A significant decrease in the enzyme level was revealed in the exposed animals in comparison to the sham-exposed animals (whole brain and hippocampus). The phenomen is non-thermal in nature. These findings indicate that this type of irradiation could affect membrane bound enzymes associated with cell signaling, proliferation and differentiation. This may also suggest an effect on the behavior of chronically exposed rats.
