The question of whether microwave irradiation in the absence of gross or focal heating has any effect on normal function of the blood‐brain barrier has not been clearly answered. Two reasons for this ambiguity relate to the unknown magnitudes of microwave‐induced effects and to the sensitivity and quantitative accuracy of measurement. Histological and physiological methods are compared. Seven different physiological methods that involve four different tracer‐input modalities, which are currently being used to study and quantify the blood‐brain‐barrier permeability, are discussed; their advantages and disadvan‐tages are presented and their applicability to the study of effects of microwaves on normal blood‐brain‐barrier function are compared.
