redOrbit Staff & Wire Reports - Your Universe Online Using deep brain stimulation (DBS) in a specific area of the brain appears to reduce caloric intake and lead to weight loss in obese mice prone to binge eating, according to new research published in the Journal of Neuroscience, the official Journal of the Society of Neuroscience. Senior author Tracy L. Bale, an associate professor of neuroscience at the University Pennsylvania's School of Veterinary Medicine's Department of...

Implications for early diagnosis and new treatment strategies An excess of the brain neurotransmitter glutamate may cause a transition to psychosis in people who are at risk for schizophrenia, reports a study from investigators at Columbia University Medical Center (CUMC) published in the current issue of Neuron. The findings suggest 1) a potential diagnostic tool for identifying those at risk for schizophrenia and 2) a possible glutamate-limiting treatment strategy to prevent or slow...

The gene variants weaken the same receptors that some hallucinogenic drugs block New genetic factors predisposing to schizophrenia have been uncovered in five families with several affected relatives. The psychiatric disorder can disrupt thinking, feeling, and acting, and blur the border between reality and imagination. Dr. Debby W. Tsuang, professor of psychiatry and behavioral sciences, and Dr. Marshall S. Horwitz, professor of pathology, both at the University of Washington in...

How Drosophila recovers the neurotransmitter histamine In the fruit fly Drosophila, the functions of the three enzymes Tan, Ebony and Black are closely intertwined - among other things they are involved in neurotransmitter recycling for the visual process. RUB researchers from the Department of Biochemistry showed for the first time that flies cannot see without this recycling. Their analysis of the enzyme Black also raises new questions as to its function. Anna Ziegler, Florian...

Since the 1960s, psychiatrists have been hunting for substances made by the body that might accumulate in abnormally high levels to produce the symptoms associated with schizophrenia. In particular, there was a search for chemicals that might be related to the hallucinogens phencyclidine (PCP) or lysergic acid diethylamide (LSD), which could explain the emergence of psychotic symptoms in schizophrenia. This "auto-intoxication" hypothesis led investigators on a wild goose chase where...

In a new study in Neuron, scientists identified specific key steps in the chain of events that causes stress-related drug relapse. They identified the exact region of the brain where the events take place in rat models and showed that by blocking a step, they could prevent stress-related relapse. All too often, stress turns addiction recovery into relapse, but years of basic brain research have provided scientists with insight that might allow them develop a medicine to help. A new study...

Nitric Oxide Keeps Stroke-damaged Brain From Repairing Itself
2013-02-04 15:13:42

Sanford-Burnham Medical Research Institute In stroke and other neurological disorders, nitric oxide damages neurons and blocks the brain's ability to repair itself Nitric oxide, a gaseous molecule produced in the brain, can damage neurons. When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer's. Researchers at Sanford-Burnham Medical Research Institute recently discovered that nitric oxide...
