According to New Scientist magazine, the lirst to report on the Sony's
technique could be an improvement over an existing non-surgical method known as
transcranial magnetic stimulation. This activates nerves using rapidly changing ,
magnetic iields, but cannot be f on small groups of brain cells. 1
Niels Birbaumer, a neuroscientist at the University of Tuebingen in Germany, told
New Scientist he had looked at the Sony patent and "found it plausible." Birbaumer
himself has developed a device that enables disabled people to communicate by
reading their brain waves.
A Sony Electronics spokeswoman told the magazine that no experiments had been
conducted. and that the patent "was based on an inspiration that this may someday
be the direction that technology will take us." ’ ‘ · 1
