Fear is a vital defense mechanism to potential threats, which influenced by the cerebellum. While cerebellum’s role in acquiring fear responses well understood, limited knowledge exists about its involvement extinction. In this study, we investigated effects of cerebellar theta band transcranial alternating current stimulation (ctACS) administered during extinction training, based on previous evidence from animal studies suggesting oscillations associative memory formation. To end, thirty-seven healthy right-handed male participants were recruited for two-day differential renewal paradigm. On day 1, they underwent acquisition training context A followed B. 2, recall was tested contexts and One group received ctACS (6 Hz) training. The other sham ctACS. Although both groups demonstrated ability previously learned distinguish between low high threat stimuli, no significant differences observed groups, indicating that at frequency range did not impact acquired study. Nevertheless, using could still be useful future research, including brain imaging studies, better understand how cerebellum involved processes.
