The synapse is a shotgun

...ch are critical for communication in the brain and nervous system. The "nano-map," which shows the tiny spines and valleys resolved at nanometer scale, or one-billionth of a meter, has already proven its worth in changing scientists' views of the synaptic landscape. Using the map as a guide, the research te...

Defect in gene causes 'neuralgic amyotrophy'

...Amyotrophy is a painful disorder of the peripheral nervous system. This heritable disease causes prolonged a... Neuralgic Amyotrophy, a painful disorder of the nervous system Hereditary Neuralgic Amyotrophy (HNA) is characterized by repeated attacks of pain in a sh...

Molecular miners find pain relief drugs from the sea

...is, pain generated inside the body (arising in the nervous system) as opposed to the other type of pain ?nociceptive pain ?which comes from the outside in, for example, a burn. Associate Professor Livett says neuropathic pain is the most difficult form to treat and typically responds poorly to conventional ...

Weight control protein may yield antiobesity drugs

...Rui. The hypothalamus is a key area in the central nervous system that integrates neuronal, hormonal, and nutrient-related signals to maintain body weight, he explained. Leptin is a hormone produced by fat that normally decreases food intake and increases energy expenditure. In many species, including human...

Genes linked to treatment resistance in children with leukemia

...for evidence of leukemia in each patient's central nervous system (CNS), a region that is vulnerable to infiltration by cancer cells. Genetic variations may have particular impact on how drugs penetrate the "blood-brain" barrier that protects the CNS. For patients in the high-risk arm, the VDR FokI genotype ...

New study shows SARS can infect brain tissue

Single gene is genetic switch for fly sexual behavior

...nate behaviors, which are a consequence of how the nervous system is built, should be any different. Indeed, I think that is what our work shows," he says. In a second Cell paper, Dickson and colleagues demonstrate that nerve cells expressing the fruitless gene are linked in a circuit in both males and fema...

UCLA scientists reveal how Nipah virus infects cells

...lining the blood vessels, Ephrin-B2 is critical to nervous system development and the growth of blood vessels in human and animal embryos. Ephrin-B2 is found in humans, horses, pigs and bats, which may explain why the infection can jump so easily from one species to another. Collaborating with the Universit...

How fish hear and make sounds at same time

...to be amazed by how similar the operation of their nervous system is to that of mammals," said Andrew Bass, professor of neurobiology and behavior at Cornell, and an author of the study published in the June 22 issue of the Journal of Neuroscience. "You don't need to study a mammal to understand what a mamma...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...tiple pathways relay visual input into the central nervous system for different types of processing," Ro said. "And our study also begins to shed light on the brain structures that are necessary for consciousness, with the primary visual cortex playing an essential role for visual awareness." The phenomen...

Dendritic cells offer new therapeutic target for drugs to treat MS and other autoimmune disease

...myelin protein sheath around nerves in the central nervous system. The drug had a similar effect on dendritic cells, causing most of them to die. In the mouse model, investigators found that more of the myelin sheath was preserved in mice treated with CEP-701 than those not treated. Small cautions that mas...
