Marijuana dependence alters the brain's response to drug paraphernalia

Marijuana dependence alters the brain's response to drug paraphernalia

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users.

The study, published July 1 in Drug and Alcohol Dependence, demonstrated that different areas of the brain activated when dependent and non-dependent users were exposed to drug-related cues.

Mutation stops worms from getting drunk

Mutation stops worms from getting drunk

Neuroscientists at The University of Texas at Austin have generated mutant worms that do not get intoxicated by alcohol, a result that could lead to new drugs to treat the symptoms of people going through alcohol withdrawal.

The scientists accomplished this feat by inserting a modified human alcohol target into the worms, as reported this week in The Journal of Neuroscience.

New knowledge about the brain's effective bouncer

Research from the University of Copenhagen is shedding new light on the brain's complicated barrier tissue. The blood-brain barrier is an effective barrier which protects the brain, but which at the same time makes it difficult to treat diseases such as Alzheimer's. In an in vitro blood-brain barrier, researchers can recreate the brain's transport processes for the benefit of the development of new pharmaceuticals for the brain. The new research findings are published in the AAPS Journal.

Transplantation of new brain cells reverses memory loss in Alzheimer's disease model

SAN FRANCISCO, CA—A new study from the Gladstone Institutes has revealed a way to alleviate the learning and memory deficits caused by apoE4, the most important genetic risk factor for Alzheimer's disease, improving cognition to normal levels in aged mice.

Study finds decrease in incidence of stroke, subsequent death

In a study that included a large sample of black and white U.S. adults from several communities, rates of stroke incidence and subsequent death decreased from 1987 to 2011, with decreases varying across age-groups, according to a study in the July 16 issue of JAMA.
