Silk implants are becoming the way of the future as far as brain implants are concerned, due to their paradoxically high resiliency and ability to dissolve. By combining them with nanoelectric circuits or drugs, scientists are exploring several possible applications, ranging from communications devices to control prosthetics and machines to medicinal devices that could treat disabilities and mental illnesses.
And according to a recent study released by the National Institutes of Health, treating epilepsy is just the latest application. According to the study, when administered to a series of epileptic rats, the treatment led to the rats experiencing far fewer seizures. What’s more, this new treatment represents something entirely new in terms of treatment of neurological disorder.
For starters, Rebecca L. Williams-Karneskyand and her colleagues used the silk implants for a timed-release therapy in rats experiencing epileptic seizures. Working on the theory that people with epilepsy suffer from a low level of adenosine – a chemical that the brain releases naturally to suppress seizures (and also perhaps movement during sleep) – they soaked the silk implants before implanting them.
Those rats who recieved the silk brain implants still had seizures, but their numbers were reduced fourfold. The implant released the chemical for ten days before they completely dissolved. And with time and testing, the treatment could very easily be made available for humans. According to the study’s co-author, Detlev Boison:
Clinical applications could be the prevention of epilepsy following head trauma or the prevention of seizures that often — in about 50 percent of patients — follow conventional epilepsy surgery. In this case, adenosine-releasing silk might be placed into the resection cavity in order to prevent future seizures.
Between the timed release of drugs and nanoelectric circuits that improve neuroelasticity, recall and relaxation, brain implants are coming a long way. At one time, they were the province of cyberpunk science fiction. But thanks to ongoing research and development, they are quickly jumping from the page and becoming a reality.
Though they currently remain confined to medical tests and laboratories, experts agree that it will be just a few years time before they are commercially available. By sometime in the coming decade, medimachines and neural implants will probably become a mainstay, and neurological disorders a fully treatable phenomena.
