Mayo Clinic researchers have found a novel way to monitor real-time chemical changes in the brains of patients undergoing deep brain stimulation (DBS). The groundbreaking insight will help physicians more effectively use DBS to treat brain disorders such as Parkinson’s disease, depression, and Tourette syndrome. Included in this report is a video summary of the […]

Most cases of autism are not caused by a single genetic mutation. However, several disorders with autism-like symptoms, including the rare Fragile X syndrome, can be traced to a specific mutation. Several years ago, MIT neuroscientist Mark Bear discovered that this mutation leads to overproduction of proteins found in brain synapses — the connections between […]
Impulsive individuals tend to display aggressive behavior and have challenges ranging from drug and alcohol abuse, to problem gambling and difficult relationships. They are less able to adapt to different social situations. Impulsivity is also a common feature of psychiatric disorders. New research in Biological Psychiatry shows that people may react this way, in part, […]
Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons – a dance of chemical messages so delicate that missteps often lead to neurological dysfunction.
We are one step closer to deciphering why some stressed people indulge in chocolate, mashed potatoes, ice cream, and other high-calorie, high-fat comfort foods. UT Southwestern Medical Center-led findings, in a mouse study, suggest that ghrelin – the so-called “hunger hormone” – is involved in triggering this reaction to high stress situations. The results will […]
New research on the genomics of autism confirms that the genetic roots of the disorder are highly complicated, but that common biological themes underlie this complexity. In the current study, researchers have implicated several new candidate genes and genomic variants as contributors to autism, and conclude that many more remain to be discovered. While the […]
The laboratory of Huda Zoghbi, where the discovery that mutations in the gene MECP2 cause the severe childhood neurological disorder Rett Syndrome was made, has taken yet another step toward unraveling the complex epigenetic functions of this gene, implicated also in cases of autism, bipolar disease and childhood onset schizophrenia. The November 11 issue of […]
UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug. The findings were published in the journal Neuropsychopharmacology.
