Returning veterans with major limb injuries Veterans who sustained major limb injuries during combat reported little improvement in symptoms of depression, anxiety, post-traumatic stress disorder (PTSD) and other mental-health problems up to 2 years post injury, according to research presented today. In contrast, pain showed the most improvement 3-6 months after acute hospitalization, and then leveled off after 1 year. The investigative team, led by Rollin M. Gallagher, MD, MPH, reported...

Eating With Your Eyes
2013-04-12 09:00:49

Brett Smith for redOrbit.com - Your Universe Online It has been said that people “eat with their eyes” before taking their first bite of any meal and a new study presented at the 245th National Meeting & Exposition of the American Chemical Society (ACS) suggests that the eyes can be even more important than the tongue when it comes to perceiving the flavors of foods. "There have been important new insights into how people perceive food flavors," said Cornell...

Phantom Limb Sensations Replicated In Non-Amputees
2013-04-12 07:57:14

[ Watch the Video: Scientists Create Phantom Sensations in Non-Amputees ] redOrbit Staff & Wire Reports - Your Universe Online While many people who have had an arm or a leg amputated have described experiencing the sensation of having a “phantom limb,” a team of neuroscientists from Karolinska Institutet in Sweden has managed to duplicate the phenomenon with people who have not had a limb amputated. Writing in the Journal of Cognitive Neuroscience, lead author Arvid...

Challenging The Brain's Visual System In New Environments
2013-04-12 05:12:08

redOrbit Staff & Wire Reports - Your Universe Online When people escape from the grind of their day-to-day lives and travel to remote, tranquil places, they often claim to “turn off” their brains so that they can soak in the calm, relaxing environment. Despite how restful things might seem, however, new research from the Salk Institute for Biological Studies in California reveals that a person´s mind — and more specifically, their visual system — is working...

Brain Imaging May Provide First Objective Measure Of Pain
2013-04-11 12:28:13

Brett Smith for redOrbit.com - Your Universe Online Physicians are often concerned about pain their patients may be experiencing, but without a way to quantify it, the experience of pain can be somewhat subjective and abstract. According to a new report in The New England Journal of Medicine, a group of American researchers has set out to determine how much pain a person is experiencing by looking at the brain´s reaction to it. Using Functional magnetic resonance imaging (fMRI),...

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...

Researchers at King's College London have uncovered how the human ear is formed, giving clues as to why children are susceptible to infections such as glue ear. The work was funded by the UK Medical Research Council and published today in the journal Science. It is estimated that one in five children around the age of two will be affected by glue ear, a build-up of fluid in the middle ear chamber. This part of the ear contains three tiny bones that carry sound vibrations from the eardrum...

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...

Ear
2013-04-30 13:31:11

The ear is an organ from the auditory system that collects sounds, and also balances and enables body position. Formation and Orientation The ear can be broken down into the inner and outer ears. The outer part of the ear is the visible flap (auricle) and ear canal which collects sounds which create pressure that echoes through the middle ear. The inner ear, however, is embedded in the temporal bone. There are hollow areas of the inner ear that are filled with liquids and hair cells...
