Non-Ionizing Electromagnetic Fields and Spatial Learning and Memory Functions

Exposure to nonionizing electromagnetic fields has been reported to affect the functions of the central nervous system. A consequence of functional disturbance in the nervous system is changes in behavior in the animal. Indeed, exposure to radio-frequency electromagnetic radiation (RFR) and extremely low frequency electromagnetic fields has been shown to affect behavioral functions. The following is a brief summary of experiments performed in our laboratory investigating the effects of electromagnetic field exposure on spatial learning and memory functions in the rat. These involve studies using the radial arm maze and the Morris water maze. Both mazes have been used extensively in the study of spatial memory and learning in rodents.
