Paleontologists have discovered that an improved sense of smell jumpstarted brain evolution in the ancestral cousins of present-day mammals.  The findings help explain why mammals evolved such large and complex brains, which in some cases ballooned 10 times larger than relative body size.  The researchers constructed fossils of two Early Jurassic Period mammals to provide evidence that the mammalian brain evolved in three major stages.  First by improvements in sense of smell...

New study suggests fragrances may enhance nightclub goers' experience Since the smoking ban in restaurants, bars and nightclubs, customers are more aware of unpleasant smells, such as body odors and the smell of old beer, that used to be masked by cigarette smoke. Now science is looking at how the introduction of pleasant ambient scents that hide unwanted odors might enhance the nightlife experience. According to Dr. Hendrik Schifferstein from Delft University of Technology in the...

A single interneuron controls activity adaptively in 50,000 neurons, enabling consistently sparse codes for odors The brain is a coding machine: it translates physical inputs from the world into visual, olfactory, auditory, tactile perceptions via the mysterious language of its nerve cells and the networks which they form. Neural codes could in principle take many forms, but in regions forming bottlenecks for information flow (e.g., the optic nerve) or in areas important for memory, sparse...

Scientists working in a laboratory at Vanderbilt University have potentially discovered a class of insect repellent that is 1000 times more effective than DEET and works against all types of insects. "It wasn't something we set out to find," said David Rinker, a graduate student who performed the study in collaboration with graduate student Gregory Pask and post-doctoral fellow Patrick Jones. "It was an anomaly that we noticed in our tests." Reported in the online edition of the Proceedings...

Most patients who have a reduced ability to smell or detect odors seem to attach less importance to the sense of smell in their daily lives than people with a normal olfactory function, according to a report in the April issue of Archives of Otolaryngology "“ Head & Neck Surgery, one of the JAMA/Archives journals. "Disorders of the sense of smell are common," the authors provide as background information in the article. "In the general population, hyposmia [reduced ability to smell]...

Scientists assemble genes involved in regulating olfaction in the antennae of a moth Insects have a highly sensitive sense of smell. Extremely low concentrations of odor molecules in the air are sufficient to be detected by receptor neurons on their antennae. Specific proteins, so-called receptor proteins, expressed in these neurons recognize the odors. The odor molecules bind to the receptors and produce chemical and electrical signals that are processed in the insect brain and eventually...

Findings show hormone causes people to sniff odors more An appetite-stimulating hormone causes people and animals to sniff odors more often and with greater sensitivity, according to a new study in the April 13 issue of The Journal of Neuroscience. The findings suggest ghrelin may enhance the ability to find and identify food. Researchers led by Jenny Tong, MD, and Matthias Tschöp, MD, at the University of Cincinnati found the appetite-related hormone also influences smell. The new study...

Birds are known in present time more for their vision and hearing than their sense of smell. However, a new study reveals that millions of years ago, their ancestors had a better sense for scents. Scientists at the University of Calgary, the Royal Tyrrell Museum and the Ohio University College of Osteopathic Medicine tested a long-standing view that the sense of smell for birds declined as they developed heightened senses of vision, hearing and balance for flight during evolution. The...

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...
