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...

From a new study in Biological Psychiatry A significant obstacle to progress in understanding psychiatric disorders is the difficulty in obtaining living brain tissue for study so that disease processes can be studied directly. Recent advances in basic cellular neuroscience now suggest that, for some purposes, cultured neural stem cells may be studied in order to research psychiatric disease mechanisms. But where can one obtain these cells outside of the brain? Increasingly,...

Fruit flies don't have noses, but a huge part of their brains is dedicated to processing smells. Flies probably rely on the sense of smell more than any other sense for essential activities such as finding mates and avoiding danger.  UW-Madison researchers have discovered that a gene called distal-less is critical to the fly's ability to receive, process and respond to smells. As reported in the current issue of the Proceedings of the National Academy of Sciences, the scientists...

There is an increasing trend towards nimbyism — people welcome developments in principle, so long as they are “not in my back yard”.  But just how big is a back yard?  The answer depends on a number of factors and Günther Schauberger of the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) has now developed a mathematical model to calculate appropriate distances from residential areas for livestock building to be sited.  The model is...

The problem in biology of how to identify the promoters of olfactory receptor genes (>1000 genes) has remained unsolved due to the difficulty of purifying sufficient material from the olfactory epithelium. Researchers at the RIKEN Omics Science Center, collaborating with scientists from Italy, Norway, the United States, the United Kingdom and Germany, have now solved this problem using nanoCAGE technology, which enables comprehensive analysis of transcription start sites (TSSs) from tiny...

Compared to Neanderthals, modern humans have a better sense of smell Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain...

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...

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...

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...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
