In two thousand and six a landmark paper described how the man had learnt to move a curser around a computer screen, control a television and use robotic arms and hands. The study was co led by lee hockburg, a nero scientist and critical care nerologist at brown university in providence, rhode island. Hockberg adds today's b c i users have much finer control and access to a wider range of skills. In part, this is because researches began to implant multiple b c is in different brain areas of the user and devised new ways to identify useful signals. But hogburg says the biggest boost has come from machine learning, which has improved the ability
