Histochemical Study of Effects of Weak Electromagnetic Field on Structures of the Rat Midbrain. med./bio.

Published in: J Evol Biochem Physiol 2005; 41 (1): 119-125

Aim of study (acc. to author)

To study histochemically by the cytochrome oxidase activity-method of electromagnetic field effects on metabolic activity of the auditory (inferior colliculus) and non-auditory (superior colliculus) centers of the rat midbrain.
