Abstract
Introduction: Almost all of populations have involuntary irradiation from waves that emitted by base station antenna. This in vivo study was planned for evaluating the effects of 950 MHz waves of GSM mobile phone system on dentate gyrus long-term potentiation. Materials and Methods: 32 naive male Wistar rats (3 month old, 220 + 15 g) randomly divided in four groups: (LTP immediately after sham–exposed, LTP immediately after GSM exposed, LTP 3 hours after sham–exposed and LTP 3 hours after GSM). The exposure program was planned for 10 sessions at 3 days. Animals were exposed to electromagnetic field for 45-min in a circular plastic chamber (mean electric field = 60 V/m). After end exposure, anesthesia was induced for LTP induction. Field potentials were recorded and analyzed using the population spike amplitude, EPSP slope and spike delay time for 60-min. Results: There were no significant differences in population spike amplitude and spike delay time immediately after exposure. But these parameters, three hours after exposure were changed. Conclusion: This experiment provides that rat's long-term potentiation could be affected by the whole-body exposure to 950 MHz field of GSM mobile phone system
