Abstract
Nine years (1977-1985) of experiments and theoretical modelling concerning the interactions between weak low-frequency electromagnetic (EM) fields and biosystems are summarized. The ill vitro reactivation of frog erythrocytes induced by EM signals is described. The influence of EM signals on the lectin-induced reactivation of human lymphocytes is discussed, and the main features of an interaction model based on the “microelectrophoretic effect” are sketched. Finally, some basic questions are raised, which are fundamental to the development of this area of research.
