The effect of some developmental abnormalities on the morphogenesis of human brain asymmetry during early embryonic stages was studied. Insignificant predominance of the left hemisphere (1-3%) was revealed in human embryos.
Histological and morphometrical analysis of the brain and peripheral analyzers revealed proliferative migration abnormalities of brain development and neuron differentiation in mammals during a space flight, which can limit space exploration.
