By Katrina Voss, Penn State A team of scientists led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State University, has peered inside neurons to discover an unexpected process that is required for regeneration after severe neuron injury. The process was discovered during Rolls's studies aimed at deciphering the inner workings of dendrites -- the part of the neuron that receives information from other cells and from the outside world. The research will...

Research provides insight into developmental disorders, including Williams syndrome Scientists at Emory University School of Medicine have uncovered how a structural component inside neurons performs two coordinated dance moves when the connections between neurons are strengthened. The results are published online in the journal Nature Neuroscience, and will appear in a future print issue. In experiments with neurons in culture, the researchers can distinguish two separate steps during...

Single neurons in the brain are surprisingly good at distinguishing different sequences of incoming information according to new research by UCL neuroscientists.The study, published today in Science and carried out by researchers based at the Wolfson Institute for Biomedical Research at UCL, shows that single neurons, and indeed even single dendrites, the tiny receiving elements of neurons, can very effectively distinguish between different temporal sequences of incoming information.This...

Cultured cells in microfluidic chambers enable systematic experiments at the synapse In order to be able to understand complex organs such as the brain or the nervous system, simplified model systems are required. A group of scientists led by the Frankfurt brain researcher Erin Schuman has successfully developed a novel method to grow cultured neurons in order to investigate basic mechanisms of memory. The researchers grew two separate populations of neurons in microfluidic platforms. These...

Göttingen-based Max Planck researcher decodes a molecular process that controls the growth of nerve cells Brain researcher Hiroshi Kawabe has discovered the workings of a process that had been completely overlooked until now, and that allows nerve cells in the brain to grow and form complex networks. The study, which has now been published in the journal Neuron, shows that an enzyme which usually controls the destruction of protein components has an unexpected function in nerve cells: it...

The early stages of Alzheimer's disease are thought to occur at the synapse, since synapse loss is associated with memory dysfunction. Evidence suggests that amyloid beta (AÃŽ²) plays an important role in early synaptic failure, but little has been understood about AÃŽ²'s effect on the plasticity of dendritic spines. These spines are short outgrowths of dendrites (extensions of neurons) that relay electrical impulses in the brain. A single neuron's dendrite...

Structurally, functionally different cell component replaces injured part Studies with fruit flies have shown that the specialized nerve cells called neurons can rebuild themselves after injury. These results, potentially relevant to research efforts to improve the treatment of patients with traumatic nerve damage or neurodegenerative disease, were presented at the American Society for Cell Biology (ASCB) 49th Annual Meeting, Dec. 5-9, 2009 in San Diego. An injured neuron's remarkable ability...

If the entrances and exits of freeways shut down, traffic all over the United States would come to a halt. In a similar situation, injuries to the brain can make it impossible for neurons to determine information input from output and impedes the ability of the nervous system to operate. In a recent report in The Journal of Neuroscience, researchers at Baylor College of Medicine and the University of Connecticut Health Center show that this is exactly what happens after nervous system...

Neurons are structurally complex, with specific parts of the cell responsible for information input and other parts responsible for information output. When neurons lose the ability to distinguish between inputs and outputs, the nervous system stops working. In a report published today in The Journal of Neuroscience, researchers at Baylor College of Medicine and the University of Connecticut Health Center show that this is exactly what happens after nervous system injury. "This is a new way...

Growth factors. They are the proteins that trigger a countless number of actions in cells. Drugs that increase or decrease certain growth factors have lead to treatments for cancer and cardiovascular diseases. Georgetown University Medical Center researchers say a new understanding of a growth factor implicated in some mental retardation disorders could lead to a novel treatment. Abnormalities in the number and shape of dendritic spines, the protrusions that allow communication between brain...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
