Angewandte Chemie: 3-D structure and hydrogen bridge pattern explained Banana, mango or apricot - telling these smells apart is no problem for the human nose. How the olfactory organ distinguishes such similar smells has been uncovered by an interdisciplinary team of researchers at the RUB. The scientists were the first to shed light on the dynamics of the three-dimensional structure of the binding site of an olfactory receptor. In so doing, they also found a characteristic pattern of...

PHILADELPHIA, Dec. 9, 2011 /PRNewswire-USNewswire/ -- Congressman Chaka Fattah (D-PA), the leading Democratic appropriator for scientific research and author of the just-enacted neuroscience research initiative, will visit two research laboratories in Philadelphia's University City Science Center on Monday morning and explore their cutting-edge research in the neurosciences. The labs are Monell Chemical Senses Center and The Children's Hospital of Philadelphia. Congressman Fattah is the...

Neuroscientists find genetic trigger that makes stem cells differentiate in nose epithelia University of California, Berkeley, neuroscientists have discovered a genetic trigger that makes the nose renew its smell sensors, providing hope for new therapies for people who have lost their sense of smell due to trauma or old age. The gene tells olfactory stem cells the adult tissue stem cells in the nose to mature into the sensory neurons that detect odors and relay that information to the...

One of the earliest known impairments caused by Alzheimer's disease - loss of sense of smell — can be restored by removing a plaque-forming protein in a mouse model of the disease, a study led by a Case Western Reserve University School of Medicine researcher finds. The study confirms that the protein, called amyloid beta, causes the loss. "The evidence indicates we can use the sense of smell to determine if someone may get Alzheimer's disease, and use changes in sense of smell to...

A new animal study suggests that with training, smell can improve In a new study scientists at NYU Langone Medical Center have shown that the sense of smell can be improved. The new findings, published online November 20, 2011, in Nature Neuroscience, suggest possible ways to reverse the loss of smell due to aging or disease. Smell is unique among our senses, explains Donald A. Wilson, PhD, professor of child and adolescent psychiatry at NYU Langone Medical Center and senior research...

Green Chem Direct's New Pet Safe Odor Control and Cleaner is a safe and effective biological odor neutralizer through natural enzyme activity. Pet Safe degrades and eliminates the source of the odor. Pet Safe is designed for use on multiple surfaces, indoors and outdoors, to destroy odors associated with urine, feces, vomit, drool, mold, mildew and other pet messes. Landenberg, PA (PRWEB) November 16, 2011 Green Chem Direct developed Pet Safe Odor Control and Cleaner to be an effective and...

Tiny regulatory elements in the genome regulate the probability that olfactory sensory neurons choose a particular odorant receptor gene for expression The olfactory sensory neurons in the nasal mucosa perceive the myriad smells in the air with the aid of odorant receptors. Each sensory neuron chooses one and only one receptor gene for expression. The probability that a particular receptor gene is chosen for expression determines how many olfactory sensory neurons in total produce this...

Motherhood is associated with the acquisition of a host of new behaviors that must be driven, at least in part, by alterations in brain function. Now, new research published by Cell Press in the October 20 issue of the journal Neuron provides intriguing insight into how neural changes associated with the integration of odors and sounds underlie a mother's ability to recognize and respond to distress calls from her pups. "We know that distinct brain changes are linked with motherhood, but...

Researchers find that the brain smells what it expects rather than what it sniffs In the moments before you “stop and smell the roses,” it´s likely your brain is already preparing your sensory system for that familiar floral smell. New research from Northwestern Medicine offers strong evidence that the brain uses predictive coding to generate “predictive templates” of specific smells -- setting up a mental expectation of a scent before it hits your nostrils....

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...

Nose
2013-03-05 14:47:26

The nose is the organ that extends outward in the middle of the face between the eyes and mouth. Formation and Orientation The shape and look of the nose is dependent on the ethmoid bone and the nasal septum which is the cartilage that separates the two nostrils. The evolutionary hypotheses of nose development in humans propose that noses are alterations of the angles of the skull because of bipedalism. Because of the change in diet that has come with modern time and the change of...
