DELETERIOUS EFFECTS ON HEALTHCARE AND PARTICULARLY DISRUPTION OF THE CHOLINERGIC SYSTEM HAVE BEEN REPORTED AFTER EXPOSURE TO RADIOFREQUENCY FIELD AT LOW POWER DENSITY.THIS WORK PRESENT A MULTIPARAMETRIC STUDY OF FREELY MOVING RAT WHERE NEUROPHYSIOLOGY WAS INVESTIGATED USING A NEUROCHEMICAL (BY MICRODIALYSIS TECHNIQUE), ELECTROPHYSIOLOGICAL, BEHAVIORAL (BY VIGILANCE STAGES QUANTIFICATION) AND THERMOPHYSIOLOGICAL APPROACHES.NO NEUROPHYSIOLOGICAL EFFECT HAVE BEEN NOTICED AFTER ELECTROMAGNETIC EXPOSURE AT 1,8 GHZ AND 2,45 GHZ FREQUENCIES AND FOR LOW POWER (NO THERMIC LEVEL) DENSITY. SIMILARLY COMPLEMENTARY STUDIES OF METABOLIC AND LIPIDIC COMPOSITION OF BRAIN TISSUE WAS PERFORMED USING NMR SPECTROMETRY AND FAILED STUDIES BY NMR AND FAILED TO SHOW ANY SIGNIFICANT EFFECT.
