[65] irradiated Wistar rats with 10, 30 and 50mW/cm2 microwaves, and the results showed that in the cerebral cortex, only glycine (Gly) and asparagine (Asp) levels were increased. The direct cause of the observed neuronal damage may have been apoptosis induced by the microwave radiation, and an indirect cause may have been an increase in permeability of the blood-brain barrier (BBB), which would allow the traversal of toxic substances that could cause damage.
