In this study, we investigated possible biological effects on brain of rats exposed in vivo to electromagnetic (EM) fields -at frequencies of 900 and 1800 MHz-, generated in a GTEM chamber. The corresponding experimental system (ES) consisted of: a vector signal generator, a directional coupler, a spectrum analyzer, a power meter, and the GTEM chamber itself -where the animal was located with the help of an appropriate holder. The 1g averaged peak SAR and mean SAR values in the brain and whole-body of the rat were estimated from experimental power measurements, and with the aid of a FDTD software tool. The ES was also used to study the morphological effects on the brain in rats given subconvulsive doses of picrotoxin, showing that the signals produced acute influence on their neuronal activityspa© XXIII Simposium Nacional de la Unión Científica Internacional de Radio.
