Study findings indicate a key step in the generation of white matter and understanding developmental disabilities Through the identification of a gene's impact on a signaling pathway, scientists at Children's National Medical Center continue to make progress in understanding the mechanics of a key brain developmental process: growth and repair of white matter, known as myelination. The study, published online in the September 2011 online edition of The Journal of Neuroscience, identified...

Animal study may suggest way to rescue cells from disease A protein linked to Alzheimer's disease kills nerve cells that detect odors, according to an animal study in the September 28 issue of The Journal of Neuroscience. The findings shed light on why people with Alzheimer's disease often lose their sense of smell early on in the course of the disease. "Deficits in odor detection and discrimination are among the earliest symptoms of Alzheimer's disease, suggesting that the sense of...

Microscopy technique used to observe activity of neurons like never before Like far away galaxies, powerful tools are required to bring the minute inner workings of neurons into focus. Borrowing a technique from materials science, a team of neurobiologists, psychiatrists, and advanced imaging specialists from Switzerland's EPLF and CHUV report in The Journal of Neuroscience how Digital Holographic Microscopy (DHM) can now be used to observe neuronal activity in real-time and in three...

New findings explain rapid signal transmission in eye's initial response to light A scientist from the Florida campus of The Scripps Research Institute has determined how a particular gene makes night vision possible. The study, which was published in the August 10, 2011 edition of The Journal of Neuroscience, focuses on a gene called nyctalopin. Mutations in the gene result in inherited "night blindness," a loss of vision in low-light environments. "Until now, our understanding of the role...

Animal study points to changes in brain that might help prevent cognitive decline A small amount of exercise shields older animals from memory loss following a bacterial infection, according to a study in the August 10 issue of The Journal of Neuroscience. The findings suggest moderate exercise may lead to several changes in the brain that boost its ability to protect itself during aging "” a period of increased vulnerability. In the new study, researchers led by Ruth Barrientos, PhD,...

New study demonstrates that a new class of drugs designed to treat narcolepsy will also be effective in reversing illness-induced lethargy A signaling system in the brain previously shown to regulate sleep is also responsible for inducing lethargy during illness, according to research conducted at Oregon Health & Science University Doernbecher Children's Hospital. This research is particularly meaningful because it implies that a new class of drugs developed to treat sleep disorders can...

You're trying to decide what to eat for dinner. Should it be the chicken and broccoli? The super-sized fast-food burger? Skip it entirely and just get some Rocky Road? Making that choice, it turns out, is a complex neurological exercise. But, according to researchers from the California Institute of Technology (Caltech), it's one that can be influenced by a simple shifting of attention toward the healthy side of life. And that shift may provide strategies to help us all make healthier...

Animal study suggests a common process for both the pleasurable and anxiety-reducing effects of nicotine Removing a protein from cells located in the brain's reward center blocks the anxiety-reducing and rewarding effects of nicotine, according to a new animal study in the July 27 issue of The Journal of Neuroscience. The findings may help researchers better understand how nicotine affects the brain. Nicotine works by binding to proteins called nicotinic receptors on the surface of brain...

Discovery puts scientists closer to human application Hibernation is an essential survival strategy for some animals and scientists have long thought it could also hold promise for human survival. But how hibernation works is largely unknown. Scientists at the University of Alaska Fairbanks have successfully induced hibernation at will, showing how the process is initiated. Their research is published in the July 26 issue of The Journal of Neuroscience. A hibernating animal has a reduced...

A person who drinks too much alcohol may be able to perform complicated tasks, such as dancing, carrying on a conversation or even driving a car, but later have no memory of those escapades. These periods of amnesia, commonly known as "blackouts," can last from a few minutes to several hours. Now, at Washington University School of Medicine in St. Louis, neuroscientists have identified the brain cells involved in blackouts and the molecular mechanism that appears to underlie them. They report...
