University of California - San Diego Researchers discover how neurons equalize between excitation and inhibition Researchers at the University of California, San Diego School of Medicine have discovered a fundamental mechanism by which the brain maintains its internal balance. The mechanism, described in the June 22 advanced online publication of the journal Nature, involves the brain's most basic inner wiring and the processes that control whether a neuron relays information to other...

We've all heard the saying "you can't teach an old dog new tricks." Now neuroscientists are beginning to explain the science behind the adage. For years, neuroscientists have struggled to understand how the microcircuitry of the brain makes learning easier for the young, and more difficult for the old. New findings published in the journal Nature by Carnegie Mellon University, the University of California, Los Angeles and the University of California, Irvine show how one component of the...

Salk-Gladstone Study Helps Scientists Decode Circuitry That Guides Brain Function

Salk Institute The power of the brain lies in its trillions of intercellular connections, called synapses that together form complex neural "networks." While neuroscientists have long sought to map these individual connections to see how they influence specific brain functions, traditional techniques have been unsuccessful. Now, scientists at the Salk Institute and the Gladstone Institutes, using an innovative brain- tracing technique, have found a way to untangle these networks. These...

Where the nonspecific thalamus meets the prefrontal cortex Inside the brains of mice and men alike, a relatively big football-shaped region called the thalamus acts like a switchboard, providing the prefrontal cortex, the part that does abstract thinking and decision-making, with most of its information. The thalamus's responsibility even includes helping the prefrontal cortex to maintain consciousness and arousal. Essential as this "thalamocortical" partnership is, neuroscientists have...

Skin Cells Create Stem Cells In Huntington Disease Study
2012-06-29 09:13:31

Connie K. Ho for redOrbit.com — Your Universe Online In 1993, the autosomal dominant gene mutation responsible for Huntington´s Disease (HD) was discovered. However, no treatments are known to slow its progression. New research may pave the way to better understanding of the disease. Researchers at Johns Hopkins recently announced that they were able to produce stem cells from skin cells from a person who had severe, early-onset form of HD; the cells were then changed into...

20 mouse lines provide views of cortical GABA neurons not previously possible A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in creating what amounts to a GPS system for locating and tracking a vital class of brain cells that until now has eluded comprehensive identification, particularly in living animals. The cells in question are the class of neurons that release the neurotransmitter called GABA (gamma aminobutyric acid). GABA neurons function to...

Mount Sinai researchers have discovered how cocaine corrupts the brain and becomes addictive. These findings"”the first to connect activation of specific neurons to alterations in cocaine reward"”were published in Science on October 15. The results may help researchers in developing new ways of treating those addicted to the drug. Led by Mary Kay Lobo, PhD, Postdoctoral Fellow in the Department of Neuroscience at Mount Sinai School of Medicine and first author of the study,...

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...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
