For the first time, human stem cells have been coaxed into sensory interneurons, the cells that give us our sense of touch. The new protocol, developed by UCLA researchers, could be a step toward stem cell-based therapies to restore sensation in paralyzed people who have lost feeling in parts of their body. Sensory interneurons, a… Read more

Can you touch a finger to the tip of your nose with your eyes closed? Most of us can, thanks to a sense called proprioception, which tells us where our body parts are relative to each other and our environment. Not surprisingly, this sense is essential for normal movement and balance— walking, for instance. For… Read more

The perception of being inside your own body is not as self-evident as you might think. In a new study from Sweden’s Karolinska Institutet, neuroscientists created an out-of-body illusion in participants placed inside a brain scanner. They then used the illusion to perceptually ‘teleport’ the participants to different locations in a room and show that… Read more

Two forms of sensory information, the feel of an object and the position of your body in space, have long been thought to flow into the brain via different channels and be integrated in sophisticated processing regions. Now, with help from a specially devised mechanical exoskeleton that positioned monkeys’ hands in different postures, Johns Hopkins… Read more
