Neuronal cell cultures kept on the straight and narrow
An improved technique for culturing cells, developed at the National Institute of Standards and Technology (NIST), may enable new, fundamental insights into the behavior of neuronal cells.   view more (2006-05-26)

Foundation trusts threaten core NHS principles
The creation of foundation trusts by the UK government endanger one of the founding principles of the NHS - to provide equal care for equal need, argue doctors in this week's BMJ. The new Health and Social Care Bill abolishes government control of NHS trusts by turning them into foundation trusts -... view more (2003-10-22)

Brandeis researchers propose model of neural circuit underlying working memory
Our ability to understand speech or decide which fruit in the store is freshest depends on the brain's dexterity in integrating information over time.   view more (2005-12-21)

Study shows how daughter is different from mother
The mother-daughter relationship can be difficult to understand. Why are the two so different? Now a Northwestern University study shows how this happens. In yeast cells, that is.   view more (2008-08-19)

Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see.   view more (2006-09-21)

Cicardian system suffers and protects from prenatal cocaine exposure
Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin... view more (2007-07-11)

Researchers Discover New Factor in Nerve Regeneration
Researchers in Oxford University's Department of Human Anatomy have identified a factor involved in the regeneration of neurons in the central nervous system. The discovery and use of this factor could provide the basis for a reparative treatment for both brain and spinal cord injuries. Unlike... view more (2003-04-07)

Antidepressants enhance neuronal plasticity in the visual system
In the April 18 issue of Science, scientists from the Scuola Normale Superiore in Pisa, Italy and the Neuroscience Centre at the University of Helsinki, Finland, provide new information about the mechanism of action of antidepressant drugs.   view more (2008-04-18)

Bioluminescence at the service of a novel cerebral imaging technique
CNRS scientists in collaboration have developed a new technique for the in vivo imaging of neuronal function using bioluminescence, based on a GFP-aequorin fusion protein.   view more (2007-04-17)

Researchers link master regulator of innate immunity to the hypoxic response
Survival of all animals depends on their ability to withstand microbial infections and adapt to fluctuations in oxygen concentrations.   view more (2008-04-24)

Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity... view more (2007-04-05)

Nanowire arrays can detect signals along individual neurons
Opening a whole new interface between nanotechnology and neuroscience, scientists at Harvard University have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of live mammalian neurons.   view more (2006-08-25)

Researchers develop marker that identifies energy-producing centers in nerve cells
A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system.   view more (2007-02-02)

How does insulin influence resistin?
Obesity is a worldwide health problem directly linked to several diseases such as hypertension and type 2 diabetes. Resistin is a cysteine-rich hormone mainly secreted by adipose tissues and may form a biochemical link between obesity and type 2 diabetes.   view more (2008-01-17)

A molecule that protects from neuronal disorders
Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly - a form of mental retardation -, result from abnormal migration of nerve cells during the development of the brain.   view more (2007-09-17)

Zinc plays important role in brain circuitry
To the multitude of substances that regulate neuronal signaling in the brain and spinal cord add a new key player: zinc. By engineering a mouse with a mutation affecting a neuronal zinc target, researchers have demonstrated a central role for zinc in modulating signaling among the neurons.   view more (2006-11-27)

Neurological effects of childhood sleep apnea
In this study, Ann Halbower and colleagues from Johns Hopkins University School of Medicine looked at 19 children aged 6-16 y with OSA and compared them with 12 healthy controls.   view more (2006-08-22)

QBI neuroscientists make Alzheimer's disease advance
Queensland Brain Institute (QBI) neuroscientists at UQ have discovered a new way to reduce neuronal loss in the brain of a person with Alzheimer's disease.   view more (2008-06-10)

Nerve cells derived from stem cells and transplanted into mice may lead to improved brain treatments
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience.   view more (2008-06-25)

Insight into dopamine role suggests new treatment pathway for Parkinson's
Dopamine (DA) not only functions as a neurotransmitter, a chemical messenger between neurons by which one neuron triggers another, researchers have found.   view more (2006-10-19)

Alzheimer's-associated enzyme can disrupt neural activity in the brain
An enzyme involved in the formation of the amyloid-beta protein associated with Alzheimer's disease can also alter the mechanism by which signals are transmitted between brain cells, the disruption of which can cause seizures.   view more (2007-06-18)

Weill Cornell Team Discovers How Brain's Own tPA Helps Regulate Blood Flow to Neurons
The human brain contains its own store of a powerful enzyme (and stroke drug) called tissue plasminogen activator (tPA), which appears to be a key regulator of blood flow to brain cells, a team at the Weill Cornell Medical College in New York City reports.   view more (2008-01-18)

Opiates and cannaboids: the fight against pain
Opiates and cannaboids, apart from being drugs, have curative properties. Thus, opiates (morphine, methadone, etc.) have been used for some time as a pain-reducer and many cannaboids have also analgesic properties. Regarding their curative aspects, it is very important to know the effects produced... view more (2003-03-18)

Telling axons where to go - and grow
In a recent study, Dr. Ingolf Bach and colleagues from the University of Massachusetts Medical School, Worcester and the University of Hamburg (Germany) describe a novel role for the ubiquitin/proteosome protein degradation pathway in the regulation of local actin dynamics in neurons.   view more (2005-10-03)
