Study identifies mechanism to explain how the body responds to potentially threatening negative odors Anxious people have a heightened sense of smell when it comes to sniffing out a threat, according to a new study by Elizabeth Krusemark and Wen Li from the University of Wisconsin-Madison in the US. Their work´ is published online in Springer's journal Chemosensory Perception. The study is part of a special issue² of this journal on neuroimaging the chemical senses. In...

People born without a sense of smell experience higher social insecurity and increased risk for depression, according to a study published Mar. 21 in the open access journal PLoS ONE. The authors of the study, led by Ilona Croy of the University of Dresden Medical School in Germany, investigated 32 individuals born without a sense of smell, known as isolated congenital anosmia. They found that the non-smellers did not have significant deviations from the norm in terms of many daily...

Brain Handles Odors In A Different Way
2012-03-22 05:44:48

Researchers from the Stowers institute for Medical Research have traced individual odor molecules in the brain to create a new model of how our sense of smell works. While once thought to cluster related smells, researchers have know discovered that the brain reacts to smells in a broader sense. Previous research has shown that the brain handles the senses in a very orderly way. Things that we touch were thought to be mapped together in the somatosensory cortex, things that we heard...

How are 100 billion cells created, each with specific duties? The human brain is evidence that nature can achieve this. Researchers at Linköping University in Sweden have now taken a step closer to solving this mystery. "Knowledge about the mechanisms that diversify neurons and keep them diverse is necessary in order to cultivate and replace nerve cells in the future," says Mattias Alenius, Assistant Professor of Neuroscience, who has published his research breakthrough...

Study sheds light on how plants sniff out unhealthy neighbors to fight off infection People and animals are not the only ones who can smell. Plants are also able to perceive odors, but they process them in a very different way . While insects or mammals smell odors within a second of exposure, plants require much longer exposure times to respond. Then using this information, they react effectively to the odors emitted by infected or infested neighboring plants in order to increase their...

Activating the visual cortex improves our sense of smell A new study reveals for the first time that activating the brain's visual cortex with a small amount of electrical stimulation actually improves our sense of smell. The finding published in the Journal of Neuroscience by researchers at the Montreal Neurological Institute and Hospital - The Neuro, McGill University and the Monell Chemical Senses Center, Philadelphia, revises our understanding of the complex biology of the senses in...

A team of researchers from a Dutch university have linked the olfactory sense with improved long-term memory -- a condition known as "the Proust phenomenon" in honor of the French author's novel "In Search of Lost Time." According to Telegraph Science Correspondent Nick Collins, Utrecht University researchers Marieke B. J. Toffolo, Monique A. M. Smeets, and Marcel A. van den Hout recruited 70 female students and had them watch video footage "designed to provoke aversion," including traffic...

Caltech Researchers Identify Mechanism Behind Associative Memory by Exploring Insect Brains A key feature of human and animal brains is that they are adaptive; they are able to change their structure and function based on input from the environment and on the potential associations, or consequences, of that input. For example, if a person puts his hand in a fire and gets burned, he learns to avoid flames; the simple sight of a flame has acquired a predictive value, which in this case, is...

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...
