New Scientist -- In 2004, Erik Ramsey had an electrode implanted in his speech-motor cortex by Philip Kennedy’s team at Neural Signals, a company based in Duluth, Georgia, US, who hoped the signal from Ramsey’s cortex could be used to restore his speech. Interpreting these signals proved tricky, however. Fortunately, another team headed by Frank Guenther at Boston University, Massachusetts, US, has been working on the same problem from the opposite direction.
