Why antidepressants don't work for so many
More than half the people who take antidepressants for depression never get relief. view more (2009-10-26)
Fine-tuning treatments for depression
New research clarifies how neurotransmitters like norepinephrine, serotonin, and dopamine, are regulated - a finding that may help fine-tune therapies for depression. view more (2009-10-19)
Live recordings of cell communication
A new advanced method for nano-scale imaging of vesicle-fusion - vesicles are biological nano-sized containers - could add to our understanding of diseases of the nervous system and viral infections. view more (2009-08-06)
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)
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)
UBC researchers develop new method to study gambling addictions
UBC researchers have created the world's first animal laboratory experiment to successfully model human gambling. view more (2009-06-17)
CSHL researchers unravel how a protein helps nerve cells recycle synaptic vesicles
Brain cells, or neurons, transmit electrical signals efficiently only when they recycle tiny cellular sacs that store signaling chemicals called neurotransmitters. view more (2009-06-03)
'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)
Tiny but toxic: MBL researchers discover a mechanism of neurodegeneration in Alzheimer's disease
Tiny, toxic protein particles severely disrupt neurotransmission and inhibit delivery of key proteins in Alzheimer's disease, two separate studies by Marine Biological Laboratory (MBL) researchers have found. view more (2009-03-27)
Search for blood pressure secrets reveals a surprising new syndrome
Yale researchers investigating the genetic causes of blood pressure variation have identified a previously undescribed syndrome associated with seizures, a lack of coordination, developmental delay and hearing loss. view more (2009-03-17)
Cholesterol-reducing drugs may lessen brain function, says ISU researcher
Research by an Iowa State University scientist suggests that cholesterol-reducing drugs known as statins may lessen brain function. view more (2009-02-24)
Protein that regulates hormones critical to women's health found in pituitary
University of Wisconsin-Madison researchers have solved the mystery surrounding a "rogue protein" that plays a role in the release of neurotransmitters and hormones in the brain. view more (2009-01-12)
MIT engineers show how tiny cell proteins generate force to 'walk'
MIT researchers have shown how a cell motor protein exerts the force to move, enabling functions such as cell division. view more (2008-11-25)
Bound by Attention: Bringing rats and humans together
When picking through a basket of fruit, it doesn't seem very difficult to recognize a green pear from a green apple. This is easy, thanks to "feature binding"- a process by which our brain combines all of the specific features of an object and gives us a complete and unified picture of it. view more (2008-11-19)
Pitt research identifies new target in brain for treating schizophrenia
Research from the University of Pittsburgh could expand the options for controlling schizophrenia by identifying a brain region that responds to more than one type of antipsychotic drug. view more (2008-11-06)
Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain. view more (2008-09-29)
Antidepressants need new nerve cells to be effective, UT Southwestern researchers find
Researchers at UT Southwestern Medical Center have discovered in mice that the brain must create new nerve cells for either exercise or antidepressants to reduce depression-like behavior. view more (2008-08-28)
UCLA researchers clarify function of glucose transport molecule
Researchers at the David Geffen School of Medicine at UCLA have solved the structure of a class of proteins known as sodium glucose co-transporters (SGLTs), which pump glucose into cells. view more (2008-07-07)
Scientists find how neural activity spurs blood flow in the brain
New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity. view more (2008-06-26)
Are Anxiety Disorders All in the Mind?
Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction. view more (2008-05-13)
