Bidirectional Effect of Repeated Exposure to Extremely Low-Frequency Electromagnetic Field (50 Hz) of 1 and 7 mT on Oxidative/Antioxidative Status in Rat’s Brain: The Prediction for the Vulnerability to Diseases

Figure 6

The basal (a) and open field-induced level of TAC (b) in the prefrontal cortex of the rat’s brain. Animals were exposed once to three times (-) to EMF of 1 or 7 mT or control conditions. Values are presented as . The lines show the direction of changes in the level of TAC in 1 mT (dotted line) and 7 mT (solid line) groups after each subsequent exposure. Statistically significant differences between animals from the same group are denoted ^#, ^##, and ^###, and these between experimental groups are denoted , , and .
