Source passage
Source text · mention onlyOn the part of the principal, muscle-reading consists of an acute perception of the slight action of another's muscles. On the part of the subject, it involves a nervous impulse, accompanied by muscular action. The mind of the subject is in a state of tension or expectancy. A sudden release from this state excites, momentarily, an increased activity in the cells of the cerebral cortex. Since the ideational centres, as is usually held, correspond to the motor centres, the nervous action causes a motor impulse to be transmitted to the muscles. * * In making his way to the location of a hidden object, the subject usually does not lead the muscle-reader, but the muscle-reader leads the subject. That is to say, so long as the muscle-reader moves in the right direction, the subject gives no indication, but passively moves with him. The muscle-reader perceives nothing unusual. But, the subject's mind being intently fixed on a certain course, the instant that the muscle-reader deviates from that course there is a slight, involuntary tremor, or muscular thrill, on the part of the subject, due to the sudden interruption of his previous state of mental tension.
