AB  - Freezing behavior is a fearful reaction to specific stimuli, most commonly observed by animals. One of the neurotransmission system most consistently linked with fear response is the GABAergic system, in which GABA through GABAA receptor can influence fear response. The aim of the present investigation was to examine the effect of IP injection of muscimol (GABAA agonist) and bicuculline (GABAA antagonist) with and without EMF exposure on the frequency of fear response. Fifty adult male rats weighing 180-200 g were used. Animals were divided in ten groups, of which five groups were exposed to ELF-EMF for 30 days at 8 h day-1 in a solenoid, creating an electromagnetic field of 500 µT by a 50Hz electrical current created. Animals were then treated with various doses of muscimol and bicuculline before being exposed to electrical shock. Each animal were received 100 electrical shocks every session. After shock induction, the fear response was determined by monitoring the reaction of shocked animals to a normal rat which was placed in the electroshock chamber. Data were analyzed by Mann-Whitney test and p
