Change in neurons' responsiveness marks newly formed sensory associations during learning
During our waking hours, our brains are inundated with sensory information that shifts from one moment to the next. view more (2005-11-08)
A virus may contribute to certain psychiatric disorders
A virus that causes a fatal brain disease in horses and sheep may be linked to certain mental disorders in man, medical experts heard today (Wednesday 09 January 2002) during a joint meeting of the European Societies of Clinical and Veterinary Virology and the Society for General Microbiology at the Royal College of Physicians, London. view more (2002-01-07)
Neurotransmitters in biopolymers stimulate nerve regeneration
Research reported December 11 in the journal Advanced Materials describes a potentially promising strategy for encouraging the regeneration of damaged central nervous system cells known as neurons. view more (2007-12-12)
Researchers uncover mechanism of action of antibiotic able to reduce neuronal cell death in brain
Virginia Commonwealth University researchers have discovered how an antibiotic works to modulate the activity of a neurotransmitter that regulates brain functions, which eventually could lead to therapies to treat Alzheimer's disease, Huntington's disease, epilepsy, stroke, dementia and malignant gliomas. view more (2008-05-12)
Sex differences in the brain's serotonin system
A new thesis from he Swedish medical university Karolinska Institutet shows that the brain�s serotonin system differs between men and women. The scientists who conducted the study think that they have found one of the reasons why depression and chronic anxiety are more common in women than in men. view more (2008-02-14)
Huntington's disease problem start early
The damaging effects of the mutated protein involved in Huntington's disease take place earlier in cell life than previously believed, said researchers from Baylor College of Medicine in Houston in a report that appears in the current edition of the journal Neuron. view more (2008-01-10)
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)
Matrix fragments trigger fatal excitement
Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org). view more (2008-12-30)
Insulin's brain impact links drugs and diabetes
Insulin, long known as an important regulator of blood glucose levels, now has a newly appreciated role in the brain. view more (2007-10-17)
GABA halts stem cell production in the brain
Release of the neurotransmitter GABA by adult neuronal precursor cells that develop into neurons limits stem cell proliferation, according to a study at Yale School of Medicine in the September issue of Nature Neuroscience. view more (2005-09-02)
New findings show additional similarity between opiate and nicotine addiction
"That was good!" "Do it again." This is what the brain says when people use tobacco, as well as 'hard drugs' such as heroin. view more (2008-02-13)
Memantine appears effective and safe in moderate to severe Alzheimer's disease
Memantine, a drug approved for the treatment of Alzheimer disease, appears safe and effective in patients with moderate to severe cases of the condition, according to a study in the January issue of Archives of Neurology. view more (2006-01-10)
Childhood depression may encourage ecstasy use
Children with symptoms of anxiety and depression may have an increased tendency to use ecstasy in adolescence or young adulthood, finds a study published online by the BMJ today. view more (2006-02-24)
New Tools Developed for Studying Neurodegenerative Brain Disorders
Penn State researchers have created an elegantly simple model of an axon-the extension of a neuron that communicates with other neurons-and have used this model to reproduce a change in the axon's shape that is characteristic of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. view more (2006-03-22)
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)
Nature's weapon against nerve agents
An enzyme found naturally in the blood could help protect soldiers against the effects of the deadly nerve agent sarin, reports Cath O'Driscoll in the Society of Chemical Industry's magazine Chemistry & Industry, the magazine of the SCI. view more (2007-07-30)
Hormone irregularities linked to chronic migraine
Hormonal irregularities may explain why migraine becomes chronic, shows research in the Journal of Neurology Neurosurgery and Psychiatry. Around 3 per cent of the population are chronic migraineurs, suffering pounding headaches for around 15 days a month. Hourly blood samples were taken from 17 chronic migraine sufferers, three of whom were men.... view more... (2001-11-23)
Astrocytes and synaptic plasticity
By mopping up excess neurotrophic factor from neuronal synapses, astrocytes may finely tune synaptic transmission to affect processes such as learning and memory, say Bergami et al. view more (2008-10-13)

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)
