The story is here: http://www.siliconvalley.com/latestheadlines/ci_6203742

excerpts:

new technology in Japan could let you control electronic devices without lifting a finger simply by reading brain activity. ... a reporter did simple calculations in her head, and the train sprang forward - apparently indicating activity in the brain's frontal cortex ... Activating that region of the brain ... is what makes the train run. ... When one stops the calculations, the train stops, too.
Wonder if that will eventually be able to be used to stop a train if the engineer falls asleep or is obviously inattentive to the subject at hand? interesting stuff.
