[Trace elements in the neurophysiological mechanisms of the development of interhemispheric asymmetry]

The content of microelements in the cerebral cortex of rats featuring motor asymmetry was studied by the method of emission spectral analysis with inductively bound argon plasma. The content of microelements (Cd, Co, Cu, Fe, Mn, Mo, P, S, and Zn) differs reliably in the subdominant and dominant hemispheres. We propose that interhemispheric asymmetry of the content of microelements plays the key role in formation of the brain functional asymmetry.
