Brain switch provides clues to drug addiction

In the quest to find the biological route of drug addiction, research at Cambridge University, UK, is revealing what makes some people more vulnerable than others. Speaking at Europe's major neuroscience conference in Geneva, Professor Barry Everitt described what they now believe causes the switch from occasional, 'recreational' use to a compulsive habit.

Stem cells help keep the brain healthy and active

For some years, scientists have been speculating over why stem cells exist in the brain, as brain regeneration is limited. A German team of neuroscientists believe these stem cells help keep the brain healthy and active.

Researchers identify brain cells related to fear - paves way for more effective PTSD treatments

The National Institute of Mental Health estimates that in any given year, about 40 million adults (18 or older) will suffer from some form of anxiety disorder, including debilitating conditions such as phobias, panic disorders and post-traumatic stress disorder (PTSD). It is estimated that nearly 15 percent of U.S. soldiers returning from Iraq and Afghanistan develop PTSD, underscoring the urgency to develop better treatment strategies for anxiety disorders.

The good and bad side of dopamine

The chemical dopamine induces both desire and dread, according to new animal research in the July 9 issue of The Journal of Neuroscience. Although dopamine is well known to motivate animals and people to seek positive rewards, the study indicates that it also can promote negative feelings like fear.

Genetic change in dopamine transporter supports a role for dopamine signaling in ADHD

A genetic change in the dopamine transporter - one of the brain's dopamine-handling proteins - makes it behave as if amphetamine is present and "run backward," Vanderbilt University Medical Center investigators report this week in The Journal of Neuroscience.

Spiritual effects of 'sacred mushrooms' appear to last more than a year

In a follow-up to research showing that psilocybin, a substance contained in "sacred mushrooms," produces substantial spiritual effects, a Johns Hopkins team reports that those beneficial effects appear to last more than a year.

Neural stem cell development may be linked to Autism

In a breakthrough scientific study published today in the Proceedings of the National Academy of Sciences, scientists at the Burnham Institute for Medical Research have shown that neural stem cell development may be linked to Autism.

Unique pheromone detection system uncovered by researchers

Researchers at UT Southwestern Medical Center have overturned the current theory of how a pheromone works at the molecular level to trigger behavior in fruit flies.

Nerve cells derived from stem cells may one day provide improved brain treatments

Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published in The Journal of Neuroscience.

Pitt awarded $2.5 million to model how the brain and immune system function in response to illness, infection

In an effort to promote the application of mathematics to medical treatment, researchers in the University of Pittsburgh's Department of Mathematics will undertake a $2.5 million project to create models of how the brain and immune system function and change over time in response to certain illnesses, infections, and treatment.

New discovery could lead to new treatments for Alzheimer's

Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.
