Non-Conventional Communication

To try to overcome the problem of time delay in radio communication with deep space missions, a possible new type of direct communication between two persons has been investigated. The method consists in stimulating the first person by his performing mental arithmetic operations or remembering names. Coinciding responses from the second person have been measured with an electronic plethysmograph or finger volume change recorder. The response signals seem to be larger for stimulation than for control periods over distances of hundreds of miles. Thus a binary code communication device of large-small signals (like dots and dashes of the ternary Morse Code) is being attempted
