Abstract
A simply constructed and arranged apparatus and technique are described for the measurement of the finger-withdrawal response which have certain advantages over those previously reported. A pointer attached to the finger interrupts a beam of light as it rises and falls without impeding the finger's movement. Pulses from photoelectric cells and the CS and UCS are simultaneously fed into the multi-channels of an electroencephalograph, producing a record of the amplitude of the response and the various time relations.
