Salk Institute Salk scientists show that the little-known supportive cells are vital in cognitive function When you're expecting something—like the meal you've ordered at a restaurant—or when something captures your interest, unique electrical rhythms sweep through your brain. These waves are called gamma oscillations and they reflect a symphony of cells—both excitatory and inhibitory—playing together in an orchestrated way. Though their role has been debated, gamma waves...

NIH/National Institute of Neurological Disorders and Stroke NIH-funded researchers find brain tumor cells disrupt the brain's protective barrier, offering potential avenues for therapy Invading glioblastoma cells may hijack cerebral blood vessels during early stages of disease progression and damage the brain's protective barrier, a study in mice indicates. This finding could ultimately lead to new ways to bring about the death of the tumor, as therapies may be able to reach these...

Neurosurgeon Peter Nakaji has published four academic papers with colleagues, each discussing technology and the intraoperative diagnosis of brain tumors. Phoenix, AZ (PRWEB) June 17, 2014 Acclaimed neurosurgeon Peter Nakaji has joined with several of his colleagues to publish four academic papers discussing methods of diagnosing tumors in the human brain. These methods would allow for the diagnosis of tumors either in the operating room during brain surgery or shortly thereafter....

University of California - San Diego Some neurons turn to neighbors to help take out the trash It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego School of Medicine, The Johns Hopkins University School of Medicine and Kennedy Krieger Institute have discovered that some neurons transfer unwanted mitochondria – the tiny power plants inside cells – to supporting glial cells called astrocytes...

Three molecularly defined clusters could alter practice; 1 closely resembles deadly glioblastoma Comprehensive genomic analysis of low-grade brain tumors sorts them into three categories, one of which has the molecular hallmarks and shortened survival of glioblastoma multiforme, the most lethal of brain tumors, researchers reported at the American Association for Cancer Research Annual Meeting 2014. "The immediate clinical implication is that a group of patients with tumors previously...

UCLA study discovers potassium boost improves walking in mouse model Tweaking a specific cell type's ability to absorb potassium in the brain improved walking and prolonged survival in a mouse model of Huntington's disease, reports a UCLA study published March 30 in the online edition of Nature Neuroscience. The discovery could point to new drug targets for treating the devastating disease, which strikes one in every 20,000 Americans. Huntington's disease is passed from parent to child...

Researchers Create New Neurons In Brains And Spinal Cords Of Living Adult Mammals

UT Southwestern Medical Center UT Southwestern Medical Center researchers created new nerve cells in the brains and spinal cords of living mammals without the need for stem cell transplants to replenish lost cells. Although the research indicates it may someday be possible to regenerate neurons from the body's own cells to repair traumatic brain injury or spinal cord damage or to treat conditions such as Alzheimer's disease, the researchers stressed that it is too soon to know whether...

New research has revealed a previously unknown mechanism in the body which regulates a hormone that is crucial for motivation, stress responses and control of blood pressure, pain and appetite. The breakthrough could be used to design drugs to help fight health problems connected with these functions in the future. Researchers at the University of Bristol and University College London found that lactate – essentially lactic acid – causes cells in the brain to release more noradrenaline...

Study in human cells may improve ability to identify useful drug targets In most cases of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, a toxin released by cells that normally nurture neurons in the brain and spinal cord can trigger loss of the nerve cells affected in the disease, Columbia researchers reported today in the online edition of the journal Neuron. The toxin is produced by star-shaped cells called astrocytes and kills nearby motor neurons. In ALS, the death...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
