magazine shows how genomic science and neuroimaging can be combined to deliver insights into cognitive disorders. As well as providing an intriguing look into the neurobiology of psychosis, the study reflects a growing trend toward inter-disciplinary research in the neurosciences,
What did the study show?
Psychosis is a disordered cognitive state that can include disorganized thoughts, delusions, or hallucinations. It is a common symptom of schizophrenia and has been linked to a number of brain areas, including the the dorsolateral prefrontal cortex (DLPFC) and the hippocampus. Schizophrenia is also strongly associated with a number of genes, and More >
Duke University’s Rajendra Morey was in the news this week following a presentation at the World Psychiatric Association Congress in Italy. Dr Morey’s group recently published a paper equating symptoms of post posttraumatic stress disorder (PTSD) with “markedly different neural activity”. Dr. Morey raised the possibility of using brain scans to diagnose PTSD, thereby catapulting herself into the science pages of Forbes, Reuters et al. She joins a lengthy list of researchers that have whetted our appetite with tantalizing suggestions about the predictive power of neuroimaging. Sadly, the list of those who have followed through on this promise is not quite so More >
