[Biochemical asymmetry of the brain: myth or reality?].

Unilateral brain damage results in the appearance of oligopeptide factor of complete asymmetry (CAF) producing a lateralized effect on spinal centers during intracisternal administration. The action vector of CAF is determined by the side of brain damage. The right- and left-sided CAF differ in chemical structure. Their CAFs are species-unspecific. The findings suggest that there is a chemical labeling of the right and left brain in the mammals (including man). From this point of view, fundamental and medical aspects of biochemical brain asymmetry are analyzed.
