The effects of EMP on behavior and neurotransmitters were reported by Wu et al [6]. Wistar rats were irradiated with EMP. The parameters of the pulse were: rising time 24ns, half duration 340ns, and electric field strength 40kV/m.

The rats were divided into four groups. Three exposure groups were examined on different days after exposure and one group was served as control. The measurement of learning ability of the rats was carried out with Y-maze, followed by the detection of the content of neurotransmitters in hippcampus and hypothalamus of their brains.

The training time was defined as the total training number that the rats could respond correctly in conditioned reflex for nine times in ten successive tests. The neurotransmitters including adrenaline (Adr), norepinephrine (NE), dopamine, DOPAC, 5-HT and 5-HIAA were detected with high effective liquid phase chromatography.

The results showed that in the three days following exposure, the training times of the exposed group increased significantly over that in the control group, indicating that the learning ability of the exposed group was decreased.
