I found the article pretty interesting to see where they were at with the research.
I couldn't, however, eliminate that funny thought in the back of the mind... If someone used these electrodes to control their locomotion, that would give a whole new meaning to "sleepwalking."

I don't mean to be insensitive... it was just one of those bizarre thoughts I couldn't let go.
