To explore the effects of Electromagnetic pulse (EMP) exposure on the nervous system of rats. The Wistar rats were divided into four groups: three exposure groups and one normal control group. The measurement of ability of learning of rats was carried with Y-maze, followed by the detection of the content of neurotransmitters in different areas of cerebrum. Compared with control group, in the following three days of EMP exposure, the ability of learning of exposure groups decreased (P0.05). For one day group, in hippocampus, the content of 5-HT and DOPAC increased (P0.05), and in hypothalamus, the content of Dopamine increased (P0.05), whilethe content of Adr decrease ( P0.05). The content of Adr and 5-HT in hippocampus of the second day group reduced (P0.05). The content of Adr in hippocampus of the third day group was still lower than that of control group (P0.05). According to the results above, we can conclude that EMP exposure results in changes of the content of neurotransmitters in different cerebral areas of rats, lowering their ability of learning.
