          Abstract

          Wistar rats were exposed to a 916 MHz, 10 W/m 2 mobile phone electromagnetic field for 6 hours a day, 5 days a week. Average completion times in an eight-arm radial maze were longer in the exposed rats than control rats after 4–5 weeks of exposure. Error rates in the exposed rats were greater than the control rats at 6 weeks. Hippocampal neurons from the exposed rats showed irregular firing patterns during the experiment, and they exhibited decreased spiking activity 6–9 weeks compared with that after 2–5 weeks of exposure. These results indicate that 916 MHz electromagnetic fields influence learning and memory in rats during exposure, but long-term effects are not obvious.

            The rodent hippocampus and spatial memory: from synapses to systems.

            Tara G. Martin, Steven E. Clark (2007)
            Although its operations are not limited to the spatial domain, there is a near consensus that the hippocampus plays a critical role in memory for place. This review aims to explore this role, with a particular emphasis on the functions performed by distinct hippocampal subregions. The use of innovative lesioning techniques, localized pharmacological treatments, and molecular genetic interventions is offering increasingly precise brain-regional specificity and temporal control. Together with the electrophysiological recording of neuronal activity, these techniques are beginning to shed light on the functioning of specific components of the hippocampal circuitry in the different phases of memory - encoding, storage, consolidation, and retrieval. In view of these developments, we examine the involvement of the hippocampus in the encoding versus retrieval of spatial memory, before turning to the issue of long-term information storage and the role of 'cellular' and 'systems' consolidation processes in the formation of lasting memories.

              Cognitive impairment in rats after long-term exposure to GSM-900 mobile phone radiation.

              Roger Tian, Gustav Grafström, Lars Malmgren … (2008)
              Considering the frequent use of mobile phones, we have directed attention to possible implications on cognitive functions. In this study we investigated in a rat model the long-term effects of protracted exposure to Global System for Mobile Communication-900 MHz (GSM-900) radiation. Out of a total of 56 rats, 32 were exposed for 2 h each week for 55 weeks to radio-frequency electromagnetic radiation at different SAR levels (0.6 and 60 mW/kg at the initiation of the experimental period) emitted by a (GSM-900) test phone. Sixteen animals were sham exposed and eight animals were cage controls, which never left the animal house. After this protracted exposure, GSM-900 exposed rats were compared to sham exposed controls. Effects on exploratory behaviour were evaluated in the open-field test, in which no difference was seen. Effects on cognitive functions were evaluated in the episodic-like memory test. In our study, GSM exposed rats had impaired memory for objects and their temporal order of presentation, compared to sham exposed controls (P = 0.02). Detecting the place in which an object was presented was not affected by GSM exposure. Our results suggest significantly reduced memory functions in rats after GSM microwave exposure (P = 0.02).
