Transcranial Alternating Current Stimulation at Alpha Frequency Reduces Pain When the Intensity of Pain is Uncertain.

• Application of alpha tACS over somatosensory regions influences perceived pain• Alpha tACS compared to sham lowers both perceived pain intensity and unpleasantness• However, uncertainty about pain intensity moderates this effect• Perceived pain was lower during alpha tACS, only when pain intensity was uncertain• Alpha tACS has the potential to alleviate pain, particularly when pain is uncertain
