EMBL scientists uncover counterpart of cerebral cortex in marine worms Our cerebral cortex, or pallium, is a big part of what makes us human: art, literature and science would not exist had this most fascinating part of our brain not emerged in some less intelligent ancestor in prehistoric times. But when did this occur and what were these ancestors? Unexpectedly, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered a true counterpart of...

By David F. Salisbury Origin of DEET's repellent effect confirmed It now appears that the malaria mosquito needs more than one family of odor sensors to sniff out its human prey. That is the implication of new research into the mosquito's sense of smell published in the Aug. 31 issue of the online, open-access journal Public Library of Science Biology. The experiments described in the paper provide striking new evidence that Anopheles gambiae "“ the species of mosquito that spreads...

Two new studies reveal that the commonly used insect repellents DEET and citronellal each work through a dual stimulation of insect sensory systems. The research findings, published by Cell Press on August 26 in the journals Neuron and Current Biology, enhance our understanding of how insects respond to repellents and may lead to the discovery of improved compounds for controlling insect-borne disease. Insect pests pose a major threat to humans across the world. In addition to spreading...

Crafting a fragrance for detergents that leaves laundry smelling clean and fresh. Developing a room freshener, scented oil, or scented candle that whispers "cool spring air." Giving toothpaste or mouthwash a refreshing aftertaste that lingers and lingers. The process for putting the smell that sells into thousands of consumer products is much like composing a symphony, according to maestro fragrance designer Michael Papas, who spoke at the 240th National Meeting of the American Chemical...

Whether a fish likes to hunt down its food or wait for dinner to arrive is linked to the composition of its brain, a University of Guelph researcher has revealed. Prof. Rob McLaughlin has discovered that foraging behaviour of brook trout is related to the size of a particular region in the fish's brain. "We found that the fish that swim around in the open in search of food have larger telencephalons than the fish that sit along the shoreline and wait for food to swim by in the water column,"...

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...

It's no secret that sharks have a keen sense of smell and a remarkable ability to follow their noses through the ocean, right to their next meal. Now, researchers reporting online in the June 10th issue of Current Biology, a Cell Press publication, have figured out how the sharks manage to keep themselves on course. It turns out that sharks can detect small delays, no more than half a second long, in the time that odors reach one nostril versus the other, the researchers report. When the...

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...

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...
