Is this my finger? People can be easily tricked into believing an artificial finger is their own, shows a study published today [23 September] in The Journal of Physiology. The results reveal that the brain does not require multiple signals to build a picture body ownership, as this is the first time the illusion has been created using sensory inputs from the muscle alone. The discovery provides new insight into clinical conditions where body representation in the brain is disrupted due...

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...

Vibrations Felt On Skin May Aid In Tactile Display Innovation
2013-06-14 11:23:07

Brett Smith for redOrbit.com - Your Universe Online Electronic distractions that can be dangerous while driving, such as a GPS system or text message, have created a need to convey information in a non-visual way. MIT researcher Lynette Jones believes she has come up with a solution to that problem: tactile ℠displays´ that send information through vibrating pulses. "If you compare the skin to the retina, you have about the same number of sensory receptors, you just have...

The Itch Molecule
2013-05-24 08:20:02

April Flowers for redOrbit.com - Your Universe Online Using mouse models, researchers at the National Institutes of Health (NIH) have discovered a small molecule that is released in the spinal cord that triggers a process later experienced in the brain as the sensation of itch. The results of this study were published in a recent issue of Science. The molecule, natriuretic polypeptide b (Nppb), selectively plugs into a specific nerve cell in the spinal cord. This nerve cell sends...

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...

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...

Crocodiles And Alligators Are Actually Sensitive Creatures
2012-11-08 14:12:17

Brett Smith for redOrbit.com - Your Universe Online Crocodiles and alligators are well-known for being cold-blooded and having thick skin, but new research from a pair of Vanderbilt University scientists has shown that the ancient reptiles can be quite sensitive. More specifically, the scientists demonstrated that these reptilian predators have small pigmented domes that dot their skin-- conveying a sense of touch is even more responsive than that of humans, according to the pair´s...

Neurons And The Sense Of Touch
2012-10-26 18:26:58

Michael Harper for redOrbit.com — Your Universe Online The sense of touch is perhaps the most basic, most elementary of the senses. It´s how many living things learn, move and explore. Yet, according to W. Daniel Tracey, PhD, there´s still plenty left to be discovered when it comes to the sense of touch. “On a molecular level, touch is the most poorly understood of the senses,” said Dr. Tracey who is an associate professor of anesthesiology at Duke University...
