RESEARCHERS in the USA have developed a new algorithm to help create prosthetic devices that convert brain signals into action in patients who have been paralysed or had limbs amputated. Trauma and disease can lead to paralysis or amputation, reducing the ability to move or talk despite the capacity to think and form intentions. However, electronics can be used to monitor the neural signals that reflect an individual's intentions in order to drive a prosthesis or computer. Algorithms are used to translate the brain signal into a form the external device can use.
