A research article to be published June 21, 2009 in the World Journal of Gastroenterology addresses this question. The research team lead by Dr. Gabriela Beatriz Acosta, observed that the activity of GS was increased in the hippocampus in PH rats. There was a significant decrease in glutamate uptake in both brain areas, which was more marked in the hippocampus. The decrease in glutamate uptake might be caused by deficient transport function and persistent glutamate activity, which is not metabolized.

SALT LAKE CITY, June 29, 2009 – Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it.
LA JOLLA, CA— Alcohol's inebriating effects are familiar to everyone. But the molecular details of alcohol's impact on brain activity remain a mystery. A new study by researchers at the Salk Institute for Biological Studies brings us closer to understanding how alcohol alters the way brain cells work.
Doctors may get a new arsenal for meningitis treatment and the war on drug-resistantbacteria and fungal infections with novel peptide nanoparticles developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN) of Singapore and reported in Nature Nanotechnology.
The stable bioengineered nanoparticles devised at IBN effectively seek out and destroy bacteria and fungal cells that could cause fatal infections and are highly therapeutic.
Hot or not? Men agree on the answer. Women don't.
There is much more consensus among men about whom they find attractive than there is among women, according to a new study by Wake Forest University psychologist Dustin Wood.
The study, co-authored by Claudia Brumbaugh of Queens College, appears in the June issue of the Journal of Personality and Social Psychology.
CHAMPAIGN, Ill. — When a zebra finch hears a new song from a member of its own species, the experience changes gene expression in its brain in unexpected ways, researchers report. The sequential switching on and off of thousands of genes after a bird hears a new tune offers a new picture of memory in the songbird brain.
Researchers have found that the anti-malarial drug quinine can block a cell's ability to take up the essential amino acid tryptophan, a discovery that may explain many of the adverse side-effects associated with quinine. Once confirmed, these findings would suggest that dietary tryptophan supplements could be a simple and inexpensive way to improve the performance of this important drug.
EVANSTON, Ill. --- To many, New York Gov. Eliott Spitzer's fall from grace seemed to make no sense at all. But a new Northwestern University study offers provocative insights that possibly could relate to why the storm trooper of reform -- formerly known as the Sheriff of Wall Street -- seemingly went from saint to sinner overnight.
The study suggests that people with ample moral self-worth in one aspect of their lives can slip into immorality or opposite behavior in other areas -- their abundant self-esteem somehow pushing them to balance out all that goodness.
New Orleans, LA – Research lead by Dr. Nicolas Bazan, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, identifying an enzyme that makes neuroprotectin D1 which specifically and selectively protects retinal cells key for vision, will be published in the June 26, 2009 issue of the Journal of Biological Chemistry.
Washington, DC – Senators Joseph Lieberman (I-CT) and John Cornyn (R-TX) today introduced the Federal Research Public Access Act (FRPAA), a bill to ensure free, timely, online access to the published results of research funded by eleven U.S. federal agencies. The proposed bill is welcomed by the Alliance for Taxpayer Access, a coalition of research institutions, consumers, patients, and others formed to support open public access to publicly funded research.
DALLAS – June 26, 2009 – An enzyme that naturally occurs in the brain helps destroy the mutated protein that is the most common cause of inherited Parkinson's disease, researchers at UT Southwestern Medical Center have found.
Their study, using human cells, provides a focus for further research into halting the action of the mutated protein. One of the most famous carriers of the mutation is Google co-founder Sergey Brin, who wrote about it on his blog in 2008.
June 26, 2009 - (BRONX, NY) - A variation in a gene that is active in the central nervous system is associated with increased risk for obesity, according to an international study in which Albert Einstein College of Medicine of Yeshiva University played a major role. The research adds to evidence that genes influence appetite and that the brain plays a key role in obesity.
People in very early stages of Alzheimer's disease already have trouble focusing on what is important to remember, a UCLA psychologist and colleagues report.
"One of the first telltale signs of Alzheimer's disease may be not memory problems, but failure to control attention," said Alan Castel, UCLA assistant professor of psychology and lead author of the study.
In an article published in the June 25th edition of the journal Neuron, researchers at the Hotchkiss Brain Institute, University of Calgary, have found that synaptic plasticity, long implicated as a device for 'change' in the brain, may also be essential for stability.
Homeostasis, the body's own mechanism of regulating and maintaining internal balance in the body, is necessary for survival. Precisely how the brain pulls off this tricky balancing act has not been well appreciated.
In primates including ourselves, the ability to register where others are looking is key in social circles. And, according to a new report published online on June 25th in Current Biology, a Cell Press publication, the way our brains process gaze-direction is much more sophisticated than a simple eyes-right versus eyes-left.
In fact, the way our brains code another's gaze-direction can hinge on what we already believe about that person's mental state, the new evidence shows.
