For the treatment of chronic pain specialists have created an artificial nerve

A group of Swedish researchers headed by Amanda Jonsson University of Germany presented a new development that is able to transmit through the body of ions and molecules at the same rate at which it makes the nervous system. Artificial nerve is intended, in particular, in order to deal with chronic pain.

Experts say that its development opens the way for the creation of mechanisms of “talking with the human body in the same language”. Artificial nerve, or “ion pump,” as it was called by the scientists, capable to send to any part of the body’s gamma-aminobutyric acid — a chemical involved in controlling pain and is able to block nerve signals. Experts note that this is only one of the molecules that can be delivered to the body through their development.

On new technology, the researchers worked for over a decade. As noted, a year and a half ago, experts have already submitted the first version of “ion pump”, and with his help have managed to direct GABA directly into the spinal cord in laboratory mice. The mechanism, presented this time was more compact than the previous one, and it works faster. Experts say that it almost managed to reach the speed at which signals the body sends nervous system (the path between the synapses these signals overcome for 1-10 milliseconds).

In addition to chronic pain, we offer scientists the technology theoretically can effectively deal with epileptic seizures and symptoms of Parkinson’s disease. However, while the development still has many trials — yet in its current form on live cells it has not been tested. The researchers also noted that they planned some improvements.

On their study, the scientists said in the pages of Science Advances.
