[Effects of hypogeomagnetic fields on the structural-functional activity of rat cerebral cortex]

Structural functional organization state of brain cortex has been determined by histological, hystochemical and morfometrical methods from 104 animals, which were exposed by long stay of hypogeomagnetic field. It is found the disturbance of brain cortex micro-circulation; the disturbance of the enzymes activity of oxidate-reductive types, analogous to hypoxic; monthly chronobiological cycle of neurons content of basic structural functional types replace by changes of this index. The authors suppose that as a result the desynchronization of brain cortex activity as functional system appear.
