The field workers

摘要

Charles Epstein, a neurologist from Emory University in Atlanta, Georgia, was recently party to a remarkable experiment that quite literally left his colleagues struggling for words. Epstein asked fellow researcher James Lah to start counting out loud, while he held a small magnetic coil, roughly the size of a mobile phone, against Lah's forehead. "One, two, three," said Lah, quite happily. But when Epstein flicked on the power to the coil, Lah rapidly lost the power of speech. All that he could manage was "fo..., fo..., fo...". When Epstein cut the power again, Lah continued, "four, five, six," as if nothing had happened.
