Russian researchers from Orenburg State University suggest an explanation for functional difference of visually symmetrical cerebral hemispheres.
      
      Researchers believe that concentration of microelements is one of key factors, defining different functions of the two cerebral hemispheres. Microelements are essential – they take part in vitamin and hormone synthesis, necessary for many enzymes, and play a significant role in metabolism and brain functioning.
      
      Rats with dominating right hemisphere had higher content of mercury and copper in cerebral cortex. Animals with mightier left cerebral hemisphere showed higher values for chrome, iron, vanadium, cadmium and lead. Scientists report even more differences.
      
      The phenomenon can be a consequence of difference functions of cerebral hemispheres.
