Touch Receptors In Skin Distinguish Textures Via Vibrations
2013-10-01 07:19:43

April Flowers for redOrbit.com - Your Universe Online Humans can distinguish between fine textures, such as silk or satin, through vibrations, a new study has found. These vibrations are picked up by two separate sets of nerve receptors in the skin and is relayed to the brain. Previously, studies have shown that course textures like Braille dot patterns are encoded by receptors that are densely packed into the primate fingertip. There is a correspondence between the spatial layout of...

The Right Temperature Makes Tasty Treat For Fruit Flies

April Flowers for redOrbit.com - Your Universe Online Scientists call it the Goldilocks Principle. Animals can survive and breed only if the temperature is just right -- too hot and they will overheat; too cold and they will freeze. Animals have evolved very sensitive temperature sensors, which allow them to detect the relatively narrow margin in which they can survive. Until recently, very little was known about how these sensors worked. A new study from Brandeis University has...

Various areas of the brain process our sensory experiences. How the areas of the cerebral cortex communicate with each other and process sensory information has long puzzled neuroscientists. Exploring the sense of touch in mice, brain researchers from the University of Zurich now demonstrate that the transmission of sensory information from one cortical area to connected areas depends on the specific task to solve and the goal-directed behavior. These findings can serve as a basis for an...

Star-Nosed Mole Reveals Mysteries Of Touch And Pain Sensing Molecules
2013-01-31 12:23:49

Alan McStravick for redOrbit.com — Your Universe Online Located just about an inch above the human elbow is one of the most sensitive patches of skin on our body. An excess of nerve endings in this region means just a light pinch will have even those with the highest pain thresholds flinching and begging for mercy. But humans are not even in the running when it comes to hyper-sensitivity on the skin. Another mammal, the star-nosed mole (named for the star-shaped tip of its snout),...

When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then up and down until you find the metal or plastic plate of the switch. During the process you use your sense of touch to develop an image in your mind of the wall´s surface and make a better guess for where the switch is. Sliman Bensmaia, PhD, assistant professor of organismal biology...

Mechanisms Behind Response To Gentle Touch Discovered
2012-12-10 05:47:22

redOrbit Staff & Wire Reports - Your Universe Online A team of University of California, San Francisco (UCSF) researchers has reportedly discovered the group of nerve cells responsible for communicating the sensation of gentle touch in fruit flies -- and possibly in humans and other organisms as well -- potentially shedding light on one of most mysterious senses in all of biology. In their research, which has been published online by the journal Nature, the UCSF researchers studied...
