Stowers investigators reveal a developmental switch in targeting capacity of olfactory neurons The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor and all neurons with the same receptors are connected to the same spot, a glomerulus, in the brain. This convergence, or wiring pattern, is often described as an...

Scientists at The Scripps Research Institute (TSRI) have discovered an important mechanism underlying sensory feedback that guides balance and limb movements. La Jolla, California (PRWEB) March 13, 2014 Scientists at The Scripps Research Institute (TSRI) have discovered an important mechanism underlying sensory feedback that guides balance and limb movements. The finding, which the TSRI team uncovered in fruit flies, centers on a gene and a type of nerve cell required for detection of...

Photoreactive compounds developed by LMU scientists directly modulate nerve-cell function, and open new routes to the treatment of neurological diseases, including chronic pain and certain types of visual impairment. All modes of sensory perception are based on communication between nerve cells. Both the response to the primary stimulus and the transmission of the resulting signal depend on the function of specialized receptor proteins that are associated with the surface membranes of...

Scientists have identified a channel present in many pain detecting sensory neurons that acts as a 'brake', limiting spontaneous pain. It is hoped that the new research, published today [22 January] in the Journal of Neuroscience, will ultimately contribute to new pain relief treatments. Spontaneous pain is ongoing pathological pain that occurs constantly (slow burning pain) or intermittently (sharp shooting pain) without any obvious immediate cause or trigger. The slow burning pain is the...

Smell Processes In Our Brain Better Understood Through Locust Study
2013-11-26 09:53:56

April Flowers for redOrbit.com - Your Universe Online Environmental stimuli often trigger our sense of smell before we exhibit any other response. Smells trigger neurons in our brains that alert us to take action, but there are often more than one odor in our environments at any given time. Barani Raman, PhD, of the School of Engineering & Applied Science at Washington University in St. Louis, wanted to answer the question of how our brain processes multiple odors received...

Researchers develop novel method to image worm brain activity and screen early stage compounds aimed at treating autism and anxiety. Worcester, MA (PRWEB) November 14, 2013 A research team at Worcester Polytechnic Institute (WPI) and The Rockefeller University in New York has developed a novel system to image brain activity in multiple awake and unconstrained worms. The technology, which makes it possible to study the genetics and neural circuitry associated with animal behavior, can also...

Origins Of Our Smell Cells Pinpointed By Scientists
2013-03-26 08:09:14

redOrbit Staff & Wire Reports - Your Universe Online Biologists at the California Institute of Technology (Caltech) have identified the origin of olfactory nerve cells, finding that neural-crest stem cells — multipotent, migratory cells unique to vertebrates that give rise to many structures in the body — play a key role in building olfactory sensory neurons in the nose. When human noses detect a scent, two types of sensory neurons are at work. These neurons are...

Turning Off The Cold: Neuroscientists Remove Chilly Protein From Skin
2013-02-13 07:59:08

Lawrence LeBlond for redOrbit.com - Your Universe Online Are you tired of being cold all the time? Do you wish you could turn the cold off at the push of a button? Well neuroscientists from the University of South Carolina (USC) may have some good news for you. It seems this group of researchers, led by David McKemy, associate professor of neurobiology in the USC Dornsife College of Letters, Arts and Science, have been able to isolate chilliness at the cellular level, identifying a...

Molecule That Converts Sound Into Brain Signals Found
2012-12-07 12:39:03

April Flowers for redOrbit.com - Your Universe Online Finding the exact genetic code that programs the ear´s machinery for responding to sound waves and converting them into electrical impulses in the inner ear has been something of a holy grail for the scientists who study the genetics of hearing and deafness. A new study from The Scripps Research Institute (TSRI) has brought this search to fruition by identifying a critical component of the ear-to-brain conversation. This...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
