New research, published in the journal Development, by Dr. Anthony-Samuel LaMantia, professor of Pharmacology & Physiology and director of the newly formed GW Institute for Neuroscience, and his colleagues have identified the stem cells that generate three critical classes of nerve cells "“ olfactory receptors (ORNs), vomeronasal (VRNs) and gonadotropin releasing hormone (GnRH) neurons "“ that are responsible for enabling animals and humans, to eat, interact socially and...

Popular zinc-based nasal gels and sprays sold over-the-counter as common cold remedies are ineffective, and can even cause the loss of smell, according to a study published Monday. Clinical trials of the zinc-based therapies showed they did not prevent or reduce the duration of common colds, and were linked to a loss of smell, the study's authors found. "In addition to concerns regarding the efficacy of intranasal zinc therapy, increasing evidence indicates that this medication may be linked...

Impaired ability to detect odors and irritants 2 years after buildings' collapse New research from the Monell Center and collaborating institutions reports that workers exposed to the complex mixture of toxic airborne chemicals following the 9/11 disaster had a decreased ability to detect odors and irritants two years after the exposure. "The nose performs many sensory functions that are critical for human health and safety," said lead author Pamela Dalton, PhD, MPH, an environmental...

The findings provide clues to how our brains work Scientists from The Scripps Research Institute have found a specific chemical compound secreted by many predators that makes mice behave fearfully. The research helps scientists better understand animal behavior, and may eventually lead to new insights into how sensory information is processed in human brains. The research was published in the prestigious journal Cell on May 14, 2010. "We're interested in how the brain can be hardwired to...

Heidelberg neuroscientists verify for the first time the function of inhibiting communication / Published in "Neuron" Whether different odors can be quickly distinguished depends on certain synapses in the brain that inhibit nerve stimulation. The researchers in Professor Dr. Thomas Kuner's team at the Institute of Anatomy and Cell Biology at Heidelberg University Medical School and Dr. Andreas Schäfer at the Max Planck Institute for Medical Research have shown that mice in which a...

Traditional Chinese acupuncture (TCA), where very thin needles are used to stimulate specific points in the body to elicit beneficial therapeutic responses, may be an effective treatment option for patients who suffer from persistent post- viral olfactory dysfunction (PVOD), according to new research in the April 2010 issue of Otolaryngology "“ Head and Neck Surgery. Olfactory dysfunction can arise from a variety of causes and can profoundly influence a patient's quality of life. The...

Yale study may lead to better traps, repellents Yale University researchers have found more than two dozen scent receptors in malaria-transmitting mosquitoes that detect compounds in human sweat, a finding that may help scientists to develop new ways to combat a disease that kills 1 million people annually. These olfactory receptors in the mosquito Anopheles gambiae offer scientists potential new targets for repelling, confusing or attracting into traps the mosquitoes that spread a disease...

The vomeronasal organ (VNO) is an odor detection system that mediates many pheromone-sensitive behaviors. Vomeronasal sensory neurons (VSNs), located in the VNO, are the initial site of interaction with odors and pheromones. How an individual VSN transduces chemical signals into electrical signals, however, has been a mystery. In the January 2010 issue of the Journal of General Physiology (www.jgp.org), researchers from the University of Vermont show that a Ca 2+ -activated chloride current...

As anyone suffering through a head cold knows, food tastes wrong when the nose is clogged, an experience that leads many to conclude that the sense of taste operates normally only when the olfactory system is also in good working order. Evidence that the taste system influences olfactory perception, however, has been vanishingly rare"”until now. In a novel study this week in Nature Neuroscience, Brandeis researchers report just such an influence. Neuroscientist Don Katz and colleagues...

Treatment with a glucocorticoid medication, either alone or in combination with Ginkgo biloba, appears to significantly improve the sense of smell in individuals with previous olfactory loss due to upper respiratory infections, according to a report in the October issue of Archives of Otolaryngology"“Head & Neck Surgery, one of the JAMA/Archives journals. Olfactory loss [loss of the sense of smell] is common and can be caused by head trauma, chronic sinonasal inflammation and viral...
