'Thinking cap' controls prosthetic arm with thoughts, not surgery

The power to regulate prosthetics with solely the facility of your thoughts has been round for some time, however it sometimes requires management electronics implanted immediately into the affected person. With this new, non-invasive technique developed on the College of Houston, nevertheless, amputees can command their robotic limbs with out surgical procedure. As an alternative of implants, the UH system makes use of a wearable “considering cap” (aka an EEG) that screens mind exercise externally by way of the scalp. A mind-machine interface (BMI) then interprets these mind waves and converts that intention into mechanical movement. Principally, the affected person thinks about choosing up an object, the BMI acknowledges the intention after which tells an hooked up prosthetic to take action. Even at this early stage of improvement, College of Houston researchers have gotten the system to work correctly eighty % of the time.

The staff’s findings have been revealed this week within the journal Frontiers in Neuroscience. It is reportedly the primary time anyone’s been capable of get an EEG and BMI to work this nicely with a multi-fingered prosthetic hand. The researchers hope that this new system will keep away from the pitfalls of implanted controls (like potential infections or rejection by the physique) whereas offering sufferers with extra correct and intuitive management. Not solely ought to this result in higher and extra responsive prosthetic units, the collected knowledge on how our brains talk with our limbs might additionally enhance remedy for individuals affected by stroke or spinal accidents.
