The details of the experiment are laid out in a report in the current issue of the journal Nature. Study co-author Krishna Shenoy, a Howard Hughes Medical Institute investigator at Stanford University, says this method appears to be more potentially powerful than similar studies that have attempted to translate speech rather than handwriting. "Right now, other investigators can achieve about a 50-word dictionary using machine learning methods when decoding speech," Shenoy said in a statement. "By using handwriting to record from hundreds of individual neurons, we can write any letter and thus any word which provides a truly 'open vocabulary' that can be used in most any life situation."
