Academician Petr Lazarev's scientific and organizational activities are briefly described. He has predicted, first, the law of interaction between various sets of receptors that occurs in solving problems by humans and, second, the existence of a special type of that interaction in which two or more receptor channels are either synchronized or combined into a single channel. The second option is referred to as synesthesia. Half a century later widespread interest to studies of this phenomenon is witnessed.
