"Our data indicate that the brain becomes hypersensitive to rewards when this co-signaling of glutamate and dopamine does not function. Lower doses than normal are enough to increase the propensity to ingest the substance, and this is true of both sugar and cocaine," says Ã…sa Mackenzie, associate professor of neuroscience at Uppsala University and the researcher who led the study. Addiction disorders are a major social problem, and we lack sufficient knowledge of how they...

New tool will allow integrated, simultaneous study of behavior and brain function in animals Scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Stony Brook University, and collaborators have demonstrated the efficacy of a "wearable," portable PET scanner they've developed for rats. The device will give neuroscientists a new tool for simultaneously studying brain function and behavior in fully awake, moving animals. The researchers describe the tool and...

(Ivanhoe Newswire) -- A recent study finds a gene linked to attention deficit hyperactivity disorder (ADHD) leads to daydreaming.  Researchers believe these findings are the first to show "“ through brain scanning "“ the dissimilarities in the brain network relationships between individuals with this specific form of gene and others with a different form. "Our goal is to narrow down the function of candidate genes associated with ADHD, and in this study, we find this gene is...

Using fMRI, the scientists were able to watch competition between these brain areas Neuroscientists at Georgetown University Medical Center (GUMC) say brain scans show that a gene nominally linked to attention deficit hyperactivity disorder (ADHD) leads to increased interference by brain regions associated with mind wandering during mental tasks. Presented at the annual meeting of the Society for Neuroscience, these researchers believe their findings are the first to show, through brain...

(Ivanhoe Newswire) -- The first experimental evidence to directly support the idea that genetic differences make some people more susceptible to the addictive effects of alcohol and other drugs was provided in this study. The study compared the brain's response to long-term alcohol drinking in two genetic variants of mice. One strain lacked the gene for dopamine D2, a specific brain receptor that responds to dopamine. Dopamine is the brain's "feel good" chemical. It produces feelings of...

Researchers at the University of Copenhagen have succeeded in creating a model of the way the brain releases dopamine, an important chemical involved in transmitting signals between nerve cells. The model, the product of an interdisciplinary collaboration, will be an important tool in helping scientists understand how we learn and how the brain perceives reward and punishment. It is hoped that the model can be used to understand drug addiction and in the treatment of schizophrenia. In the...

Finding may provide new insights into the neurological basis of ADHD, learning deficits, and more Scientists at the California Institute of Technology (Caltech) have uncovered evidence of a primitive emotion-like behavior in the fruit fly, Drosophila melanogaster. Their findings, which may be relevant to the relationship between the neurotransmitter dopamine and attention deficit hyperactivity disorder (ADHD), are described in the December issue of the journal Neuron. The Drosophila brain...

Low levels of dopamine markers may underlie symptoms; implications for treatment A brain-imaging study conducted at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provides the first definitive evidence that patients suffering from attention deficit hyperactivity disorder (ADHD) have lower-than-normal levels of certain proteins essential for experiencing reward and motivation. "These deficits in the brain's reward system may help explain clinical symptoms of ADHD,...
