An investigational treatment for an inherited form of Lou Gehrig´s disease has passed an early phase clinical trial for safety, researchers at Washington University School of Medicine in St. Louis and Massachusetts General Hospital report. The researchers have shown that the therapy produced no serious side effects in patients with the disease, also known as amyotrophic lateral sclerosis (ALS). The phase 1 trial´s results, available online in Lancet Neurology, also demonstrate...

Reading Into The Brain To Understand How Neurons Represent The World
2013-04-23 15:33:22

International School of Advanced Studies (SISSA) We know the world through the sensory representations within our brain. Such "reconstruction" is performed through the electrical activation of neural cells, the code that contains the information that is constantly processed by the brain. If we wish to understand what are the rules followed by the representation of the world inside the brain we have to comprehend how electrical activation is linked to the sensory experience. For this...

Study Finds Hot And Cold Senses Interact
2013-04-09 10:20:59

University of North Carolina Health Care A study from the University of North Carolina School of Medicine offers new insights into how the nervous system processes hot and cold temperatures. The research led by neuroscientist Mark J. Zylka, PhD, associate professor of cell biology and physiology, found an interaction between the neural circuits that detect hot and cold stimuli: cold perception is enhanced when nerve circuitry for heat is inactivated. "This discovery has implications for...

Your Nose Isn’t The Only Organ That Can Smell
2013-04-08 12:47:35

Brett Smith for redOrbit.com - Your Universe Online The nose is a highly specialized organ, and for years it has been assumed that it is the only part of the human body which is finely attuned to receiving and process odors. However, a new study presented at 245th National Meeting & Exposition of the American Chemical Society in New Orleans reported that heart, blood, lung and other cells have the same receptors for sensing odors that are present in the nose. "Our team recently...

Insect odorant receptors regulate their own sensitivity. Highly developed antennae containing different types of olfactory receptors allow insects to use minute amounts of odors for orientation towards resources like food, oviposition sites or mates. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now used mutant flies and for the first time provided experimental proof that the extremely sensitive olfactory system of fruit flies – they are able to...

Taste Perception: Connecting The Molecular Dots
2013-03-07 05:16:27

redOrbit Staff & Wire Reports - Your Universe Online A consortium of scientists has identified a new protein regulator of taste, findings that help unlock the mystery of exactly how cells transmit taste information to the brain for three out of the five primary taste types. The researchers identified CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception. The other two taste types, sour...

Phantom Pain In Amputees Linked To The Brain
2013-03-06 05:38:54

April Flowers for redOrbit.com - Your Universe Online A new brain imaging study from Oxford University reveals that the phantom pain many amputees feel in the missing limb is linked to changes in the brain that occur following amputation. Arm amputees who maintained strong representations of the missing hand in their brains — to the point where it was indistinguishable from persons with both hands — experienced the most phantom limb pain. The research team hopes that...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
