The systemic organization of hemispherical asymmetry at the behavioral, neu
rophysiological, and biochemical levels was studied. An interconnection and
hierarchic coordination of the parameters of different levels were reveale
d, which are confirmed by multiple correlations between them. An interrelat
ion between the processes of peroxidation of brain membrane lipids, the lev
el of direct current potential, and the behavior of animals was shown. A si
gnificant difference in correlations between right-hander and left-hander a
nimals was found.
