Ritalin boosts learning by increasing brain plasticity
Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning. view more (2010-03-08)
Snake venom charms science world
The King Cobra continues to weave its charm with researchers identifying a protein in its venom with the potential for new drug discovery and to advance understanding of disease mechanisms. view more (2010-03-08)
Critical brain chemical shown to play role in severe depression
The next advance in treating major depression may relate to a group of brain chemicals that are involved in virtually all our brain activity, according to a study published today in Biological Psychiatry. view more (2010-03-02)
Schizophrenia mouse model should improve understanding and treatment of the disorder
Scientists have created what appears to be a schizophrenic mouse by reducing the inhibition of brain cells involved in complex reasoning and decisions about appropriate social behavior. view more (2010-01-04)
Easily led 'ash-tray': Adolescent smokers prone to drug abuse
It is common knowledge that smoking is a health risk but why do teens become addicted to smoking more easily than adults? In an evaluation for Faculty of 1000 Biology, Neil Grunberg looks into why adolescents are more prone to substance abuse. view more (2009-12-11)
Cut out the (estrogen) middleman
Estrogen seems to act like a middleman in its positive effect on the brain, raising the possibility that future drugs may bypass the carcinogenic hormone altogether while reaping its benefits. view more (2009-12-09)
New Down syndrome treatment suggested by Stanford/Packard study in mice
At birth, children with Down syndrome aren't developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development. view more (2009-11-19)
Widely used cholesterol-lowering drug may prevent progression
Simvastatin, a commonly used, cholesterol-lowering drug, may prevent Parkinson's disease from progressing further. Neurological researchers at Rush University Medical Center conducted a study examining the use of the FDA-approved medication in mice with Parkinson's disease and found that the drug successfully reverses the biochemical, cellular and... view more...

Popular antidepressant associated with a dramatic increase in suicidal thoughts amongst men
Nortriptyline has been found to cause a ten-fold increase in suicidal thoughts in men when compared to its competitor escitalopram. These findings are published in the open access journal BMC Medicine. view more (2009-10-15)
Why one way of learning is better than another
A new study from the Montreal Neurological Institute and Hospital (The Neuro) of McGill University reveals that different patterns of training and learning lead to different types of memory formation. view more (2009-10-02)
Researchers find a key mechanism in the development of nerve cells
Chaos brews in the brains of newborns: the nerve cells are still bound only loosely to each other. view more (2009-09-30)
Genetic marker linked to problem behaviors in adults with developmental disabilities
A common variation of the gene involved in regulating serotonin and norepinephrine in the brain may be linked to problem behaviors in adults with developmental and intellectual disabilities, new research indicates. view more (2009-07-22)
Promising new treatment for Alzheimer's suggested based on Hebrew University research
Research carried out at the Hebrew University of Jerusalem has resulted in a promising approach to help treat Alzheimer's disease in a significant proportion of the population that suffers from a particularly rapid development of this disease. view more (2009-07-21)
One step closer to an artificial nerve cell
Scientists at the Swedish medical university Karolinska Institutet and Linköping University are well on the way to creating the first artificial nerve cell that can communicate specifically with nerve cells in the body using neurotransmitters. view more (2009-07-08)
Hepatic encephalopathy and prehepatic portal hypertension rat model
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. view more (2009-06-29)
Larvae shun the light
Drosophila larvae avoid light during the foraging stage of their development. Research published in the open access journal BMC Neuroscience shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior. view more (2009-06-23)
Mouse model of Parkinson's reproduces nonmotor symptoms
The classic symptoms of Parkinson's disease involve tremor, stiffness and slow movements. Over the last decade, neurologists have been paying greater attention to non-motor symptoms, such as digestive and sleep problems, loss of sense of smell and depression. view more (2009-06-23)
'Singing brains' offers epilepsy and schizophrenia clues
Studying the way a person's brain 'sings' could improve our understanding of conditions such as epilepsy and schizophrenia and help develop better treatments. view more (2009-05-20)
Constant sunlight linked to summer suicide spike
Suicide rates in Greenland increase during the summer, peaking in June. Researchers writing in the open access journal BMC Psychiatry speculate that insomnia caused by incessant daylight may be to blame. view more (2009-05-08)
Throwing the micro switch: MicroRNA may link smoking risk gene to neurobiology of addiction
During the past several years, significant progress has been made in identifying susceptibility genes for nicotine dependence through genetic linkage and association analyses. view more (2009-04-23)
