Creating the sense of touch… Feeling trapped…
Researchers have, for the first time, coaxed human stem cells to become sensory interneurons – the cells that give us our sense of touch. The new protocol could be a step toward stem cell-based therapies to restore sensation in paralyzed people who have lost feeling in parts of their body. (1) We want to sense.…

Cognitive ability. Longevity.
Investigators at The Feinstein Institute for Medical Research discovered dozens of new genetic variations associated with a person’s general cognitive ability. The findings, which were published online today in Cell Reports, have the potential to help researchers develop more targeted treatment for cognitive and memory disorders. “For the first time, we were able to use…

Health. Disease. Blurry lines…
Our genome is made up of 20,000 genes, all of which may cause disease. At present, 4,141 genes have been identified as being responsible for genetic abnormalities, leaving around 16,000 genes with unknown implication in disease. Researchers from the University of Geneva (UNIGE), Switzerland, — working in collaboration with scientists from Pakistan and the USA…

Re-mapping the brain… Moving mountains…
Targeted motor and sensory reinnervation (TMSR) is a surgical procedure on patients with amputations that reroutes residual limb nerves towards intact muscles and skin in order to fit them with a limb prosthesis allowing unprecedented control. By its nature, TMSR changes the way the brain processes motor control and somatosensory input; however, the detailed brain…

Phantom reality… Affecting reality…
In breakthrough research led by neuroscientist Olaf Blanke and his team at EPFL, Switzerland, the scientists show that phantom body pain can be reduced in paraplegics by creating a bodily illusion with the help of virtual reality. The results are published in Neurology. “We managed to provoke an illusion: the illusion that the subject’s legs…
