ABSTRACT
Over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. This in vivo study was planned for evaluating the effects of whole-body exposure to 950 MHz field of GSM mobile phone system on rat dentate gyrus long-term potentiation. 24 naive male Wistar rats [3 month old, 225 +/- 25 g] were randomly divided in the three groups [sham-exposed, GSM and continuous field exposed]. The exposure program was planned for 10 sessions at 3 days. Animals were exposed to electromagnetic field for 45 minutes in a circular plastic chamber [mean power density=0.835 mW/cm[2]]. Immediately after end exposure, anesthesia was induced for long term potentiation [LTP] induction. Field potentials were recorded and analyzed using the population spike amplitude and EPSP slope for 60- min. There were no significant differences in population spike amplitude, EPSP slope and EPSP slope maintenance among the three groups. This study provides no evidence indicating that long-term potentiation can be affected by the whole-body exposure to low-power density of 950 MHz field of GSM mobile phone system
