Plasma DBH, platelet MAO and proteins of red blood cell membranes in individuals with variants of the normal EEG

Plasma DBH, platelet MAO and proteins of red blood cell membranes were examined in healthy male carriers of variants of the normal resting EEG. The variants included low-voltage EEG, badly synchronized alpha-EEG, diffuse beta-EEG and monotonous alpha-EEG. Mean DBH activity of the low-voltage EEG group was only half that of the monotonous alpha-EEG group. No difference between EEG types in platelet MAO activity and in polypeptide pattern of erythrocyte membranes after electrophoresis could be detected.
